Centennial Airport's Eighty-Two Percent Rent Hike and What the FAA's Response Tells Every GA Pilot About Hangar Rights

T-hangar tenants at Centennial Airport in Colorado received an 82% rent increase in a single billing cycle. When pilots filed a formal complaint with the FAA, the agency declined to reconsider its earlier decision - one that had not sided with the tenants. The outcome is a clear-eyed lesson in how much leverage a GA pilot actually has when an airport authority raises rates.

What Happened at Centennial Airport

Centennial Airport (KAPA), located south of Denver in Arapahoe County, consistently ranks among the busiest general aviation airports in the country. T-hangars there are working infrastructure - individual, single-aircraft storage units that protect planes from hail, ice, and weather exposure. For many pilots, a T-hangar is the difference between flying regularly and leaving an aircraft tied down on the ramp.

When the airport authority raised T-hangar rents by 82%, tenants pushed back at the local level first. When that produced no results, some filed a formal complaint with the FAA. The agency’s response was to stand by its prior ruling and decline further action.

How the FAA Complaint Process Actually Works

Airports that receive federal funding through the Airport Improvement Program (AIP) accept binding obligations called grant assurances in exchange for that money. Grant Assurance 22 specifically requires airports to make facilities available on reasonable terms and to avoid unjust economic discrimination against users.

When pilots believe an airport is violating those assurances, the formal mechanism is a Part 16 complaint - named after Title 14 of the Code of Federal Regulations, Part 16. It is the FAA’s Airport Compliance Program dispute resolution process. The process is slow and documentation-heavy, but it exists precisely for situations like this.

The pilots at Centennial used it correctly. The FAA’s answer was still no.

Why the FAA Didn’t Intervene - And What That Actually Means

The FAA’s decision does not mean the increase was fair or beneficial to GA. It means the agency determined the airport had legal authority to set those rates, and that the increase did not cross the specific threshold that triggers federal enforcement.

The grant assurance language around “reasonable rates” gives airports significant legal latitude. Courts and the FAA have historically allowed airports to set rates based on cost recovery, market conditions, and capital needs. If an airport can justify an increase through operational costs or comparable market data, the FAA’s practice has been to defer to airport management.

The Part 16 process is not a rent control mechanism. It addresses discrimination - an airport charging one category of user more than another for identical facilities, or arbitrary treatment with no policy basis. An across-the-board increase, even a steep one, is far harder to challenge under that framework than selective or preferential pricing.

Why Hangar Costs Are Rising Everywhere

Centennial is not an isolated case. Hangar costs have been climbing at airports across the country for several years, driven by compounding pressures.

Construction costs for new hangars have risen sharply - labor and materials make building a new T-hangar today significantly more expensive than a decade ago. Many airports operate on thin margins and are expected to be financially self-sustaining, which forces them to recalculate what existing infrastructure actually costs to maintain, insure, and eventually replace.

Demand is also outpacing supply. Growth in the experimental and light sport segments has added pilots looking for hangar space at facilities where inventory has not meaningfully expanded. Centennial sits in one of the most expensive real estate markets in the country, and airport authorities factor land value into how they price the space above it.

None of that makes an 82% single-cycle increase easy to absorb. For pilots on a realistic GA budget, a doubling of the monthly hangar bill can make continued aircraft ownership financially unworkable.

What Pilots Can Actually Do

Read your current lease today. Understand how much notice the airport is required to give before raising rates, whether there is a cap on annual increases, and whether a defined review period exists. Older leases at GA airports sometimes carry tenant protections that newer standard agreements have stripped out.

If rates are being applied differently to different categories of users at a federally funded airport, document it. Keep records of what comparable tenants pay and retain all communications with airport management. That documentation is the foundation of any future Part 16 complaint - and even an unsuccessful complaint creates a public record that signals to airport management that tenants are engaged.

When shopping for a home base where cost stability matters, ask airports directly about their rate-setting history over the past decade. Airports that publish a formal rate schedule and are transparent about their process tend to be more accountable to it. At privately owned airports that do not receive federal funding, grant assurances do not apply at all - the owner sets rates freely, and a pilot’s primary recourse is the lease terms or relocating the aircraft.

Resources for Affected Pilots

The Aircraft Owners and Pilots Association (AOPA) has been tracking hangar availability and cost as a priority issue and has published guidance on tenant rights and the Part 16 process. Their advocacy staff is a useful first contact before initiating a formal complaint.

The Experimental Aircraft Association (EAA) has focused on the supply side - specifically how airport land-lease arrangements and municipal approval processes slow new hangar construction. Their position is that the hangar shortage is partly a regulatory bottleneck, not just a market problem, and that streamlining the path to building new capacity would reduce price pressure over time.

Those are medium- and long-term solutions. In the near term, the Centennial outcome is a practical correction to a common assumption: that there is a meaningful federal backstop protecting individual pilots from steep airport rate increases. The FAA operates within a specific legal framework that gives it defined authority and defined limits - and those limits fall short of what many pilots believe they cover.

Key Takeaways

• Centennial Airport (KAPA) raised T-hangar rents by 82% in a single billing cycle; the FAA declined to intervene after a formal Part 16 complaint.
• Grant Assurance 22 requires airports to offer facilities on “reasonable terms,” but the FAA gives airport authorities wide latitude on rate-setting as long as increases are applied uniformly and can be justified by costs or market conditions.
• The Part 16 complaint process addresses discrimination and arbitrary exclusion - not affordability. Across-the-board increases are difficult to challenge under this framework.
• Hangar cost increases are a national trend driven by higher construction costs, flat inventory growth, and rising land values.
• Pilots should read their current lease, document any unequal rate treatment, and consult AOPA or EAA before filing a formal complaint.
