Independent Internal Audit Program Glendale Airport Audit
Executive Summary
As part of our FY 2024 Audit Plan approved by the City Council, City of Glendale's
Independent Internal Audit Program (IIAP) conducted a performance audit of the City's
Municipal Airport (FAA code GEU). The audit aimed to evaluate compliance with
contract/lease terms between the airport and its customers, determine opportunities to
increase revenues, and address GEU’s operating deficit.
Audit Objectives:
The main objectives of this audit were to ensure the airport and its customers are
complying with lease and contractual obligations, and determining whether revenues are
accurately reported and recorded. Where possible, we also identified opportunities to
increase revenues. We did not specifically test for compliance with FAA regulations or
Arizona Department of Transportation (ADOT) rules/guidelines.
Audit Conclusions:
Overall, IIAP noted that revenues are not consistently collected or reported, compliance
with lease/contractual obligations is not consistently performed or enforced, and that
several opportunities for increased revenues exist, which will require significant funding,
strategic planning, and time to achieve.
Findings:
1. Information and payments received from many customers is random, at best.
Payments for commercial activity are rarely submitted timely, and there is little to
no documentation to substantiate the amounts provided.
Description:
IIAP judgmentally selected a sample of ten airport customers/business partners for
testing. The sample included the Fixed Base Operator (FBO), Glendale Aero Services,
and nine Specialized Aviation Service Operators (SASOs). Some items such as office
rental in the Terminal Building and land leases (for hangars and/or hangar associations)
are invoiced to customers through the City’s financial system. For other items such as
SASO commercial activity or gate cards, the airport is relying on its customers to self-
report and remit, or fees are collected upon transaction occurrence. Due to inconsistency
of billing and payment collection, along with batching daily receipts that may not identify
amounts per specific customer, there is no way to reconcile individual amounts to each
SASO/commercial business customer.
Severity: High
2. There are multiple instances where neither the customer nor the City are fulfilling
their contractual obligations. These could be related to untimely customer
payments and/or enforcement of late fees, providing insufficient support for
3
Independent Internal Audit Program Glendale Airport Audit
payment amounts, providing annual CPA-prepared financial statements, and/or
notifying customers of non-compliance. In addition, most leases contain terms that
are unfavorable for the City which remain in effect for decades in the future.
Description:
Overall, long-term contracts have been in place with the main airport business partners
for many years, with terms and rates that favor the customers compared to the City. Due
to the length of original contracts, improved terms and current market rates may not occur
for several decades with some existing customers. For example, the most significant
contract for the airport is with the FBO, and that carries an expiration date of 2041, with
two additional 10-year renewal options available – pushing existing terms to 2061. The
FBO contract (and some other SASO contracts) require the customer to provide annual
CPA-prepared financial statements to the City, but GEU management indicates no such
statements have ever been received. Without enforcing contractual obligations by both
parties, the City may have been receiving inadequate payments for years as mentioned
in finding # 1 and could continue to do so for many years in the future.
Severity: High
3. There are multiple opportunities to increase GEU revenues, most notably through
the development of airport property east of the runway. The City could also adjust
rates and fees to better align with similar airports in the area, offer new hangar
lease options, and/or provide its own fueling and other ancillary services.
Description:
Based upon discussions with GEU management and review of several Strategic Plans,
Business Plans, and rate/fee studies completed by various consultants, there are several
options for increasing airport revenues. The most significant opportunity is development
of the existing airport land east of the runway. That would allow for new office and/or
hangar leases at current market rates, with more favorable payment terms and contract
lengths to maximize City revenues. This development would be in several phases over
25 – 30 years and would require significant strategic planning and funding by the City.
There are some other options to increase revenues on the currently developed airport
property, such as constructing and operating its own fueling facilities and/or hangars on
the south end of the runway. These would also require some planning and funding, but
could be done in two or three years instead of 25 – 30.
