FAA Grant Assurance 5: What It Means for Your Hangar Operations

Grant Assurance 5 has a dry name, Preserving Rights and Powers, and a straightforward core idea: keep enough control over your own airport to meet your other federal obligations, and do not sign that control away.

If your airport has ever accepted federal money through the Airport Improvement Program, you signed up for a set of obligations called grant assurances. There are 40 of them now, expanded from 39 under the 2024 FAA Reauthorization Act, and they bind you for years, sometimes decades, after the grant.

Most operators know they exist. Fewer could tell you what any specific one requires until the FAA comes asking.

Grant Assurance 5 is one worth understanding, because it sits underneath a lot of the day-to-day decisions you make about leases and land. This is what it means in practice, and what it asks you to actually do.

A quick caveat: this is a general explainer, not legal or regulatory advice. For how any assurance applies to your specific field, your airport attorney and your FAA Airports District Office are the authorities.

What Grant Assurance 5 Requires

The plain-English version of Grant Assurance 5 is this: you have to keep enough control over your own airport to be able to meet all your other federal obligations, and you cannot sign that control away.

When you accept AIP funding, you promise the FAA that the airport will be operated a certain way, kept available for aeronautical use, maintained, and run without unjust discrimination, among other things.

Grant Assurance 5 protects your ability to keep those promises. It says you will not sell, lease, encumber, or otherwise dispose of your rights and interests in the airport in a way that would leave you unable to carry out the assurances, without FAA approval. In effect, it stops you from writing an agreement today that makes it impossible to comply tomorrow.

That is the whole principle. Preserve the rights and powers you need to run a compliant airport. Do not give them away in a lease, an easement, or a side deal.

Why This Lands Squarely on Your Hangar Leases

Grant Assurance 5 can sound abstract until you realize that leases are exactly where rights and powers get given away, often without anyone intending to.

Every hangar lease, ground lease, and use agreement you sign transfers some bundle of rights to a tenant. Most of the time that is completely fine. The risk is in the terms that quietly go too far:

A lease that grants exclusive rights the FAA prohibits.
A term so long it ties the airport's hands for a generation.
A clause that limits your ability to reclaim or repurpose the land.
An arrangement that lets a parcel drift into a use the FAA never approved.

Any of those can put you crosswise with your assurances, and Grant Assurance 5 is the thread that ties the lease you signed to the federal obligation you may have just undermined.

This connects directly to the FAA's Hangar Use Policy, which holds that federally obligated hangars are meant for aeronautical purposes. Let a hangar slide into non-aeronautical use without the right approvals and documentation, and you have a compliance problem that traces back through your control of the property. The lease is where that story starts.

What "Sufficient Control" Looks Like in the File

The FAA does not just want you to have retained control in principle. When the question comes up, in a compliance review, an inspection, or a complaint investigation under FAA Order 5190.6B, you need to be able to show it. That comes down to documentation.

In practice, demonstrating that you have preserved your rights and powers means being able to produce, for any parcel or hangar, a clear record of who holds what rights, on what terms, for how long, and with what conditions on use and reversion.

That includes the current lease, its full term including options, any modifications, and evidence that the use matches what the property is obligated for. If a hangar's use changed, you want the approval trail that made it legitimate.

The airports that handle this well are the ones whose lease records are complete and current. The ones that struggle are the ones reconstructing terms from a filing cabinet and a long-tenured employee's memory, because the gaps in that reconstruction are exactly where a Grant Assurance 5 problem hides.

How Grant Assurance 5 Connects to the Others

Grant Assurance 5 rarely comes up alone, because preserving your rights and powers is what makes the other assurances possible. It sits alongside a cluster you will recognize:

Grant Assurance 19 requires you to operate and maintain the airport properly.
Grant Assurance 22 requires economic nondiscrimination, making the airport available on reasonable terms without unjust discrimination.
Grant Assurance 24 requires a fee and rental structure that keeps the airport as self-sustaining as possible.
Grant Assurance 38 addresses making land available for hangar construction under reasonable terms.

Every one of those depends on you having kept the control to actually deliver it, which is the job Grant Assurance 5 does. Give away the wrong right in a lease, and you can breach several assurances at once.

What to Actually Do About It

You do not need to become an FAA compliance lawyer to stay on the right side of Grant Assurance 5. You need three habits.

Review lease terms against your obligations before you sign. Watch for exclusive rights, excessive length, use restrictions, and reversion limits that could compromise your control. When in doubt, loop in your ADO or attorney.
Keep a complete, current inventory of every lease and agreement, with full terms and modifications, so you can demonstrate retained control on demand rather than reconstructing it under pressure.
Track hangar use against what each property is obligated for, so a drift into non-aeronautical use gets caught and documented rather than discovered during an audit.

All three come back to the same foundation: knowing exactly what you have leased, on what terms, and being able to show it.

That is why we built lease and compliance tracking into the Hangar Direct platform the way we did, with every lease, term, and change kept as a dated, exportable record, so that when the FAA asks what rights you have preserved, the answer is a report and not a scramble.

The tooling is secondary, though. The habit of keeping clear, current records of what you control is what actually keeps you compliant.
