Owning an aircraft and leasing it to a club to make money is only possible if you:
a) Own the aircraft entirely,
b) Own the maintenace organisation that does the maintenance,
and for an extra boost
c) Own the club that operates it.
Realistically, what can be achieved is reduction in costs. You have to be very lucky to actually make money out of owning one aeroplane. Be prepared to through piles of money into a black pit. I am not trying to disuade you, merely get accross the point that if you think you can make a profit out of one aircraft tread carefully. You can get lucky and recover some of your costs but you may suddenly find that you need to put your hand in your pocket for a new engine or a prop outside of the scheduled overhaul times.
Obviously finding the right aircraft is a task.