Severity: Medium

Independent Internal Audit Program Glendale Airport Audit
A. Introduction
The City of Glendale's Independent Internal Audit Program (IIAP) conducted a
performance audit of the City's Municipal Airport (FAA code GEU). The audit was
performed to evaluate compliance with contract/lease terms between the airport and its
customers, determine opportunities to increase revenues, and address GEU’s operating
deficit.
B. Background
Glendale has owned and maintained an airport since 1971, and GEU has been at its
current location since 1987. There are approximately 500 acres of land, with a runway of
7,000+ feet and multiple hangars. GEU is a general aviation (GA) reliever airport for
Phoenix Sky Harbor, offering aircraft storage and maintenance with private operators
onsite providing flight instruction. There is no commercial airline traffic at GEU.
The City owns the fuel farm and leases it to Glendale Aero Services, the fixed base
operator (FBO). There are three 20K gallon above-ground fuel storage tanks. There is
approximately 660,000 sq ft of aircraft storage hangar space and 400 individual units;
20K sq ft of space is dedicated to various aircraft maintenance activities. There is a 22K
sq ft terminal building (two stories) with several businesses leasing office space; the
restaurant within the terminal is no longer in operation. Apart from the FBO providing
fueling services, major aircraft maintenance and other aircraft services, there are 20+
airport-related businesses on the property that provide flight training, storage services,
aircraft repair and maintenance, and various other services. There is no Active Rescue
and Fire Fighting (ARFF) station onsite; fire services are provided by the City from local
stations.
GEU is led by an Airport Administrator, who reports to the City’s Transportation Director.
There are seven additional airport FTE (and an intern), including airfield operations and
a Management Assistant, who is responsible for the business/financial operations of the
airport. Airport operations are funded from a mix of direct revenue, the City’s general
fund, and the GO Fund (transportation sales tax). Capital projects are funded by FAA
and/or ADOT grants, sometimes with required matching funds coming from the City. For
FY20-23, operational (non-capital) expenditures have exceeded operational revenues by
an average of $322K.
C. Objective
The main objectives of this audit were to ensure the airport and its customers are
complying with lease and contractual obligations, and determining whether revenues are
accurately reported and recorded. Where possible, we also identified opportunities to
increase revenues. We did not specifically test for compliance with FAA regulations or
Arizona Department of Transportation (ADOT) rules/guidelines.

D. Key Outcomes
The Glendale Airport has potential for growth and the chance to become self-sustaining
financially. However, it will require significant strategic planning, dedicated marketing and
development, substantial financial investment, and a great deal of patience. There are
some options available for shorter-term revenue gains – still requiring the attributes listed
above – but allowing for potential to reduce GEU’s operating deficit. Before any of these
capital investment decisions are made, however, the airport should address its existing
needs for ensuring accuracy of revenue collected, enforcing contracts and creating more
favorable terms, and ensuring both physical and human resources are optimized.
E. Audit Results and Recommendations
Finding 1:
Information and payments received from many customers is random, at best.
Payments for commercial activity are rarely submitted timely, and there is little to
no documentation to substantiate the amounts provided.
Condition
For fiscal years 2020 – 2023, operational (non-capital) airport expenditures exceeded
operational revenues by an average of $322K. In an attempt to verify reported revenues,
IIAP selected a judgmental sample of ten airport tenants/business partners including the
fixed base operator (FBO – Glendale Aero Services) and nine Specialized Aviation
Service Operators (SASOs) to test accuracy and timeliness of payments due.
The nine SASOs are:
1. Aerosim
2. Airwest Helicopters
3. Eagle Sport
4. Executive Aviation, LLC
5. Fox Aviation
6. Larry Afana
7. Reymundo Rodriguez
8. Skyquest Aviation
9. Glendale Hangars
IIAP requested the following for all ten customers:
• Copies of any contracts, agreements, leases, etc. currently in effect (could be for
building space, hangars, services, or other)
• History of payments received for FY 22 & FY23 (7/1/21 – 6/30/23)
• Any financial statements (annual from a CPA and/or monthly statements to support
the payment)
6
Independent Internal Audit Program Glendale Airport Audit
Based on the testing, the following observations were identified:
Information and payments received from many customers is random, at best. Payments
for commercial activity are rarely submitted timely, and there is little to no documentation
to substantiate the amounts provided. Airport staff frequently must disable/inactivate gate
access cards of customers just to get their attention and remind them of payments
due. The revenue recognition process is outlined below.
