📋 '''Hangarkeepers liability''' is a specialized form of [[Definition:Liability insurance | liability insurance]] that protects operators of aircraft storage, maintenance, and service facilities against claims for damage to aircraft in their care, custody, or control. In [[Definition:Aviation insurance | aviation insurance]], this coverage fills a specific gap: a standard [[Definition:Commercial general liability (CGL) | general liability]] policy typically excludes damage to property held by the insured, which means that a fixed-base operator (FBO), maintenance repair and overhaul (MRO) provider, or hangar operator would be uninsured for damage to a customer's aircraft absent a dedicated hangarkeepers policy. The coverage responds when the facility operator is legally liable for loss or damage — whether caused by fire, windstorm, employee negligence, equipment malfunction, or other insured perils — to aircraft entrusted to them.

⚙️ A hangarkeepers liability policy is structured around the [[Definition:Bailment | bailee]] relationship: the facility operator takes temporary possession of the aircraft owner's property and assumes a duty of care. Coverage is usually written on either a "legal liability" basis, where the insurer pays only if the operator is found legally responsible for the damage, or on a broader "direct damage" basis, which covers physical loss or damage to aircraft in the operator's care regardless of fault — functioning more like a [[Definition:Property insurance | property]] policy for the benefit of the aircraft owner. Policy limits are typically set per aircraft and in the aggregate, and the [[Definition:Underwriter | underwriter]] evaluates factors such as the number and value of aircraft typically housed, the quality of the facility and fire suppression systems, the operator's maintenance procedures, and the geographic location's exposure to weather events. [[Definition:Deductible | Deductibles]] and [[Definition:Exclusion | exclusions]] vary; common exclusions include wear and tear, pre-existing damage, and loss arising from the operator's use of the aircraft in flight.

🔧 For anyone operating in the aviation ground services ecosystem — from small regional FBOs to large MRO complexes — hangarkeepers liability is not optional but a commercial necessity. Aircraft owners and [[Definition:Aircraft lessor | lessors]] routinely require proof of adequate hangarkeepers coverage before entrusting high-value assets to a third-party facility, and lease agreements or service contracts often specify minimum limits. A single incident — a hangar fire destroying multiple aircraft, for example — can produce claims running into tens of millions of dollars, making the coverage essential for the operator's financial survival. [[Definition:Insurance broker | Brokers]] specializing in aviation placements coordinate hangarkeepers liability alongside the facility's general liability, [[Definition:Products liability insurance | products liability]], and [[Definition:Workers' compensation insurance | workers' compensation]] programs to build a comprehensive risk transfer package.
