Coverage overview and quotation
Aviation insurance can include separate covers for the aircraft's physical damage, war risks, and third-party or passenger liability. Neolife prepares a submission file using aircraft and pilot details, intended use, geographical operating area, and loss history, then negotiates limits and policy terms tailored to your operation.
The four core pillars of aviation insurance
Aviation insurance is not a single product. The four core pillars must be considered together; coverage gaps and overlaps should be identified in advance.
Hull All Risks
- Sudden and accidental physical damage, excluding war
- Accident, hard landing, foreign object damage (FOD)
- Fire, water damage, storm — on the ground
- Collision — in the air and during ground movements
- Agreed value basis — total loss paid at agreed amount
- Wear and tear / improper maintenance excluded
Hull War
- Separate cover for war risks excluded from the hull policy
- War, civil war, insurrection-related damage
- Terrorism and sabotage
- Confiscation, seizure, nationalisation
- Hijacking
- Typically placed with separate London Market capacity
Aviation Liability / Combined Single Limit (CSL)
- Third-party bodily injury and property damage
- Passenger liability (per seat or within CSL)
- CSL: one unified limit — greater flexibility
- Each aircraft / any one occurrence distinction
- Cargo and mail liability
- Third-party damage on the ground around the airport
Engines & Spares Coverage
- Engines and spare parts at specified locations
- Damage to engine while running (including ground runs)
- Damage in transit
- Theft and fire — in storage
- Damage due to improper maintenance excluded
- Per-item limit determined separately
Agreed Value and limit structuring
Agreed Value — Why It Matters
Agreed Value
The insured value of the aircraft is mutually agreed between the insured and the insurer at policy inception. In the event of a total loss, this agreed amount is paid — there is no dispute over actual market value or depreciation.
ACV Is Uncommon in Aviation
The "actual market value" approach common in motor insurance is not standard in aviation. The agreed value approach eliminates value disputes at the time of loss and is preferred by lenders and financiers.
Total and Partial Loss
In the event of a total loss (aircraft destroyed or missing), the agreed value is paid. For a partial loss, repair costs are covered, but cannot exceed the agreed value. Constructive total loss (where repair cost exceeds value) is separately defined.
Agreed Value Should Be Updated
It is recommended to review and update the agreed value at each annual renewal in line with market conditions. Significant undervaluation can lead to underinsurance risk; some policies include a proportional condition for certain thresholds.
Each aircraft / any one occurrence limit distinction
Per-Aircraft Limit
In fleet policies, the hull value applicable separately to each individual aircraft. Each aircraft's value is listed in the policy; any loss is calculated against that aircraft's agreed value.
Maximum per Single Event
If multiple aircraft are affected simultaneously in a single accident event (e.g. a hangar fire), the policy's "any one occurrence" limit applies and the total indemnity is capped at that ceiling.
Combined Single Limit
A liability insurance structure that consolidates bodily injury and property damage indemnities into one unified limit rather than separate sub-limits. Provides flexibility in claim composition; the distribution is unrestricted as long as the total limit is not exceeded.
Split Sub-limits
Separate upper limits set for bodily injury and property damage respectively. Less flexible than CSL; even if claims in one category are excessive, the other category's limit cannot be used. Found in certain specialist market structures.
Each passenger sub-limit: A separate "each passenger" sub-limit may be defined within the CSL structure. This sub-limit caps the maximum liability per passenger. In commercial aviation, the Montreal Convention (MC99) and ICAO requirements set minimum liability limits; the policy limit must satisfy these requirements.
War exclusion and separate Hull War coverage
The war and similar risk exclusions in the hull policy and the separate Hull War policy must be reviewed together. AVN52E is an aviation liability extension clause; it is not the name of the hull war policy or a substitute for it. The clause version used, cancellation provisions, and geographic limits are confirmed on the quotation.
War Exclusion and Hull War Coverage
Risks excluded from Hull All Risks and those reinstated under Hull War
- War, civil war, armed conflict
- Insurrection, revolution, seizure of power
- Acts of terrorism
- Sabotage
- Confiscation, nationalisation, seizure
- Government-imposed blockade / embargo
- Hijacking
- Malicious damage — deliberate destruction
- War and armed conflict damage
- Terrorism and sabotage
- Confiscation and nationalisation
- Damage resulting from hijacking
- Damage in conditions of insurrection and civil unrest
- Malicious damage — under certain conditions
- Detonated / undetonated weapon (contested)
Geographic Operating Limits and Restricted Areas
The operating territory must be clearly defined for both the Hull and Hull War policies. If a loss occurs on a flight outside the approved operating area, coverage may be disputed. In particular:
- Hull War schedule areas: Every entry into a high war-risk area must be notified in advance to the hull war underwriter; some areas require additional premium or prior approval.
- OFAC/sanctions-list countries: In structures where US reinsurers are involved, flights to sanctioned countries create additional compliance risk.
- Arctic / oceanic routes: May require special assessment due to search-and-rescue difficulty and elevated operational risk.
