I was in a 10-person partnership with a 172. We charged a monthly rate for hangar and insurance, each member paid 10% of maintenance bills no matter how much or little they flew, and the hourly rate was just enough to cover fuel and most of the overhaul fund. In eightyears, I flew more than the other nine combined. They subsidized my flying. One partner didn’t fly once in that time, two others flew it a total of three times, one guy flew about an hour or two a month and the rest less than 10 hours a year. I was putting on two hours a week most of the time.
But…one of the guys wanted an autopilot. He convinced the majority to vote for it, so we all got to share in that bill, even though they only flew VFR day. The longest flight any of them ever took in the plane was 48 miles, twice a year. (I did fly IFR and went out of the area, but as a new instrument pilot preferrd to hand fly and build skills.)
There were also the annual that some of them helped with and left three inspection covers completely open and a total of 13 more screws not even finger tight, when they’d told me it was complete and ready for flight.
So those kind if things can happen with partners. If you have a low tolerance for wasting money on unnecessary equipment and are by-the-book with maintenance practices, you’ll need to assert a leadership position and stay in charge.
We also got boned on insurance. Because we had more than five parrtners, it was treated as a club by insurance and charged club rates. Even though we were equity partners and our rules required ownership to be PIC. As people sold over the years, they reduced it to five owners and got a reasonable price.
Weigh the options and remember that if you have more than one partner you’ll be a minority owner. There’s also availability. If you’re the only owner, you can just run out and fly whenever you want, and not have to check the schedule. I’m a sole owner now and will never go back to a partnership or club membership.
