How much does it cost to co-own an airplane?

Co-owning an airplane typically costs 40-60% less per partner than sole ownership. Fixed costs like hangar, insurance, and annual inspection are split equally, while variable costs like fuel and engine reserves are paid based on hours flown. For a Cessna 172, a 2-partner arrangement can reduce each partner's annual cost from ~$25,000 to ~$15,000.

How do you split costs in an aircraft partnership?

The most common approach is to split fixed costs (hangar, insurance, annual inspection, misc) equally among all partners, and split variable costs (fuel, oil, engine reserve) based on each partner's actual flight hours. Some partnerships use a flat equal split or custom percentages instead.

What are the downsides of an aircraft partnership?

The main downsides are scheduling conflicts (especially on weekends and holidays), disagreements on maintenance decisions or upgrades, unequal wear and tear, and the complexity of a partnership agreement. A well-drafted co-ownership agreement covering scheduling, maintenance standards, buyout terms, and dispute resolution can mitigate most issues.

How many partners should an aircraft partnership have?

Most aircraft partnerships have 2-4 partners. Two partners offer the best balance of cost savings and availability. Three partners save more but require more scheduling coordination. Four partners maximize savings but can create frequent scheduling conflicts, especially if partners fly more than 75-100 hours per year each.

How Aircraft Partnerships Work

An aircraft partnership (or co-ownership) is when two or more pilots share the cost and use of an airplane. Fixed costs like hangar rent, insurance, and annual inspections are split equally among partners, while variable costs like fuel and engine reserves are typically paid by whoever flies the hours. This arrangement can reduce each partner's annual cost by 40-60% compared to sole ownership.

Fixed vs. Variable Costs

Understanding the split between fixed and variable costs is key to evaluating a partnership:

Fixed Costs (Split Equally)

Hangar or tiedown rent
Hull and liability insurance
Annual inspection
Registration, taxes, and miscellaneous

Variable Costs (By Hours Flown)

Fuel (based on burn rate)
Oil consumption
Engine overhaul reserve
Unscheduled maintenance

Tips for a Successful Partnership

Draft a written agreement covering scheduling, maintenance standards, buyout terms, and dispute resolution.
Use an online scheduler (Google Calendar, Coflyt, or SchedulePointe) so everyone can see availability.
Set a shared maintenance fund that each partner contributes to monthly, so big expenses don't come as a surprise.
Agree on minimum insurance requirements and pilot currency standards before buying.
Include a right of first refusal clause so remaining partners can buy out a departing partner before the share goes to a stranger.

Partnership agreements should be reviewed by an aviation attorney. Always consult qualified professionals before entering a co-ownership arrangement.
