Most owners read the hull value and liability limit on their policy, then stop. The smaller lines underneath are where surprises tend to show up after a loss. Pilots compare these details all the time online: foam, search and rescue, extra expense, hangar liability, and separate deductibles for in motion and not in motion. If you own your aircraft, those lines deserve ten minutes of your attention.
What a sub-limit actually is
A sub-limit is a cap on one specific type of loss inside your policy. Your hull may be insured for the agreed value, yet a particular extra may only pay up to a smaller amount. These numbers differ from one policy to the next, so your declarations page matters more than any rule of thumb.
Extras worth finding on your policy
Not every policy includes all of these, and the amounts vary. Look for each one by name:
- Search and rescue or recovery costs: the expense of locating or retrieving an aircraft after an accident.
- Wreckage removal and cleanup: including items like foam or debris removal after a loss.
- Extra expense or loss of use: costs that can come up while your aircraft is out of service.
- Hangar liability: relevant if you damage someone else's aircraft in a hangar you rent.
- Personal effects and ground equipment: headsets, tablets, tow bars and similar gear.
- Medical payments: often set per seat, so check how it is written.
Check both deductibles
Many hull policies use one deductible while the aircraft is in motion and another when it is not in motion. A hangar bump and a hard landing can be treated differently, so read both figures before you compare quotes.
A simple way to review your policy
Compare quotes line by line, not by total premium alone. Ask which extras are included, which are optional, and what each one pays up to. Keep a copy of the declarations page where you can find it quickly. If your needs change, such as a new single-engine aircraft insurance policy after buying a different plane, review these lines again rather than assuming they carry over.
Wording and availability depend on the insurer and your policy terms. For a broader look at what is covered, see our guide to aircraft insurance, or get a quote from SkyWatch and ask us about the extras you care about.
FAQ
What is a sub-limit in aircraft insurance?
It is a cap on a specific type of loss within your policy, often lower than your hull value or liability limit.
Where do I find my sub-limits?
Start with your declarations page and any endorsements. If a line is unclear, ask your insurer to explain it in writing.
Does my policy cover search and rescue costs?
Some policies include it, often with a cap. Check the policy wording to see whether it applies and how much it pays.
Are in motion and not in motion deductibles the same?
Not always. Many policies list separate amounts, so confirm both.
Should I choose a policy by premium alone?
No. Compare included extras, limits and deductibles as well, since two similar premiums can cover different things.