GEU management will invoice its customers (through MUNIS) for the following items:
1. Terminal lease office rental
2. Terminal office rental utilities
3. Land lease (such as hangar associations)
4. Regular tiedowns
5. Advertising in the terminal
The following items are not invoiced:
• Gate cards
• Commercial activity (SASO/aeronautical permit/business customer)
• Conference room rental
• Transient tiedowns
• Fuel flowage
For non-invoiced payments that are received at Cashiering, the general receipting
process is used and batched into a total for that day’s receipts. If Cashiering cannot
identify the customer (most non-invoiced customers do not have a unique record number
in MUNIS) and/or tie a payment to a specific invoice, they reach out to GEU’s
Management Assistant for help in determining to whom the payment belongs. If unable
to determine, the “vendor” field in MUNIS will show as blank, or “Airport”, or something
similarly generic. Depending on the cashier, they might enter the generic info into MUNIS
even if the customer’s name is on the check. Regardless, because each day’s receipts
are batched into one total, there is no way to reconcile individual amounts to each
SASO/commercial business customer.
In addition, some of these “unknown” payments get charged against the remitter’s
monthly water bill. This may create a credit balance in their Glendale water account and
cause the GEU Management Assistant to follow-up with the customer to find out why they
didn’t pay the airport. The vendor will say they already paid (some are set-up for autopay
through their bank). If applied to their water bill and then reversed upon researching the
transaction, Budget & Finance must now make correcting journal entries, and then the
customer’s water account may show additional monies due. Regardless, significant time
for research and correction can impact customer satisfaction and create incorrect
balances (albeit immaterial) within both the Water (enterprise) and general funds.
For all payments received at the airport, the Management Assistant creates a Treasurer’s
Receipt (TR), which is physically brought to Cashiering along with the credit card
7
Independent Internal Audit Program Glendale Airport Audit
receipts/checks by GEU staff. The time in transit and at Cashiering takes away from
employees performing their on-site duties at the airport. In addition, there is the risk of
having payments lost/stolen. Whether the payments arrive in person, via mail, or if they
were delivered by armored car, accounting is handled by Cashiering as detailed above.
There is hope that upon implementing the airport’s new Aerosimple software solution,
payment processing may operate more effectively. However, it is possible that the
Management Assistant will need to create an invoice after the fact for currently non-
invoiced items. Not only is this creating additional work, generally there is no supporting
documentation to validate the monies remitted (such as no report from the commercial
business customer’s financial system). As there is currently (or with Aerosimple in the
future) no way to validate the amount of business actually performed by the
SASO/business customer, we cannot know if Glendale is receiving our contractually
obligated percentage.
Criteria
Per contracted terms with the FBO and sampled SASOs, certain percentages of services
provided (fuel, repairs, etc.) to airport patrons should be remitted to the City. Generally,
payments are due to the GEU administrative offices by the 15th of the following month.
Depending on the contract, the customer should provide various levels of documentation
to support the amounts remitted each month.
Cause
Over the last several years, there has been turnover in airport administration which has
led to inconsistent revenue collection and lack of strategic focus. Prior management
didn’t aggressively pursue revenue growth or enforce timeliness of customer payments.
Additionally, there has not been an efficient system in place to process invoicing and
payments, causing a lot of manual work and follow-up. Underlying all of these factors
is the practice of customers operating within the “honor system” when it comes to
reporting revenues throughout the General Aviation (GA) industry.
