someone at the caa is bull****ing you !! If they could make a case they would have done many years ago . The fact that they have known about the leasing of aircraft for the last 20+ years would make it impossible for them to suddenly jump up and try to stop it . People have proved over all these years that it is a)safe and b) legal and not to mention that suddenly it would effectively be P.Transport to hire a plane for hour building , all club flying would then also be P.T. and what if your heli was in for service does that mean you cannot hire one and fly it yourself???what if you are ill and feel unsafe to fly or the weather becomes poor and you get a pilot to fly you home , would that be P.T?? No, how could it be ? If the aircraft is then NOT on anyones aoc it cannot be flown back by anyone !!!! The fact is that you have to have a lease agreement ,make sure the customer understands the difference between a P.T flight and a lease, the and that is the sum of your involvement . You do not supply and pay the pilot because then you are making a service and then it is P.T. Having said that if joe bloggs just phoned up wanting a ride from a to b i would do it as an aoc charter . Lease work is done mostly on a bundle of hours . In my correspondence with the caa they reiterated that my only responsibility was the heli maintained to P.T cat and the responsibility for the flight being done within rules was with the operator.
