If an owner of a Permit aircraft formed a club, a CPL could be paid for giving taildragger tuition to qualified PPLs as long as they all belong to the club but can the owner of the aircraft be paid for the use of the aircraft?
No. The exemption in 9A 2(c) only permits aerial work, and envisages this as the instructor getting paid for the instruction. If someone pays a "hire fee" for an aircraft, other than single seaters < 910 kg, or under the exemption of chipping in to group funds as a joint owner of at least 5% of the aircraft, the flight becomes public transport for airworthiness purposes.
I can't see the point of the club exemption otherwise.
I think it envisages that the recipient of the training would be at least a joint owner. Without the exemption, they could not receive remunerated instruction in the aircraft.