Effect
The airport has been running at an operating deficit for many years, relying on annual
support from the City’s general fund. If allowed to continue unchanged, the operating
deficit will continue to grow as the costs to staff and maintain current GEU facilities will
only increase with inflation and further deferred maintenance.
Recommendation
Per discussion with GEU management, they have never received any CPA-prepared
annual financial statements from the FBO or any other customers. Per contracted terms,
the FBO and some other customers are required to submit their annual financials to the
8
Independent Internal Audit Program Glendale Airport Audit
City for review. Due to non-compliance with this requirement, along with the inability to
reconcile payments for any customer with commercial activity or other non-invoiced
payment obligations, IIAP recommends that the City exercises their contractual right to
request an outside CPA firm to conduct an additional audit of these parties. If the audit
(of up to/through the past six years) demonstrates underpayment to the City in excess of
two percent (2%) of amounts due, the customer is obligated to cover the costs of said
audit.
Note: The FY25 audit plan includes this CPA-performed review and the cost of said audit
will be paid by the IIAP. If the audit determines that the customers are obligated to pay
for those costs, IIAP will be reimbursed for the CPA fee and the airport will keep all
operational monies due to them from past periods that they are able to collect.
Management’s Response
Management concurs with the finding. We will implement and enforce an “audit” program
to collect any contractually required annual financial reports from customers. We will also
select customers to review three months’ worth of financial reports, expanding the review
to additional months if preliminary results warrant. If customers have no income to report,
they will still be required to submit a statement indicating “no income” for that period.
In addition, management will research the possibility of charging customers a yearly flat
user fee based on estimated annual revenue. We will also research options in the new
Aerosimple software to track pre-aggregated payments in MUNIS without adding to the
Management Assistant’s workload. Finally, we will coordinate with Budget & Finance to
ensure that payments sent directly to Cashiering are sent to the airport for processing
prior to posting.
The Airport Administrator and Management Assistant are responsible for implementing
this action plan. While some aspects can be implemented quickly (such as utilizing Vector
Systems for automatic billing of overnight parking and landing fees), other aspects will
take longer. Since the Aerosimple software implementation is already underway, we will
work with IT to optimize its pay portal. The proposed audit process will be developed by
June 30, 2025, following the outside CPA audit that IIAP noted above.
Finding 2:
There are multiple instances where neither the customer nor the City are fulfilling
their contractual obligations. These could be related to untimely customer
payments and/or enforcement of late fees, providing insufficient support for
payment amounts, providing annual CPA-prepared financial statements, and/or
notifying customers of non-compliance. In addition, most leases contain terms
that are unfavorable for the City which remain in effect for decades in the future.
9
Independent Internal Audit Program Glendale Airport Audit
Condition
IIAP attempted to determine the level of compliance with agreed upon terms between the
airport and its customer base, including consideration of terms’ intent and/or length in
effect. The same sample for the first objective was used for this objective. The names
of the customers and their corresponding contract information is listed below:
1. Aerosim - original contract 2017; most recent renewal 2023.
2. Airwest Helicopters - original contract 1976; present contract of 1997 most
recently amended 2009.
3. Eagle Sport - original contract 2017; original expiration date 2022, no record of
renewals found.
4. Executive Aviation, LLC - original contract 2018; original expiration date 2023, no
record of renewals found.
5. Fox Aviation - original contract for construction 2018; 20-year lease upon
Certificate of Occupancy with amendment in 2020, term expiring in 2040.
6. Larry Afana - original SASO contract executed in 2020 for five-year term.
7. Reymundo Rodriguez - original Aeronautical Business Permit 2023; most recent
renewal in 2024 through 12/31/2024.
8. Skyquest Aviation - six different suites in terminal originally contracted in 2017 for
one year with five successive one-year renewals available; in 2023, a new lease
was issued for one year with four successive one-year renewals available. There
is also a separate hangar lease from 2018 with an initial expiration in 2046.