Aviation War Liability (A06)
A Hull War policy covers physical damage to the aircraft itself. However, for liability arising from bodily injury to third parties or passengers during a war or terrorism event, a separate Aviation War Liability cover must be assessed. Standard liability policies exclude war; the war liability extension (e.g. AVN52E) reinstates specified risks but the scope is confirmed in each policy wording. Airlines and charter operators flying into conflict-adjacent zones should review their liability cover alongside the hull war programme.
Pilot Warranty, Approved Use, and Geographic Operating Limits
Certain conditions in aviation insurance can directly extinguish the right to a claim if breached. These must be carefully reviewed before the policy incepts.
Minimum Flying Hours
Minimum total hours required of the pilot for the aircraft type. A flight conducted below this threshold falls outside the policy's cover.
Type Rating
A valid type rating authorising the pilot to fly the specific aircraft type is mandatory.
Medical Certificate
A valid and current medical certificate (Class 1 or 2). A flight conducted with an expired medical constitutes a warranty breach.
Check Ride / Proficiency
Regular periodic proficiency checks and simulator assessments. Required as an additional condition in some policies.
Recent Experience (Recency)
Some policies define a minimum number of flying hours within a recent specified period as a warranty (recency requirement).
Listed Pilot
If a pilot not named or not meeting the criteria listed in the policy flies the aircraft, a warranty breach may arise.
Approved Use breach: Using an aircraft approved under the policy for "private use" to carry passengers for hire, operating a charter service without a charter licence, or conducting training flights outside the scope of approved use may extinguish the right to a claim. Prior agreement must be obtained from the insurer before any change in operational use.
Hull / War / Liability / Spares: which scenario, which coverage?
Understanding in advance which policy responds in a loss scenario simplifies both the negotiation phase and claims management.
| Scenario | Hull All Risks | Hull War | Liability / CSL | Spares |
|---|---|---|---|---|
| Hard landing — airframe damage | Yes | No | No | No |
| Mid-air collision with another aircraft | Hull damage | No | Third-party damage | No |
| Passenger injury — in flight | No | No | CSL / Pax Liability | No |
| Fire — post-crash | Yes | No | 3rd-party damage | No |
| Terrorist attack — bomb on board | Excluded (war excl.) | Subject to policy terms | War liability — separate assessment | No |
| Hijacking | Excluded | Subject to policy terms | War liability linked | No |
| Government confiscation / nationalisation | Excluded | Yes | No | No |
| Engine — warehouse fire | No — not in storage | No | No | Spares — in storage |
| Engine — transit damage | Marine Cargo / Spares | No | No | If transit cover included |
| Damage to third-party aircraft in hangar | No | No | General liability? No | Hangarkeeper's |
| Damage to component used in maintenance | No | No | Products Liability | Partial — wording-dependent |
| Pilot error — warranty breach | Breach — cover ceases | Breach | Breach | Breach |
| Flight outside approved use | Approved use breach | Breach | Breach | Case-by-case |
Deductible Buy-Back and supplementary covers
Main Hull Policy Deductible
In Hull All Risks policies, the deductible — the insured's own retention — varies by aircraft size and operation type. For large commercial aircraft, the deductible can represent a significant financial burden. This is the amount the insured must bear out of pocket in the event of a loss.
Deductible Buy-Back Insurance
A separate insurance that covers all or part of the deductible in the hull policy. It is purchased independently from your main hull policy. It is particularly useful for managing the cost of frequent small deductible losses in high-intensity operations and improves financial predictability throughout the year.
Additional and supplementary covers
Personal Accident Insurance (PA)
Individual accident insurance covering accidental death, permanent disability, and medical expenses. Structured separately for pilots and crew. In aviation, PA cover may be assessed independently from workers' accident or life insurance.
Ground Risk / Taxiing
Damage to the aircraft occurring during ground movements (taxiing, towing, pushback) rather than in flight. Expected to be included under Hull All Risks; however, the definition and scope of "taxiing" must be clarified in the policy wording.
Hangarkeeper's Liability
Covers damage caused to third-party aircraft taken into custody for maintenance, repair, or storage. The care, custody & control exclusion in a general liability policy does not protect those aircraft; the hangarkeeper's policy closes this gap.
Aviation Products Liability
Third-party damage arising from the failure of a manufactured or maintained part or component. Critical for aircraft manufacturers, component manufacturers, and MRO companies. The potential for a single product failure to trigger a major accident chain must be considered.
MRO Liability — Coverage Boundaries
For MRO operators, liability exposure falls into two distinct categories. Custody damage: Loss or damage to a third-party aircraft while in the operator's care for maintenance or repair — hangarkeeper's cover addresses this gap. Completed operations: Bodily injury or property damage arising from defective maintenance after the aircraft has been returned to the owner — hangarkeeper's cover does not automatically extend to this category; a specific completed operations extension in the policy wording is required. EASA Part-145 or SHGM approval scope and operational limits are factored into underwriting assessment. None of these covers are automatic; each policy wording must be reviewed separately.
