Aviation hull insurance is the first-party cover indemnifying the aircraft owner or operator against physical loss of or damage to the aircraft, including the airframe, engines, avionics and fixed equipment, normally on an agreed-value all-risks basis with separate war and allied perils cover.
Category: Aviation insurance Also known as: aircraft hull insurance, hull all risks aviation First codified: Lloyd’s market wordings from 1911; LSW 555 series of hull wordings Related legislation: Civil Aviation Act 1982 [1]; Air Navigation Order 2016 [2]; EU Regulation 785/2004 (retained law) [3]
Aviation hull insurance covers physical loss of or damage to the aircraft itself, including the airframe, fitted engines, avionics, instruments, communications and navigation equipment, and other property attached to or forming part of the aircraft. The cover is normally written on an ‘agreed value’ basis: the policy schedules a specific value for the aircraft that the insurer agrees to pay in the event of a total loss, removing the need for protracted post-loss valuation disputes characteristic of marine and other property classes [4][5].
The standard wording for commercial airline business is the LSW 555 family of hull all-risks wordings, supplemented by the LSW 555B wording for separately rated war and allied perils. The wordings are maintained by the Aviation and Aerospace Standing Committee of the Lloyd’s Market Association and are subject to extensive market-specific endorsements. General aviation business uses the AVN 38B and related wordings, with simpler structures and more standardised exclusions [4][5].
Cover responds to physical damage from any cause not specifically excluded, on the ‘all risks’ principle. The principal exclusions are war and allied perils (transferred to a separately rated war risk cover), wear and tear, deliberate damage, nuclear risks, and specifically excluded events (such as confiscation by the state of registry). The cover may apply only when the aircraft is in flight (in-flight cover), only when on the ground (ground cover), or at all times — the choice depending on operator preference and pricing [4][5].
Aviation hull insurance falls within the general law of insurance contracts in the UK, with the Insurance Act 2015 governing the duty of fair presentation and the law of warranties for commercial contracts. The Marine Insurance Act 1906 does not directly apply to aviation insurance but has informed the development of aviation wordings through historical Lloyd’s market practice [1][6].
EU Regulation 785/2004 on insurance requirements for air carriers and aircraft operators (as retained in UK law after Brexit) sets minimum insurance requirements for passenger, baggage, cargo and third-party liability but does not directly mandate hull insurance for operators (although hull cover is invariably required by financiers and lessors). The Air Navigation Order 2016 requires certain operators (including holders of UK Air Operator Certificates) to maintain insurance to specified limits, with detailed CAA guidance on acceptable arrangements [2][3].
Where an aircraft is financed or leased, the financier or lessor will normally require contractual cover specifications including hull and liability limits, named loss payees, breach-of-warranty cover, war and allied perils cover and a ‘Lessor Hull and Liability’ endorsement (typically AVN 67B or AVN 99 or successor wording) that protects the lessor’s separate interest in the aircraft even if the operator’s cover is invalidated by some act or omission of the operator [4][5].
The hull all-risks programme for a commercial airline is normally a single policy covering all aircraft in the fleet, with a schedule of agreed values and specified deductibles per aircraft. Deductibles range from US$100,000 for short-haul jets and turboprops to US$1m or more for widebody aircraft, reflecting both the relative frequency of minor damage on busy short-haul operations and the cost of repair on larger aircraft. The deductible structure can be supplemented by deductible buy-down covers for individual operators that prefer to retain less risk [4][5].
Underwriters assess the risk based on fleet composition (type, age, configuration), route structure (geography, frequency of high-risk airports), claims experience, safety record, maintenance arrangements (in-house or third-party MRO), pilot training and crew rostering practices, and safety management system maturity. Premium is typically expressed as a base rate plus per-flying-hour or per-departure rates, with adjustments at year-end based on actual exposures [4][5].
Hull war and allied perils cover is written separately, typically through a panel of specialist war risk syndicates at Lloyd’s and in continental Europe. The LSW 555B wording covers war, hijacking, sabotage, riots, civil commotion and other ‘AVN 48B’ perils excluded from the basic hull policy. Following the 2022 Russian lessor losses arising from the Ukraine invasion and the Russian government’s subsequent restrictions on returning Western-leased aircraft, war risk wordings have been materially restricted and rates have risen sharply [4].
Airline hull all risks: the standard product for commercial airlines on LSW 555 family wordings.
General aviation hull: simpler wordings (AVN 38B and equivalents) for privately operated aircraft.
Helicopter hull: distinct wordings reflecting the higher claims frequency and specialist missions of rotorcraft.
Lessor hull and liability: insured-lessor cover (AVN 67B or AVN 99) protecting the lessor’s interest against breach of warranty by the operator-lessee.
Hull deductible buy-down: secondary cover for the per-occurrence deductible under the primary hull policy, written by specialist syndicates for operators preferring to limit retained risk.
Ferry flight cover: short-period cover for delivery flights, demonstration flights or test flights, often written as a one-off endorsement to an existing policy.
A UK general aviation operator owns a 2018-build single-engine turboprop used for business travel within Europe. The aircraft has an agreed value of £2.4m. Hull all-risks cover is placed on an AVN 38B wording with a deductible of £25,000 in-motion (taxiing, take-off, landing, in-flight) and £5,000 not-in-motion (parked, towed). War risk cover is added on AVN 52E for a small additional premium. During the policy year a tow truck operator at a continental European airport mishandles a tug, causing impact damage to the aircraft’s tail. The repair cost of £180,000 is paid by the hull insurer, less the £5,000 not-in-motion deductible, with the insurer’s recovery action pursued against the airport ground handling agent under subrogated rights. Figures in this example are illustrative.
