How to Track Hangar Tenant Insurance Compliance

Tenant coverage almost never lapses because it was expensive. It lapses because nobody was tracking the paperwork.

Here is a number worth sitting with before we get into process. A full year of $1 million liability coverage on a Cessna 172 costs somewhere between $200 and $550, depending on the policy. That is less than a decent headset.

So when a tenant's coverage lapses, it almost never lapses because the coverage was expensive. It lapses because nobody was tracking the paperwork.

That distinction matters, because it means the problem you are actually trying to solve is not a cost problem. It is a detection problem. And detection problems have solutions.

If you manage hangar tenants at an airport or an FBO, tracking insurance compliance is one of those tasks that feels small until the day it isn't. This is how to do it properly, whether you are doing it by hand or looking for a way to stop.

Why a Missing Certificate Is a Real Financial Exposure

When a tornado tore through John C. Tune Airport in Nashville in 2020, it destroyed 92 aircraft. The airport authority's insurer paid out $5.5 million in property damage and $700,000 in business interruption. The authority estimated rebuilding would cost more than $15 million, and the fight to close that gap ran past $10 million.

Part of the reason: a lot of aircraft owners assumed the FBO's insurance would cover them. It did not. Hangarkeeper's liability coverage generally protects against FBO negligence, not acts of God. Owners without their own hull coverage were simply out of luck, and the airport was left holding exposure it thought had been transferred to tenants years earlier.

That is the shape of the risk. It is not that any single tenant is a huge liability on a normal Tuesday. It is that the day something goes wrong, a fire, a storm, a lightning strike, the only thing standing between you and a claim is whether the documentation was current.

And nationally, that documentation is in worse shape than most operators assume. The GAO found that 10 to 20 percent of general aviation aircraft carry no liability insurance at all, and 39 of 50 states do not require any. In commercial real estate, where compliance is arguably taken more seriously, certificate compliance rates across many property portfolios still sit below 50 percent.

You are managing a slice of that same problem. The good news is you can manage it well.

What You Actually Need to Verify for Every Tenant

Tracking compliance is not just confirming a certificate exists. A certificate that exists but names the wrong party or expired last month is worse than useless, because it gives you false confidence.

Here is what a complete check covers for each tenant:

The certificate of insurance is current. Real expiration date, not a renewal the tenant promised to send. Roughly a quarter of all COIs expire in January, which creates a predictable pileup that manual systems tend to miss.
Your airport is named as additional insured. This is the single most commonly botched item on a certificate. Industry data on contractor submissions puts additional-insured errors at the top of the rejection list. Without that language, your indemnification and additional-insured protection may not actually hold when you need it.
The coverage types and limits meet your lease requirements. For most operations that means general or premises liability at $1 million or more per occurrence, hangarkeeper's liability where you store or handle tenant aircraft, and hull coverage on the aircraft itself. Write the minimums into your lease so there is something concrete to check against.
The aircraft on the policy matches the aircraft in the hangar. Tail numbers change. Aircraft get sold. A policy covering an airplane the tenant no longer owns is a gap hiding in plain sight.
The lease language does not quietly void the coverage. AOPA has warned for years that the hold-harmless clauses now standard in most hangar leases can void a tenant's aircraft policy entirely if the tenant signed without underwriter approval. Many aircraft policies exclude liability assumed under private contract. A tenant can be fully insured on paper and completely uncovered at claim time. Worth flagging to tenants directly.

Get those five things right for every tenant and you have covered the vast majority of your real exposure.

How to Track It by Hand, Step by Step

If you are doing this manually, and most operations still are, here is the workflow that actually holds up.

Build one master list. Every tenant, every hangar, every required document, in a single place. Not a spreadsheet on one person's laptop and a folder in someone else's email. One list.
Log every expiration date. Insurance, airworthiness, lease term. This is the spine of the whole system. If you only track one thing, track dates.
Set reminders ahead of each date. Thirty to sixty days out gives a tenant time to renew and gives you time to chase if they don't. A reminder that fires the day coverage expires is not a reminder. It is a postmortem.
Chase the renewals. This is the part nobody enjoys and everybody underestimates. Operators report spending 8 to 15 hours a week on this, which works out to more than 500 hours a year, or something close to $27,000 to $36,000 in labor at a normal hourly rate.
Verify each new certificate before you file it. Do not just confirm a document arrived. Confirm it names you as additional insured, meets your limits, and covers the right aircraft. A large share of first-time certificate submissions get rejected for exactly these reasons.
Keep the audit trail. Save every version, every reminder you sent, every confirmation. When the FAA, an insurer, or your board asks, you want to produce it in minutes, not spend a weekend reconstructing it from memory.

None of this is complicated. It is just relentless, and it never stops.

Where the Manual System Quietly Breaks

The manual method works right up until it doesn't, and it usually breaks in ways you don't see coming.

It breaks at staff turnover. When compliance lives in one person's spreadsheet and email folder, their institutional knowledge walks out the door the day they leave.

It breaks in January. A quarter of your certificates expire at once and the reminders don't scale.

It breaks on verification. Catching a missing additional-insured line on the fortieth certificate of the month is exactly the kind of thing a tired human misses.

It breaks on visibility. A spreadsheet can tell you what you typed into it, but it cannot tell you, at a glance, on a Thursday morning before a board meeting, who is actually compliant right now.

The result is predictable. Manual tracking tends to land operators at 60 to 70 percent compliance. That remaining 30-plus percent is not a rounding error. It is the exact population that turns into a liability the day the weather turns.

Automating the Whole Thing

This is the part where tracking insurance compliance stops being a job someone does and starts being something the system does on its own.

The core idea is simple. Instead of you collecting documents, tenants upload their own through a self-service portal. When a certificate comes in, OCR reads it and pulls out the policy number, coverage dates, limits, and insured aircraft automatically, so there is no manual data entry and no transcription error.

Everything lands on a dashboard that color-codes each tenant by status, so expired and expiring items are obvious in about thirty seconds rather than after an afternoon of cross-referencing. The platform contacts tenants before their coverage lapses, without you lifting a finger. And when the audit comes, you export a clean report formatted for FAA Grant Assurance compliance or a board meeting.

Operators who make this switch generally move from that 60-to-70 percent range to above 90 percent within the first couple of months. That is not because their tenants suddenly became more responsible. It is because the tracking stopped depending on a person remembering to do it.

The Math Underneath

The math is the same math we started with. A tenant's coverage costs a few hundred dollars a year. The loss it protects against can run into the millions. The entire gap between those two numbers is bridged by one thing: whether somebody, or something, kept the paperwork current.

You can keep doing that by hand. Plenty of good operators do. But if you would rather your team spend those 500 hours running your operation instead of chasing certificates, that is exactly what we built the compliance module for.