9. Glendale Hangars - original contract 1986 for a 25-year term with two successive
10-year renewals; Valley Aviation Service is successor-in-interest 2005;
expiration is 2031.
Based on the testing, the following observations were identified:
For the most part, contracts have been in place for many years, historically with terms
which favor the customers compared to the City. For new contracts, language is
changed to make terms more favorable for the City and current market rates are utilized
with the ability to adjust rates at subsequent renewals. But due to the length of original
contracts, improved language and current market rates may not occur for decades to
come with existing customers. For two SASOs in the sample (Eagle Sport, Executive
Aviation, LLC), it is possible they are currently operating at GEU without a contract.
The most significant contract for the airport is with the FBO. The contract with Glendale
Aero Services was first executed in 1993 and amended several times in the 1990s and
2000s. The current version was made effective May 24, 2011, with a 30-year term. Upon
expiration in 2041, there are two 10-year renewal options available, pushing existing
terms to 2061. In addition to this contract, the FBO entered into a new land lease for
hangar construction in January of 2022, with a 20-year term upon Certificate of
Occupancy issuance. This is a primary example of the airport being handcuffed by its
existing contracts.
10
Independent Internal Audit Program Glendale Airport Audit
Criteria
The airport and its customers should be complying with their respective contract terms.
Generally, business contracts should benefit both parties and create a relationship of
cooperation and growth. Monetary terms associated with the contract should be flexible
and coincident with the marketplace over the life of the agreement. If necessary, length
of contracts and extensions should allow for regular adjustments to market.
Cause
For many years, the airport has provided its customers with very long leases/contracts
with terms that do not favor the City. Customers have come to expect automatic
renewals or extensions with the original terms intact, not accounting for changes based
on market rates or developments in the GA industry. The language in some of these
leases and contracts do not even provide for the City to determine whether hangars are
used for aviation purposes or contain any aircraft.
Effect
Due to lengthy and unfavorable contract terms with many customers, the airport is
potentially missing out on substantially higher revenues for years to come.
Recommendation
There are instances where neither the customer nor the City are fulfilling their contracted
obligations. These could be related to untimely customer payments, enforcement of late
fees, providing insufficient support for payment amounts, providing annual CPA-prepared
financial statements, and/or notifying customers of non-compliance. Specifically for the
FBO and at least one other customer (Airwest Helicopters (aka Hangars Unlimited)),
airport management indicates that no annual CPA-prepared financial statements have
ever been received as contractually obligated. As already indicated above in conjunction
with payment testing, IIAP recommends the City enforces the audit clause in each
contract and hires a qualified CPA firm to audit the customer’s financial records for the
number of years allowed per agreement.
Furthermore, IIAP recommends that no existing hangar leases are automatically
extended. Per the airport's lease agreements, at the end of each lease the hangar and
all improvements revert back to the City. The effect will begin with the first expiration in
2036 and continue generally through the next eight or so years thereafter. At each lease
expiration/revertment, the City has multiple options to choose from. The City could:
(1) Lease individual hangar units at the current market rate at time of revertment; or,
(2) Lease entire hangar structure (row) at the current market rate at time of revertment.
11
Independent Internal Audit Program Glendale Airport Audit
Either way, the City would need to determine if the airport would manage their own
structures or work with an outside party to manage them on its behalf. Preliminary
estimates using current market rates indicate that leasing out individual units requires
higher efforts and costs but provides the opportunity for much higher revenues. Whatever
decisions are made, they should be done in conjunction with the overall strategic and
marketing plans for development of the property on the east side of the runway, which
will be further discussed in the third audit objective.
Management’s Response
Management concurs with the finding. Airport management will continue to work with
City Procurement and the City Attorney’s Office (CAO) to review and update lease terms
to ensure they are fair to the City. As lease rates should always be based on fair market
value, airport management will determine the proper time for re-appraisal. Additionally,
lease templates will be updated to give airport staff explicit authority to enforce rules and
regulations, along with the right to inspect hangars (apart from Fire Department
inspections). The update will also address abandoning CPI adjustments for a flat growth
rate percentage (maybe three to five percent annually) to align with inflation. Finally,
management will create a standard operating procedure to collect late fees.
