Owning or operating a private aircraft is, by most measures, the most complex personal insurance challenge in the HNW market. Aviation is a highly regulated industry, and aircraft insurance reflects that complexity: the policy wording draws on decades of Lloyd's market precedent, international convention, and specific regulatory requirements that differ markedly from any other class of personal insurance. A significant claim on an inadequately placed aviation policy can have ruinous consequences — not just financially, but potentially in terms of criminal and regulatory exposure.
This guide explains the core components of private aviation insurance, the critical policy terms that owners frequently misunderstand, and how the market operates.
Hull Insurance: Agreed Value and Why It Matters
The foundation of any aircraft policy is the hull all risks section, covering physical loss or damage to the aircraft.
As with marine insurance, the valuation basis is critical. Agreed value policies pay the declared sum insured in the event of a total loss, without reference to market value or depreciation. For private aviation, agreed value is the industry standard and should be treated as non-negotiable.
However, how agreed value is established matters enormously. Aircraft values are affected by:
- Log book hours — high-time airframes and engines reduce value
- Airworthiness directives (ADs) — outstanding or recently completed ADs affect value and insurability
- Maintenance status — aircraft on approved maintenance programmes (e.g. through an approved Part 145 maintenance organisation) command better terms
- Avionics upgrades — a recently refurbished flight deck can significantly increase agreed value
- Completion standard — for business jets, interior specification heavily influences value
Depreciation methodologies differ between insurers. Some insurers will apply a stated value approach, in which the scheduled value in the policy reduces annually whether or not there has been a loss. Others will update the agreed value annually at renewal. It is worth confirming how your policy treats the agreed value over time and ensuring it remains aligned to the actual market value of the aircraft.
Aviation Liability: Third-Party and Passenger Cover
Aviation liability insurance covers your legal liability to third parties — both on the ground and in the air. It is conceptually similar to motor liability, but the scale of potential liability is vastly greater.
The main components are:
Third-party bodily injury and property damage — covers liability to people and property on the ground or in the air (other than passengers on board). In most cases, aviation liability limits are expressed as a combined single limit (CSL) — one overall figure applying to any single occurrence.
Passenger liability — covers liability to passengers aboard the aircraft in the event of injury or death. Depending on the jurisdiction in which you are operating, different international conventions apply:
- Warsaw Convention — older regime, lower liability caps
- Montreal Convention 1999 — the modern framework, unlimited liability in practice (strict liability up to a threshold, fault-based above it), applicable in the UK, EU, US, and most major aviation jurisdictions
Minimum liability limits for private aviation vary by aircraft type and jurisdiction. For a light piston aircraft operating domestically, £1–2 million per occurrence may be technically adequate. For a business jet carrying passengers internationally, minimum third-party liability limits of $50–$100 million per occurrence are typical — and some airports or territories require evidence of specified minimum cover before operating. Confirming applicable minimum requirements for every territory in which you intend to operate is essential.
Open Pilot Warranty vs Named Pilot Warranty
One of the most consequential terms in any private aviation policy is the pilot warranty — the clause defining who is permitted to fly the insured aircraft with the policy in force.
Named pilot warranty — only specifically named individuals, listed in the policy, are permitted to act as pilot-in-command (PIC). This is straightforward but inflexible. If a named pilot is unavailable and you need a ferry pilot or substitute, you must notify the insurer in advance.
Open pilot warranty — permits any pilot meeting defined minimum qualifications to fly the aircraft. A typical open pilot warranty might require the PIC to hold:
- A current CPL or ATPL with appropriate class/type rating
- A minimum number of total flying hours (e.g. 500 hours total time)
- A minimum number of hours on type or similar type (e.g. 100 hours on type)
- A current class medical
If the aircraft is flown by a pilot who does not meet the warranty conditions — even inadvertently — the policy may be void for that flight. Pilots must be checked against warranty conditions before every flight where there is any doubt.
Owner-pilot considerations — where the aircraft owner is also a qualified pilot but not a professional aviator, underwriters will scrutinise total hours, recency, and type currency carefully. Inadequate recency can result in the underwriter requiring a named pilot warranty rather than an open warranty, limiting flexibility.
War, Terrorism, and AVN48
Standard aviation policies contain war exclusions — aviation hull and liability cover does not extend to losses caused by war, invasion, acts of foreign enemies, rebellion, revolution, insurrection, or seizure by governments.