Loss of Use / Business Interruption
Revenue loss resulting from the aircraft being grounded due to an insured loss. A "loss of use" limit can be structured for private aviation; a more comprehensive BI structure can be built for charter and commercial operations. Availability in the specialist market may be limited.
Hull Under Construction
Covers physical damage to an aircraft during the production process prior to first flight. Assessed for damage and transit during the period from the factory until delivery to the operator.
Ground Handling Liability
Liability arising from ramp handling, baggage loading, aircraft towing, and refuelling services carried out under a ground handling agreement (SGHA). Damage caused to third-party aircraft or equipment during handling operations falls outside the standard liability policy; a separate ground handling liability cover is required.
Airport Operators Liability
Broad liability programme for airport operators covering third-party bodily injury and property damage arising from airport facilities, runway and taxiway operations, and apron management. Distinct from airline liability; assessed separately for each airport's operational scope and passenger throughput.
Aircraft Leasing & Financing
Lessor and lender interest protections woven into the hull programme: loss payee clauses, lessor's contingent liability, breach-of-warranty endorsements, and repossession coverage. Finance parties require confirmation that their interest is noted and protected before aircraft delivery.
Pilot Loss of Licence
Provides income replacement when a pilot permanently or temporarily loses their medical certificate or flying licence due to illness or injury. Essential for self-employed pilots and operators whose revenue depends on a named aviator. Assessed on an individual basis; benefit period and waiting period are agreed at inception.
Charter Broker & Aircraft Manager PI
Professional indemnity coverage for charter brokers and aircraft management companies whose errors, omissions, or negligent advice cause financial loss to clients. Separate from the operator's own aviation liability; particularly relevant where a broker or manager arranges cover or manages fleets on behalf of aircraft owners.
Space / Satellite Adjacent Risks
Launch vehicle risks and satellite in-orbit coverage require specialist space market capacity, which is assessed separately from conventional aviation. Unmanned aerial vehicles operating above FL600 or suborbital vehicles involve a hybrid of aviation and space insurance principles; early engagement with specialist underwriters is essential.
Insurance profile by operation type
The purpose served, how the aircraft is used, and who flies it directly affects the coverage scope, premium, and warranty structure of aviation insurance.
| Operation Type | Risk Profile | Pilot Warranty Requirements | Key Considerations |
|---|---|---|---|
| Commercial Airline (AOC) | Regulated, high standards | ATPL, type rating, company check | Highest liability limits; ICAO MC99 compliance mandatory |
| Charter Operator | Varied routes, heavy utilisation | CPL/ATPL, type rating, medical | Approved use must explicitly include "charter"; route breadth important |
| Business Jet | High passenger expectations, frequent country changes | CPL/ATPL, type rating, recency | High liability limit; crew PA important; travel geography may intersect hull war schedule |
| Private Use | Low hours, varied pilot profiles | PPL/CPL, total hours, recency | No carriage of fare-paying passengers; approved use breaches are common |
| Flight Training (FTO) | Student pilot — high loss frequency | Instructor warranty separate; solo flight criteria | "Training operations" must be explicitly in approved use; touch-and-go included? |
| Air Taxi | Small aircraft, short routes, frequent take-offs/landings | CPL, type rating, medical | Passenger liability key; small aircraft crew limitations |
| Unmanned Aircraft (UAS/Drone) | Emerging market | Operator certificate (DGCA/SHGM) | Hull + 3rd-party liability; see our dedicated UAV/Drone Insurance → page |
| Air Ambulance | Night/adverse weather, emergency flights | IFR rating, night flying, medical | Medical equipment on board and medical liability should also be assessed |
| Helicopter Operations | Low altitude, rotor risk, offshore flights | CPL(H) or ATPL(H), type rating, medical | Offshore helicopter is a separate underwriting category; SAR and offshore platform operations require specialist assessment |
| Agricultural / Aerial Application | Low altitude, cable/obstacle risk | Special operations approval | Chemical damage liability risk; environmental liability may also arise |
Fleet composition and loss history: an underwriting perspective
Aviation underwriters apply standard industry risk models but assess each operator's individual profile in detail.
Fleet composition
- Aircraft type and age: Older aircraft generally carry higher loss frequency. Type certification and serial number enter the underwriting record.
- Fleet size and homogeneity: A homogeneous fleet of a single type is assessed differently from a heterogeneous fleet of mixed types.
- Engine type: Piston, turboprop, jet — each category has a distinct statistical loss profile.
- Maintenance records and certification: CAMO (Continuing Airworthiness Management Organisation) certification and compliance with current airworthiness directives.
Loss history
- Last 5–10 years: Total number of losses, total loss amount, and amounts paid are declared in detail.
- Large loss explanation: If a single loss exceeds a given percentage of the total insured value, a detailed explanation is required.
- Loss frequency: A heavy loss history leads to both premium increases and higher deductibles.
- Loss types: Pilot error, technical failure, or weather-related? Underwriters place significant importance on root cause analysis.
Loss prevention value: A robust Safety Management System (SMS), regular CRM training, near-miss reporting, and an active safety audit record create a positive impression in underwriting assessment and can provide an advantage in premium negotiations.
