What Airport Lease Audits Keep Finding

Audit after audit of airport lease operations finds the same handful of failures. That consistency is the useful part: predictable failures are preventable ones.

Read enough municipal and county audit reports on airport operations and something unsettling becomes clear: they keep finding the same things. Different states, different sized fields, different years, and yet the findings rhyme. Uncollected rent. Insurance that was required and never verified. Leases that expired years ago and were never renewed. No written policy for how leases get approved in the first place.

The consistency is the useful part. If auditors keep finding the same handful of failures, those failures are predictable, which means they are preventable. Here is what the audits actually say, why these problems keep happening, and how to make sure your field is not the next report.

The Findings Repeat, Field After Field

The specifics vary but the categories do not. A few real examples show the pattern.

In August 2025, an internal audit of Cobb County International Airport in Georgia (Report 2025-003) found that over a 21-month period the airport should have assessed and collected $81,148.66 in delinquency fees and collected none of it. The same report found the airport division had no written policy or guideline laying out how new leases get approved or renewed, and documented a payment that arrived 207 days late after being lost in the mail and not noticed for months, because nobody was monitoring whether it had come in.

A California county grand jury, reviewing El Dorado County's airports across 2025 and 2026, found tenants left on month-to-month tenancy for years, and revised lease templates that conflicted with the county's own written policy even after the board approved them in February 2026. A Texas city auditor reviewing San Antonio's aviation leases found that periodic lease monitoring was not consistently documented and that the department's contract administration plans did not accurately reflect the lease agreements actually in effect. Going back further, a Detroit auditor general review of Coleman A. Young International Airport found that 16 of 58 tenants had no lease at all, 7 percent had no rent amount listed, 14 percent were paying less than their agreement called for, and the airport could be losing $481,000 or more in potential revenue, partly because rates had not been updated since 2006. A Long Beach performance audit separately found that oversight of tenant insurance requirements was not applied consistently.

Line those up and four failure modes account for nearly all of it: money that should have been collected and was not, insurance that was required and never verified, leases that expired or never existed and were never fixed, and no written process governing any of it.

Why These Keep Happening

None of these findings come from bad people or lazy staff. They come from a structural problem: the records live in a form that cannot keep itself honest, maintained by people with more urgent things to do.

Uncollected rent and late payments slip because nobody is watching a live view of who owes what. A payment that goes missing is not noticed for months because nothing flags that it never arrived. Missing certificates of insurance accumulate because verifying and chasing them is manual, tedious work that loses every time it competes with an operational fire. Expired and month-to-month leases pile up because renewing a lease requires someone to notice it lapsed, and a filing cabinet does not send reminders. And the absence of a written approval policy is what happens when the process lives entirely in one experienced person's head and never gets written down before they move on.

In other words, these are not exotic failures. They are the natural end state of running a leasing operation on spreadsheets, paper files, and memory. The audit is just the moment the accumulated drift becomes visible.

Why It Is Worth Getting Ahead Of

An audit finding is not only embarrassing. It carries real consequences. Uncollected rent is money the airport was owed and did not get, which for a field bound by grant assurances to be self-sustaining is also a compliance issue, not just a budget one. Insurance that was never verified is the exposure that turns a hangar fire or a weather event into a liability the airport absorbs. And "no written leasing policy" is the kind of finding that follows an operation around, because it implies every individual lease decision was made without a standard, which is exactly the vulnerability a frustrated tenant or a plaintiff's attorney looks for.

The good news, again, is that because the findings are so predictable, the defense is too. You do not need to guess what an auditor will look for. The reports already told you.

How to Not Be the Next Finding

Work backward from the four recurring findings and the fixes are concrete.

For uncollected and late payments, keep a live view of who owes what and what has actually come in, so a missing payment surfaces in days, not after 21 months. For insurance, require certificates in every lease and verify them on a schedule, tracking coverage and expiration so gaps flag themselves instead of waiting to be discovered during a claim. For expired and holdover leases, maintain one complete inventory of every lease with its term and renewal date, and review what is expiring on a regular cadence so nobody sits on month-to-month for years by accident. And for process, write down how leases get approved, insurance gets verified, and rent gets collected, so the standard survives any one person leaving.

Underneath all four is the same requirement: one complete, current, auditable record of every lease, every payment, and every certificate, that does not depend on a single person to stay accurate. That is what auditors are really testing for, whether they say so or not.

The Quiet Version of an Audit-Ready Operation

An operation that would pass these audits does not feel like it is constantly preparing for one. It just runs on records that stay current on their own. Expirations flag themselves. Overdue payments are visible. Every lease is in one place with its terms and dates. The written policies exist because the system enforces them. When the auditor shows up, the answer to every question is a report you can run, not a weekend of reconstruction.

That is squarely what we built the Hangar Direct platform to do: keep leases, payments, and compliance records in one current, exportable place so audit prep stops being an event. But the principle holds regardless of what you run it on. The auditors have handed every airport in the country a free study guide. The failures are known. Fixing them ahead of time is a choice any operation can make before the report gets written, rather than after.
