Most pilots spend time shopping for the right aircraft insurance premium. Far fewer spend time reading what the policy won't cover. That gap matters more than you'd think. Policy exclusions are where claims get denied, and where owners discover their coverage wasn't quite what they assumed.
This isn't about scaring you off from buying aircraft insurance. It's the opposite. Understanding your exclusions puts you in a better position to buy coverage that actually holds up when you need it.
Hull exclusions most owners miss
Hull coverage gets the most attention because it protects the aircraft itself. But standard hull policies come with exclusions that catch people off guard.
Wear and tear is almost universally excluded. If your engine has accumulated cycles, your brakes are worn, or your avionics are aging, those aren't covered losses. Insurance pays for sudden, accidental damage, not gradual deterioration.
Mechanical or electrical breakdown falls into the same category. An engine that quits due to an internal failure is not a covered hull claim in most policies. If the same engine is damaged in a subsequent forced landing, the hull damage from the landing itself may be covered, but the engine failure that caused it won't be.
Unapproved modifications are another one. If you've made changes to your aircraft that weren't done under FAA-approved data or a proper STC, your insurer may have grounds to contest a claim that involves those modifications. Worth knowing before you do the work.
When your pilot certificate can void coverage
Aviation policies are built around pilot qualifications. Most policies include what's called a pilot warranty or pilot clause. It states that the aircraft will only be operated by pilots who meet specific minimums. Those minimums vary by policy, but commonly include total hours, hours in make and model, and ratings held.
If someone who doesn't meet those minimums flies the plane, even with your knowledge and permission, coverage can be voided entirely. This applies to hull and liability. It's one of the more serious exposures that single-engine aircraft owners can face when they allow a friend or family member to fly without checking the policy first.
Currency is a related issue. Some policies require the named pilot to be current under FAR 61.57 at the time of an incident. If your medical lapsed, if you haven't done your three takeoffs and landings in the last 90 days, or if you're outside your instrument currency when you file IFR, your insurer may argue there was a policy violation at the time of the loss.
Intentional acts and illegal use
This one is straightforward but worth stating. Policies exclude coverage for intentional damage and for aircraft used in furtherance of illegal activity. Operating under the influence, conducting Part 135 operations without the appropriate certificates, or transporting contraband would all fall into this territory. The exclusion extends to liability as well, so a third party injured during illegal operations would not be covered by your policy.
War and government seizure
Standard aviation policies exclude loss caused by war, invasion, civil war, military action, or government seizure. War risk coverage is available as a separate endorsement, but it's not included in a standard aviation insurance policy. For most domestic flying, this exclusion never comes into play. If you're flying internationally, it's worth knowing it exists.
How to actually use this information
The best time to read your exclusions is before a claim, not during one. Pull out your declarations page and find the exclusions section. If anything isn't clear, call your broker and ask them to explain it in plain language. Ask specifically: what would cause a claim to be denied? What pilot qualifications does this policy require? What modifications would void coverage?
If you're shopping for new coverage, use this framework to compare policies. Two policies at the same price point can have meaningfully different exclusions. The right question isn't just what's covered; it's what's not.

Frequently asked questions
Does aircraft insurance cover engine failure?
Usually not as a standalone mechanical event. Most hull policies exclude mechanical and electrical breakdown. If the engine failure leads to an accident and the airframe sustains damage in that accident, the hull damage from the impact may be covered. The engine failure itself typically is not.
What happens if I let a friend fly my plane and they have an accident?
It depends entirely on whether that friend meets the pilot qualifications specified in your policy. If they don't, your insurer may deny the claim entirely. Before allowing anyone else to fly your aircraft, check your policy's pilot clause. Some policies use an open pilot warranty that allows any pilot meeting broad minimums. Others name specific pilots.
Can my insurance be voided if I'm not current?
Some policies do include currency requirements. If your policy specifies that the pilot must be current per FAR 61.57 and you're not at the time of a loss, your insurer may use that as a basis to contest the claim. Read your policy language carefully and ask your broker to clarify what currency means under your specific policy.
Does my policy cover an aircraft I borrowed from someone else?
Not under your owner's policy. Owner policies follow the aircraft you own. If you fly a borrowed or rented aircraft without being listed on that aircraft's policy, you'd need aircraft renters insurance to cover your liability exposure.
What is a pilot warranty and why does it matter?
A pilot warranty is a clause in your policy that defines who is authorized to fly the insured aircraft. If anyone flies the aircraft who doesn't meet those requirements, the insurer can treat it as a policy violation and deny coverage. It matters because violations don't require bad intent. Even well-meaning situations, like letting a less-experienced friend build hours, can expose you to a coverage gap.
