Aircraft Insurance Coverage Options Above the Lender Minimum: How to Choose
This guide is for owners, financed or not, who have met the lender's insurance checklist and now need to decide what to buy on top of it. Each section explains one coverage choice and gives a rule for deciding.
What does the lender minimum leave open?
A lender typically specifies agreed-value hull coverage, loss-payee and breach-of-warranty endorsements, a cancellation notice and a liability minimum. Our aircraft loan insurance requirements guide covers that checklist in detail. What the lender usually doesn't specify is how the liability limit is structured, who beyond you may fly, what happens while the aircraft sits in a shop, or anything that protects your passengers, your hangar or your schedule. Those are your decisions.
Smooth vs sublimited liability: which should you choose?
Liability coverage pays for bodily injury and property damage you cause to others, including your passengers. It comes in two structures:
- Smooth (no passenger sublimit): "the full policy limit applies to any claim, regardless of how many passengers are involved" (BWI, Mar. 2026). AOPA describes smooth limits as "the removal of the passenger sublimit" (AOPA).
- Sublimited (per-passenger): the policy has a total limit, but each passenger is capped at a lower figure. BWI's examples are $100,000 or $250,000 per passenger under a $1,000,000 total.
Here is what that means in a single accident, comparing a $1,000,000 smooth limit with $1,000,000 and a $100,000 per-passenger sublimit:
| Passengers injured | $1,000,000 with $100,000/passenger | $1,000,000 smooth |
|---|---|---|
| 1 | $100,000 total, at most $100,000 each | Up to $1,000,000 shared as needed |
| 2 | $200,000 total, at most $100,000 each | Up to $1,000,000 shared as needed |
| 3 | $300,000 total, at most $100,000 each | Up to $1,000,000 shared as needed |
| 4 | $400,000 total, at most $100,000 each | Up to $1,000,000 shared as needed |
A single seriously injured passenger can exceed a $100,000 sublimit on their own, and whatever the policy doesn't pay is your problem. AOPA notes that "many times, a smooth policy is only a few hundred dollars more than a sublimit policy."
Decision rule: if you ever fly with passengers, choose smooth limits. A sublimited policy only makes sense if you fly solo nearly all the time, and even then, check that the price difference is worth giving up the flexibility.
How much liability limit is enough?
Lenders often require $1,000,000 per occurrence. That is a minimum for the lender, not a recommendation for you. Size the limit around three questions:
- How many seats do you fill? A four-seat aircraft carrying family on most trips has more exposure than a solo commuter.
- What would a claimant pursue? Home equity, investments and business interests are exposed above your policy limit.
- What does the next step up cost? BWI says increasing liability from $1,000,000 to $2,000,000 "often costs far less than owners assume". Get the quote before deciding.
Don't count on a personal umbrella policy to sit on top of aircraft liability. Many umbrella policies exclude aircraft. Read the exclusions, or ask your umbrella carrier in writing, before relying on one.
Open-pilot or named-pilot warranty?
The pilot warranty decides who is covered at the controls. A named-pilot warranty lists specific people, each with their own requirements. An open-pilot warranty covers anyone who meets written minimums. An illustrative clause might read "any private pilot with at least 500 total hours and 25 hours in make and model"; your policy's actual numbers will differ.
| Situation | Better fit | Watch for |
|---|---|---|
| Sole owner, only you fly | Named pilot | Add your CFI by name if they'll fly the aircraft without you |
| Partnership or co-ownership | Named (each partner) or open-pilot | The least experienced partner often drives the price; see co-ownership agreements |
| Family members or friends may fly | Open-pilot with minimums they actually meet | Verify each person's hours against the clause before they fly |
| Shop or ferry pilots move the aircraft | Either, with a mechanic or ferry-pilot provision | Ask how the policy treats taxiing by a mechanic and ferry flights |
Being named on the policy isn't the same as being covered. A named pilot who falls short of their listed requirements, such as a missed recurrent training event, is flying outside the warranty. On a financed aircraft, that is exactly the breach the lender's endorsement exists to protect the lender from, while leaving you unprotected.
Hull options: agreed value, ground and flight, or not in motion
Financed aircraft carry all-risk ground and flight hull coverage on an agreed value basis. Beyond that, a few choices are worth knowing:
- Not in motion (ground-only): covers the aircraft while parked, hangared or tied down, but not while taxiing or flying. It costs less, which makes it useful during a long layup, restoration, or engine overhaul. On a financed aircraft, get the lender's written consent before switching, and put ground-and-flight coverage back in force before anyone taxis.
- Agreed value after upgrades: an avionics upgrade or overhaul raises value. Endorse a higher agreed value, or a total loss pays the old number.
- Component sublimits: some policies limit payouts for specific components or equipment. If you have high-value avionics or a fresh engine, ask whether any sublimit applies.
How should you choose a deductible?
Hull deductibles are usually split: an in-motion deductible for taxi and flight losses, and a lower or zero not-in-motion deductible for losses while parked. Some policies express the in-motion deductible as a percentage of hull value. A higher deductible lowers the premium, but it has to be paid in cash at the worst possible time.