The Airport Administrator is responsible for plan execution. Some of these proposed
changes are already underway, as he reviews land lease language at each RFP to ensure
the City’s interests are protected, including required appraisals so that leases begin at fair
market value. For space (terminal) leases, management will develop an updated
ordinance to include provisions for fair market value as well. The updated ordinance and
template work with CAO will be presented to City Council by June 30, 2025.
Finding 3:
There are multiple opportunities to increase GEU revenues, most notably through
the development of airport property east of the runway. The City could also adjust
rates and fees to better align with similar airports in the area, offer new hangar
lease options, and/or provide its own fueling and other ancillary services.
Condition
IIAP attempted to identify opportunities for increased revenues at the airport, reducing its
reliance upon the City’s general fund to cover the operating deficit. Based upon
discussions with GEU management and the Strategic and Business Plans completed by
various consultants, there are multiple opportunities available to achieve this goal.
Consultants completed an Airport Strategic Plan (ASP) in 2021. Stakeholder interviews
for the ASP revealed that GEU has potential but needs prioritization and funding. The
airport is neither financially self-sustaining nor adequately marketed. Sentiment indicated
that development of its existing property east of the runway should target corporate
customers, which would help with financial support and allow for appropriate attention
12
Independent Internal Audit Program Glendale Airport Audit
paid to deferred maintenance. Stakeholders felt the airport had an overall positive
presence, although it was generally underutilized.
Consultants also completed an Airport Business Plan (ABP) in 2022. The intent of this
ABP was to identify potential new products/services to offer, develop some long-term
revenue sustainable practices, develop strategies to attract corporate and heavy aircraft
maintenance industries through a successful marketing plan, and develop a
comprehensive plan for the approximately 125-acre parcel on the east side of the runway.
Simultaneous with those objectives, GEU would need to address organizational structure
and staffing, develop infrastructure design standards, and complete much needed facility
aesthetic upgrades.
In conjunction with the ABP, consultants facilitated peer exchange sessions with three
Valley airports and initiated a Rates & Fees study with 10 peer airports. The airports
selected were similar in size and function, particularly with respect to General Aviation,
corporate aircraft, and related services. Airports were evaluated on number and types of
based aircraft, FBOs, SASOs, maintenance/repair/overhaul operations, leasable facilities
and land, and other aeronautical and general services. The biggest takeaways from the
study were making rates more consistent with peers, updating rates to market in older
contracts/leases as they are renewed or new agreements are made, and including CPI
adjustments and/or market valuations to keep rates in line with fluctuating costs. Since
GEU does not own any hangars directly and does not regulate the rates that private
owners charge, GEU is potentially missing out on higher revenues than their peers are
able to realize. However, the practice of leasing hangar space to others and having the
lessees "manage" the space and/or corresponding hangar association is the current
industry norm.
In February of 2024, the final coordination meeting for the GEU Eastside Development
Plan was held with various consultants and representatives from the City's Transportation
(including Airport), Economic Development, Fire, Development Services, Budget &
Finance, and IT departments, along with members of the City Attorney's and City
Manager's Offices. The outcome was a phased development plan that would span 25 -
30 years, requiring significant investment and a focused marketing strategy. It will require
a large effort to compete with other local municipal airports and become a self-sustaining,
regional airport. Rates for services will need to be more aligned with the market, contract
terms more favorable for the City, and GEU will need to "control" more aspects over its
revenue stream. Existing facilities require upgrades and will need to align with the spirit
and strategy around the new Eastside development.
If the initial focus of development is on rental revenues for office and/or hangar space, as
opposed to traditional SASO services, the potential for more consistent income exists,
especially when set at current market rates. If traditional SASO services from new
customers are sought, perhaps the airport could charge a larger fee up front for the permit
(covering one or two years in advance) and eliminate the need to collect monthly fees.
