9.5 Aviation Hull Coverages & Aircraft Liability Coverages
Key Takeaways
- Aviation appears on the Series 17-70 as two separate 3% domains, hull and aircraft liability, and is licensed in New York as its own adjuster line under 11 NYCRR 26.3(c).
- The three hull bases are all risk ground and flight, all risk not in flight (covers taxiing), and all risk not in motion (covers the aircraft only while at rest).
- Hull is normally written on an agreed value basis, with separate in-motion, not-in-motion and ingestion deductibles and a disappearance provision for an aircraft unreported for a stated period.
- The five aircraft liability coverages are bodily injury excluding passengers, property damage, passenger bodily injury, medical payments, and admitted liability (voluntary settlement).
- The pilot warranty, the stated purpose of use and the territorial limits are the three coverage questions an aviation adjuster answers before touching damages.
Aviation Hull Coverages & Aircraft Liability Coverages
Exam Focus: Aviation appears on the Series 17-70 as two separate 3% domains — Aviation Hull (3%) and Aircraft Liability (3%) — so together they are worth as much as the Homeowners conditions or the whole Surety and Fidelity set. The New York general adjuster license does not include aviation (11 NYCRR 26.3(c) is a separate line), but the examination still tests it because 26.4(b) requires the exam to cover the principles and practices of the enumerated kinds of insurance. Learn the three hull coverage bases and the five liability coverages.
Why Aviation Is Written Separately
Every property and casualty form you have studied so far excludes aircraft. The Homeowners policy excludes aircraft liability; the CGL excludes bodily injury and property damage arising out of the ownership, maintenance, use or entrustment of any aircraft; the Business Auto form covers autos, not aircraft. Aviation is written by a small group of specialist markets and pools on manuscript forms, and it is licensed in New York as its own adjuster line — independent adjuster, aviation under 11 NYCRR 26.3(c).
Aviation Hull Coverages (3%)
Hull insurance is physical damage coverage on the aircraft itself — the airframe, engines, propellers, avionics and installed equipment. The whole of hull underwriting turns on when the aircraft is covered.
The Three Coverage Bases
| Basis | Covers physical damage | Premium |
|---|---|---|
| All Risk — Ground and Flight | While parked, taxiing, taking off, in flight and landing — the broadest form, and the one a lender will require | Highest |
| All Risk — Not in Flight | While on the ground, including taxiing, but not while in flight. A hangar fire is covered; an in-flight engine failure is not | Middle |
| All Risk — Not in Motion | Only while the aircraft is at rest — parked, moored or in a hangar. Any damage from the moment it begins to move is excluded | Lowest |
Definitional Trap. “In flight” generally begins when the aircraft moves forward in the take-off run and ends when it completes the landing roll; for rotorcraft it typically means whenever the rotors are turning. “In motion” means taxiing under its own power or moving from a prior application of that power. A question that puts an accident on the taxiway is asking you to separate “not in flight” (covered) from “not in motion” (not covered).
Named Perils
Smaller or older aircraft, and some ground-risk-only placements, are written on a named-peril basis: fire, lightning, explosion, windstorm, hail, theft, vandalism, riot, and collision with another object while not in motion. Anything not named — notably in-flight mishap — is outside the cover.
Deductibles
Aviation hull deductibles are keyed to the operating state:
- In-motion deductible — typically a percentage of the insured value, applied when the loss occurs while the aircraft is taxiing, taking off, in flight or landing.
- Not-in-motion deductible — frequently nil, because a parked aircraft presents a very different exposure.
- Ingestion deductible — a separate, often larger deductible for foreign object damage drawn into a turbine engine.
- Disappearance — most hull forms cover an aircraft that disappears and is unreported for a stated period (commonly 60 days) after the flight on which it was last reported.
Valuation
Hull is normally written on an agreed value (stated amount) basis. In a total loss the insurer pays the agreed value without depreciation argument, which is why the schedule must be reviewed at each renewal — and why partial losses are settled on a repair-cost basis with the agreed value as the ceiling.
Common Hull Exclusions
Wear, tear, deterioration, mechanical or electrical breakdown (unless resulting fire or other damage ensues); damage confined to a tire unless caused by fire, theft or vandalism; conversion or embezzlement by a person in possession under a lease or sale agreement; use for an unlawful purpose; operation outside the purpose of use stated in the declarations (pleasure and business, industrial aid, commercial, flight instruction, rental); and — critically — operation by a pilot who does not meet the pilot warranty in the declarations.
The Pilot Warranty is the aviation adjuster's first coverage question. The declarations name the approved pilots or state minimum qualifications — certificate level, total hours, hours in make and model, instrument rating, current medical and flight review. An otherwise covered loss with a non-approved pilot at the controls is a coverage denial, not a damage negotiation.
Aircraft Liability Coverages (3%)
Aviation liability is written as a set of separately scheduled coverages, and the tested skill is knowing which one responds and what its limit structure is.
1. Bodily Injury Liability — Excluding Passengers
Covers bodily injury to persons other than passengers — people on the ground, occupants of another aircraft, line personnel. It is written per person and per occurrence.
2. Property Damage Liability
Covers damage to property of others — the hangar struck on landing, the parked aircraft clipped while taxiing, the crops destroyed in a forced landing. It excludes property owned by, rented to or in the care, custody or control of the insured, which is why an FBO needs hangarkeepers liability for the customer aircraft in its hangar, exactly as a garage needs garagekeepers coverage (Section 8.4).
3. Passenger Bodily Injury Liability
Covers bodily injury to passengers. It is normally written with a per-passenger limit and a per-occurrence limit, and the per-occurrence limit is often expressed as the per-passenger limit multiplied by the number of seats.
4. Medical Payments
Pays reasonable medical expenses, regardless of fault, for injury sustained while in, entering or leaving the aircraft. It is usually split between passengers and crew, and crew medical payments are frequently excluded or separately sub-limited because the crew's injuries are expected to run through workers' compensation.
5. Admitted Liability (Voluntary Settlement)
A distinctly aviation coverage. Admitted liability offers a stated sum to an injured or deceased passenger or their representative in exchange for a full release, without proof of the operator's negligence. It is used to resolve passenger claims quickly and privately, most commonly on corporate flight departments where the passengers are employees or guests of the insured. Any admitted liability payment accepted is credited against the passenger bodily injury limit.
Limit Structures
| Structure | Meaning |
|---|---|
| Single limit | One limit for bodily injury (including passengers) and property damage per occurrence |
| Single limit with passenger sub-limit | A combined limit, but with a stated maximum payable per passenger — the most common structure in general aviation |
| Split limits | Separate per-person, per-occurrence and property damage limits |
Liability Exclusions
The insured's employees (workers' compensation territory); property in the insured's care, custody or control; contractual liability assumed beyond the policy's terms; use for an unlawful purpose or outside the stated purpose of use; operation outside the territorial limits; noise, pollution and electromagnetic interference on most forms; and war, hijacking and allied perils unless bought back by a war risk extension.
Adjuster Cue on Territory. Aviation policies state a geographic territory — commonly the United States, Canada, Mexico, the Bahamas and the Caribbean. A flight that ends in an accident outside the stated territory is a coverage problem before it is a damages problem, and the adjuster's first three questions on any aviation loss are always: Was the pilot approved? Was the purpose of use as declared? Was the flight within territory?
An aircraft insured on an “all risk — not in motion” hull basis is damaged when the pilot strikes a fuel truck while taxiing to the runway. Is the hull loss covered?
A corporate flight department wants to offer a stated sum to an injured passenger in exchange for a full release, without litigating negligence. Which aviation liability coverage provides this?
