Hangar Property & Hangarkeepers Legal Liability

Whether you own a private box hangar on an airport ground lease, share a corporate hangar with partners, or run an A&P/IA maintenance shop or FBO with customer aircraft inside your doors, standard commercial property insurance routinely excludes airport operations.

What Hangar & Hangarkeepers insurance actually covers

Because standard business insurers apply broad 'Airport/Aircraft Exclusions' the moment a loss happens inside the airport security fence, dedicated aviation property and premises policies are essential. Here are the six core building blocks.

1. Owned Hangar Building & Ground-Lease Structure Property

Most private and corporate hangars are privately owned buildings sitting on long-term municipal, county, or port airport ground leases (or residential airpark lots). We insure the hangar structure itself — including high-value bi-fold or hydraulic hangar doors, heating, and pilot lounges — at Replacement Cost against fire, wind, snow load, and aircraft/vehicle impact.

Real-world example: If a winter windstorm or heavy snow load damages your 60x60 box hangar roof or bends a $35,000 bi-fold hangar door, Hangar Property coverage pays for the repair.

2. Hangarkeepers Legal Liability (Non-Owned Aircraft in Your Care)

If a friend's, tenant's, or customer's airplane is parked inside your hangar or being moved by your tug, your standard liability policy excludes damage to property in your 'Care, Custody, or Control.' Hangarkeepers Legal Liability covers physical damage to non-owned aircraft while hangared, serviced, or taxied/towed on the ground.

Real-world example: If you lease a corner of your box hangar to a hangar-mate or perform an annual inspection in your shop and a falling light fixture or tug mishap dents their wing, Hangarkeepers pays for the repair.

3. Airport Premises Liability (Inside the Airport Fence)

Municipal and port airport ground leases require $1M to $5M in Aviation Premises Liability naming the Airport Sponsor/City/Port as Additional Insured. Unlike standard commercial GL (which often excludes airside accidents), Aviation Premises Liability is built specifically for hangars, ramps, and taxiways.

Real-world example: If a guest, vendor, or hangar tenant slips on an oil spot or icy apron outside your hangar door, Aviation Premises Liability defends you and the airport.

4. Tugs, Ground Support Equipment (GSE), Shop Tools & Avionics Benches

Covers your electric or gas aircraft tow tugs, GPUs (ground power units), hydraulic jacks, air compressors, A&P mechanic toolboxes, calibrated avionics test equipment, and spare aircraft parts stored inside your hangar.

Real-world example: If an electrical fire in the hangar shop destroys your aircraft tug, hydraulic jacks, and $40,000 in mechanic tools, GSE & Contents coverage replaces them.

5. Loss of Hangar Rental Income (For Hangar Landlords & Developers)

If you own a multi-unit T-hangar row or sublease space in a large corporate hangar to other aircraft owners, Loss of Hangar Rents reimburses your lost monthly tenant rent checks if a fire or windstorm renders the hangar unusable during reconstruction.

Real-world example: While a wind-damaged hangar row is being rebuilt over six months, Loss of Rental Income keeps your ground-lease payments and hangar loan covered.

6. Aviation Products & Completed Operations (For A&P / IA Shops & FBOs)

For commercial maintenance shops, avionics installers, and FBOs, Completed Operations covers claims alleging that faulty maintenance, inspection, or fueling caused an accident after the aircraft left your hangar.

Real-world example: If an aircraft suffers an in-flight engine issue weeks after an overhaul and the owner alleges improper torqueing by your maintenance shop, Aviation Products/Completed Operations defends your business.
How Aviation Underwriters Price Hangar Risks

What moves your premium

Aviation property and casualty underwriters look at four main factors when pricing a Hangar and Hangarkeepers policy.

1. Maximum Value of Any Single Non-Owned Aircraft & Total Hangar Aggregate

Hangarkeepers limits are set with two numbers: a Per-Aircraft limit (sized to the most expensive non-owned plane that ever sits in your hangar) and an Per-Occurrence limit (sized to the total combined value of all non-owned planes inside at once).

2. Private Storage Only vs. Subleased Space vs. Commercial Maintenance/Fueling

A private owner storing only their own airplane (with occasional visiting guest aircraft) rates much lower than a commercial A&P maintenance shop performing annuals, welding, or retail fueling.

3. Hangar Construction, Door Type, Heating & Fire Protection

All-steel clear-span hangars with updated electrical, UL-listed radiant heaters, and airport hydrant/foam access earn the best property rates.

4. Airport Authority Ground Lease Insurance Specifications

Every municipal, county, and state airport lease has specific Additional Insured, Waiver of Subrogation, and notice-of-cancellation clauses. We review your airport lease page by page so your COI is approved on the first pass.