Regardless, once these new revenues have steadied, GEU can determine what other
13
Independent Internal Audit Program Glendale Airport Audit
airport-related opportunities (car rentals, immigration office, food service, unmanned flight
activity, etc.) to pursue depending upon the industry and market conditions at that time.
Per discussion with GEU management, there are some other potential revenue options
available now. The contract with the FBO does not grant them exclusive rights to
providing fuel. If the City chooses, they could construct fuel storage tanks to manage
themselves or pay another vendor to manage them on its behalf. The FBO currently
offers two types of fuel: 100LL and Jet A. The City could offer Octane 94 (or similar),
which is a popular alternative for smaller aircraft and not widely available in airports
around the state. This would likely attract a lot of traffic from aircraft at nearby airports to
refuel at GEU. The City could also offer 100LL and/or Jet A, undercutting the prices
charged by the FBO but still keeping a larger portion of sales than the nine cents per
gallon brought in by the FBO.
This option would require substantial capital outlay up front (but likely under $1 million)
and time to recoup its investment. Unfortunately, FAA/DOT grants generally cannot be
used for fuel facilities, so the City would need to explore funding options. If the City
decides to pursue their own fueling operation, it may also damage their relationship with
the FBO and possibly incur legal challenges.
Similar to the fueling option, the City could choose to build two rows of hangars on the
south end of the property that are currently and/or soon to be vacant. Per airport
management, approximately 20 hangars in each row could be built and managed in-
house or by paying another vendor to manage them on its behalf. The City would be able
to execute new contracts at market rates and with more favorable terms. Again, this
option would require an initial capital outlay and time to recoup its investment. But the
potential exists for higher earnings compared to current hangar revenues.
Criteria
The City should ensure that its assets and potential revenue sources are maximized to
benefit its citizens. Attracting new business partners to the City can generate tax and
operating revenues to fuel growth and better service delivery. Specifically for the airport,
new revenue streams could reduce reliance upon the general fund, allowing those monies
to be used for other City services.
Cause
The Glendale Airport has been underutilized for decades. There are many contributing
factors, including changes in leadership at multiple levels throughout the organization,
economic and budgetary conditions, and prioritization of initiatives. As with any large
investment for potential future growth, a thorough strategic plan and commitment to its
successful execution are required.
14
Independent Internal Audit Program Glendale Airport Audit
Effect
Without significant long-term investment and strategic planning, the airport will continue
to run at an operating deficit and draw down the City’s general fund.
Recommendation
To accomplish the goals outlined above, IIAP recommends that airport administration
completes several tasks:
(1) As current GEU Rules & Regulations/Standard Operating Procedures are outdated
and inconsistently enforced, update documents as appropriate and present them to City
Council for approval and subsequent distribution to all customers/stakeholders. As part
of these updates, GEU may wish to review its current fee schedule and institute new fees
for derelict aircraft and/or failure to register aircraft with the State of Arizona;
(2) Conduct an analysis of current staff to determine how their time is spent in a typical
week. IIAP is not implying that more staff are needed or that current staff are not doing
their jobs. Rather, IIAP suggests that a time analysis will help determine what percentage
of hours might be spent on routine or administrative tasks versus time that might be more
productive with respect to potentially optimizing revenue generation, facility upkeep,
safety/security, and customer service. This analysis may also identify opportunities for
automated solutions, cross-training, third-party operational agreements, etc.; and,
(3) Determine the feasibility of building its own fuel farm and/or two rows of hangars, along
with determining if said facilities should be run in-house or managed by an outside vendor.
This will require researching funding options and input from the City Attorney's Office.
