I own a C172 which I leae back to my local flying club. But primarily I do it for business rather than making it available to me whenever i want it.
If I want it, I have to book it like any other club member. What's more, to keep Her Majesty's Esteemed (spit) Tax Inspectors off my back, I insist on paying club rates for it so I cannot be accused of getting a benefit in kind.
I've heard horror stories about that (like demands for £25k on the basis of an a/c being available to fly for so many hours a year - nothing to do with actual hours flown by the owner).
It works out OK - the aircraft is only available to PPLs with over 100 hrs experience (not because its a complex type but because it keeps my insurance bill manageable). This means it's not getting hammered every hour of the day, and when I want to book it it's usually available at a few day's notice.
It doesnt make me a fortune but it does pay for itself & it helps the club.