The war exclusion in aviation is expressed through the AVN48 endorsement (and its successor, AVN52, for liability). These are market-standard clauses developed by the London market, and they are virtually universal.
Separate war and allied perils cover (sometimes called AVN52 cover) can be purchased to reinstate this excluded exposure — covering hull and liability losses arising from war, hijacking, and terrorism. This cover is essential for any aircraft operating in regions of elevated geopolitical risk, and many finance agreements for aircraft purchases require evidence that war risk cover is in place.
Cover under AVN48/52 can be cancelled at seven days' notice by underwriters in the event of a deterioration in the risk environment. This is a feature of the war risk market: if a new conflict erupts, insurers may cancel war risk cover across affected territories at short notice.
Hangarkeeper's Liability
If you share a hangar with other aircraft owners, or if your FBO or maintenance provider stores your aircraft in a shared facility, hangarkeeper's liability becomes relevant. This cover protects you against liability for damage to third-party aircraft in your care, custody, or control — for example, if your aircraft accidentally damages an adjacent aircraft in the hangar.
Equally, if you operate a hangar and store others' aircraft within it (even informally), you may have a hangarkeeper's liability exposure that requires its own cover.
Loss of Licence: The Owner-Pilot Risk
For owner-pilots who fly their own aircraft, the ability to fly is linked to holding a current medical certificate. Loss of that medical certificate — due to cardiovascular disease, neurological conditions, diabetes requiring insulin, or a host of other medical grounds — means the pilot can no longer legally fly as PIC.
Loss of licence insurance pays a capital sum or regular income benefit in the event that the insured pilot permanently loses their licence on medical grounds. This is conceptually similar to critical illness or income protection insurance, but calibrated for the aviation industry.
For an owner who flies purely for pleasure, loss of licence has lifestyle consequences but may not have a direct financial impact (unless the aircraft is maintained specifically for owner use and will be sold or chartered if the owner cannot fly it). For owner-operators whose business activities depend on their ability to fly, the income consequences can be material.
AOC Operations vs Private Operations
A critical distinction in aviation insurance is between Air Operator's Certificate (AOC) operations and private (non-commercial) operations.
Private aviation under a private pilot's licence or PPL/IR is regulated differently from commercial air transport. The policy wording — particularly for liability — differs significantly between the two:
- Private non-commercial operations: the aircraft is flown for the owner's personal use, without charge to passengers
- AOC commercial operations: the aircraft is operated for hire and reward under an AOC issued by the relevant national authority (CAA in the UK, EASA members within the EU)
If you occasionally charter your aircraft (receiving payment for carriage), you are operating commercially — whether or not you have an AOC. Operating without the correct approvals and without the correct insurance to match invalidates your policy and, more critically, exposes you to regulatory sanction.
Jet card and fractional ownership arrangements occupy a different position: when you purchase a jet card or fractional share, the operator (the card/fractional company) bears the insurance obligation. Your risk transfer is to the operator, not to a hull and liability policy of your own. Understanding the insurance limits and carrier quality in these arrangements is important before committing significant capital.
Key Specialist Underwriters
The private aviation insurance market is concentrated in specialist hands:
- Global Aerospace — one of the leading global aviation insurers, writing hull and liability across all aircraft categories
- AIG Aviation — long-established in the US and international private aviation market
- Starr Aviation — competitive across owner-flown turbine, light and heavy aircraft, and helicopter risks
- Allianz Commercial (the former Allianz Global Corporate & Specialty, AGCS) — one of the largest aviation insurers globally

For any aircraft with an insured hull value above approximately £1 million, or carrying passengers regularly, using a specialist aviation broker rather than a general personal lines broker is strongly advisable.
Practical Checklist for Aircraft Owners
Before binding or renewing aviation cover, confirm:
- The hull is insured on an agreed value basis with a value aligned to current market
- Liability limits are adequate for the jurisdictions in which you operate — confirm minimum requirements for US, EU, and Middle East operations if relevant
- The pilot warranty conditions are clearly understood and complied with by all pilots
- War and allied perils cover is in place, particularly for international operations
- Commercial or charter use is explicitly covered if applicable
- Hangarkeeper's liability is included if relevant
- All maintenance and airworthiness obligations are up to date — unairworthy aircraft face policy avoidance risk