Management’s Response
Management concurs with the finding. Airport management will heavily edit and/or create
new Airport Rules and Regulations, minimum operating standards, and standard
operating procedure manuals. All fees will be reviewed and updated annually. For the
second part of the recommendation, staff is already in the process of recording time spent
to complete assigned tasks, and management is building a spreadsheet to analyze how
many hours per position per year are required to safely and efficiently operate the airport
without cutting any corners. As to the last recommendation, management believes the
airport should operate a two-tank self-serve fuel station, with one tank containing 94
Octane unleaded gasoline and the other 100 Low Lead gasoline. Price point would be up
to two dollars over wholesale, which is a significant improvement over the 9 cents fuel
flowage fee at the FBO. The City would determine whether to build tanks ourselves (via
CIP process) or do an RFQ to have an outside contractor build the tanks and keep a
percentage of our fuel sales. As part of a future Master Plan developed by the Airport
Administrator and the Transportation department, the City will also address potential
15
Independent Internal Audit Program Glendale Airport Audit
buildout of new hangars on existing developed land, in addition to the proposed east side
property development.
The Airport Administrator, along with Operations and Security staff, are responsible for
the first part of plan execution, which will require public input/review and City Council
consideration (including updated rates/fees). Anticipated completion is December 31,
2025. All staff are participating in the second part, with expected completion by November
30, 2024. The Airport Administrator and Transportation leadership are responsible for
developing the Airport Master Plan – which will be funded with grants provided by the
FAA and ADOT – and could begin in FY26.
F. Process Improvement Opportunities
With implementation of the new Aerosimple software, GEU can streamline invoicing and
receipting for customer payments. Airport administration should continue to work closely
with IT and Budget & Finance (and perhaps Organizational Performance) to improve the
process and more accurately post revenue into MUNIS.
G. Audit Scope and Methodology
IIAP conducted a limited scope performance audit of the Glendale Airport, concentrating
on lease/contract compliance, revenue recognition, and potential opportunities for
reducing the operating deficit. We did not specifically test for compliance with FAA
regulations or Arizona Department of Transportation (ADOT) rules/guidelines. We
believe that the evidence obtained provides a reasonable basis for our findings and
conclusions based on the audit objectives.
IIAP determined internal controls over the following areas were relevant to our objectives:
• Timeliness, consistency, and accuracy of invoices/payments for GEU’s customer
base;
• Compliance with various contract/lease terms for the customers sampled.
To accomplish our objective, IIAP performed the following activities:
• Interviewed members of the GEU administrative team and staff, as well as relevant
staff in IT and Budget & Finance;
• Obtained and reviewed the agreements currently in place with a judgmentally
selected sample of ten GEU customers; and,
• Obtained and reviewed multiple consultants’ reports and recommendations, along
with attributes of similar airports of the surrounding geographic area.

H. Data Reliability
The primary data utilized for the work performed in this audit was obtained directly from
the Tyler MUNIS Simplicity System, the City’s financial system of record, to analyze
payments and operational deficits. MUNIS data reliability is reviewed annually during the
audit of the City’s financial reports and the Annual Comprehensive Financial Report
(ACFR) performed by the City’s external auditor. IIAP also analyzed the current contracts
and leases in place for the sampled customers.

Definitions of Audit Findings Rankings
We assigned the risk rankings based on our professional judgment. A qualitative
assessment of high, medium or low helps to prioritize implementation of corrective action
as shown in the table below.
High
Critical control weaknesses that expose the City to a high degree of
combined risks. Recommendations from high-risk findings should be
implemented immediately (preferably within 3 months), to address areas
with most significant impact or highest likelihood of loss, misappropriation
or damage related to the City assets.
Medium
Represents less than critical weaknesses that expose the City to a moderate
degree of combined risks. Recommendations arising from medium-risk
findings should be implemented in a timely manner (preferably within 6
months), to address these risks and strengthen or enhance efficiency in
internal controls on areas with moderate impact and likelihood of exposure.
Low
Represents a low level of risk or control weaknesses and the exposure is
not likely to expose the City and its assets to significant losses. However,
they should be addressed in order to improve efficiency and effectiveness
of operations. Recommendations arising from low-risk findings should be
implemented within 12 months.