Worked example, using two hypothetical quotes for the same aircraft (ask your broker for real pairs):
| Quote | In-motion deductible | Annual premium |
|---|---|---|
| A | $1,000 | $1,900 |
| B | $5,000 | $1,700 |
Quote B saves $200 a year but adds $4,000 of exposure per claim. Break-even: $4,000 ÷ $200 = 20 claim-free years. With a break-even that long, the lower deductible is the better buy. A higher deductible makes sense when the saving pays back in a few years and the deductible is easy to cover from reserves. Before choosing, check your loan agreement, because some lenders cap the hull deductible on financed aircraft.

Which smaller coverages are worth adding?
Hangar-keepers liability
Covers damage to other people's aircraft while they are in your care, custody or control. It matters if you own a hangar and store a partner's or friend's aircraft, sublease space, or operate a shop or FBO. Your own aircraft policy doesn't extend to aircraft you don't own. If you own the hangar building, also ask about premises liability and property coverage. If you rent a hangar, read the lease: many set their own insurance requirements for tenants.
Medical payments
Pays medical expenses for occupants after an accident regardless of fault, usually with a per-seat limit. It is not a substitute for liability coverage, but it lets you help an injured passenger quickly without a claim against you. Limits and pricing vary by carrier, so ask what is offered.
Loss of use
Reimburses the cost of renting a substitute aircraft while yours is being repaired after a covered loss, usually subject to a daily rate and a maximum. It is most useful if your business travel depends on the aircraft, or rentals near you are scarce.
Non-owned aircraft coverage
Your policy covers your aircraft. If you also rent, borrow, or fly club aircraft, you need non-owned (renter's) coverage to protect yourself. Some carriers add it as an endorsement; others sell it separately.
Territory and other endorsements
Confirm the policy territory covers everywhere you plan to fly, especially trips outside the United States. Ask about personal effects, and any other endorsement relevant to your mission, before the trip rather than after.
How to decide: match coverage to how you fly
| If you… | Consider | Why |
|---|---|---|
| Carry family or friends | Smooth liability, higher limit | Per-passenger caps can leave a single injured passenger undercompensated |
| Have significant personal assets | $2M+ smooth limit | Assets above the limit are exposed; the step up is usually inexpensive |
| Share the aircraft | Open-pilot or every pilot named | An uncovered pilot is a warranty breach |
| Face a long overhaul or restoration | Not-in-motion hull for the layup, with lender consent | Saves premium while nobody flies |
| Own a hangar or store others' aircraft | Hangar-keepers and premises liability | Your aircraft policy doesn't cover aircraft you don't own |
| Also rent or borrow aircraft | Non-owned coverage | Your policy follows your aircraft, not you |
| Rely on the aircraft for work | Loss of use | Rental reimbursement while yours is repaired |
| Keep thin cash reserves | Lower in-motion deductible | The deductible is due when cash is tightest |

Frequently asked questions
What is the difference between smooth and sublimited aircraft liability?
A smooth limit makes the full liability limit available for any covered occurrence, however many passengers are hurt. A sublimited policy, such as $1,000,000 with $100,000 per passenger, caps each passenger at the sublimit. With four injured passengers, that policy pays passengers at most $400,000 in total. AOPA notes smooth coverage is often only a few hundred dollars more.
What is an open-pilot warranty on an aircraft policy?
An open-pilot warranty covers any pilot who meets the minimum qualifications written in the policy, such as a certificate level, total hours and hours in make and model, without naming each person. It suits partnerships, clubs and families. The alternative is a named-pilot warranty that lists specific people. Either way, anyone who flies outside the warranty creates a breach.
Can I switch a financed aircraft to not-in-motion coverage during a long annual?
Sometimes, but only with the lender's written consent. Not-in-motion (ground-only) hull coverage is cheaper because it excludes taxi and flight, and it can suit a long layup, restoration or engine overhaul. Most loan agreements require ground-and-flight coverage, so get lender approval first and reinstate full coverage before anyone taxis the aircraft.
Do I need hangar-keepers liability insurance?
Only if you have other people's aircraft in your care, custody or control, for example if you own a hangar and store a partner's or friend's aircraft, or run a shop or FBO. Your own aircraft policy covers your aircraft, not someone else's. If you own the hangar itself, also ask about premises liability and property coverage for the building and contents.
How much liability coverage should a piston aircraft owner carry?
Lenders often require $1,000,000 per occurrence, but the right number depends on how often you carry passengers and what you have to protect. Many owners who fly family or friends choose a smooth limit of at least $1,000,000, and consider $2,000,000 or more with significant assets. BWI says raising limits from $1M to $2M often costs far less than owners expect.
Should I choose a higher deductible to lower my aircraft premium?
Only if the premium saving pays back the extra exposure within a reasonable number of claim-free years, and you can pay the deductible from cash without strain. Divide the extra deductible by the annual saving to find the break-even period. Check your loan agreement first, because some lenders cap the hull deductible on financed aircraft.
