Named pilots versus open pilot
Two structures matter for shared aircraft.
A named-pilot policy lists each covered pilot individually. The insurer underwrites each person's hours, ratings and experience. Premiums reflect the actual group, and a low-time partner materially raises the cost — sometimes by more than they expect, which is a conversation worth having before they join rather than after.
An open-pilot warranty covers anyone meeting stated minimums: total time, time in type, tailwheel or complex time, instrument currency. More flexible, and dangerous if the group does not police it. Fly outside the warranty and you are effectively uninsured for that flight — a fact partners discover at the worst possible moment.
For a small partnership, named-pilot is usually right: everyone is known and the cover is certain. Clubs generally need an open-pilot warranty because the membership changes.
Read the warranty as a rule, not a formality
If your policy requires 25 hours in type and a partner has 18, they are not covered, regardless of how competent they are. If it requires a checkout with a CFI every 12 months and someone is at 14 months, same answer.
Put the warranty minimums in the operating agreement, and make somebody responsible for tracking currency. This is dull and it is the difference between an insured incident and a personal financial catastrophe.
Hull cover: agreed value, and getting it right
Most GA hull policies are agreed value — you and the insurer fix a figure and that is what is paid on a total loss. Two failure modes:
Insuring too low to save premium. If the aircraft is worth $88,000 and insured for $65,000, a total loss leaves the partnership $23,000 short of replacing it, and that shortfall is split between people who now have no aeroplane.
Failing to update after upgrades. A $30,000 panel upgrade raises the aircraft's value. If the agreed value has not moved, you have paid for avionics you are not insured for.
Review the agreed value annually and after any significant work. It is a five-minute call.
Splitting the premium
Insurance is a fixed cost and should be split like other fixed costs — equally where ownership is equal, by share where it is not.
The complication is when one partner materially raises the premium. A 90-hour partner joining a group of 1,000-hour pilots might add $600 a year. Three defensible approaches:
- Absorb it. Everyone benefits from having a partner, the cost is shared. Simple, and fine if the difference is modest.
- Surcharge the difference. Ask the insurer for a quote with and without that pilot; the difference is theirs. Precise and transparent — and it does put a price on someone's inexperience, which needs handling with some care.
- Taper it. The surcharge applies until they reach the hours where the premium normalises. Rewards them for building time and has a defined end.
Whichever, agree it before they join. Presenting a surcharge to someone who has already bought in is a poor start.
Who pays the deductible
Almost always the pilot who was flying. This is standard, it is defensible, and it needs writing down, because the alternative — splitting it — means careful partners subsidise careless ones.
Deductibles on a piston single commonly run $500 to $2,500 for in-motion damage, often less or nil for not-in-motion. Make sure every partner knows the figure, because a $2,500 deductible changes how someone thinks about a marginal crosswind.
Two edge cases to settle in advance: damage discovered with no known cause — usually shared as a group cost, since blaming someone without evidence poisons everything — and damage while a non-partner CFI was flying, where the answer depends on your policy and should be checked with the broker rather than assumed.
What actually reduces premiums
- Hangar rather than tie-down, sometimes materially
- Recurrent training, formal type-specific courses count for more than a flight review
- Instrument ratings across the group
- Hours in type — the single largest factor for a low-time pilot
- A clean claims history, which is why small damage is often better absorbed than claimed
