Tampering with parked aircraft
One of our pilots returning to the aircraft at Rottnest today found that it had been moved off the bitumen parking area and pushed onto a soft surface not meant for parking. A bunch of people doing a club activity were witnessed moving aircraft around and decided to just push it out of their way so they could occupy the parking space instead and box him in. Good thing people take so many photos these days....
Pilot needed assistance to get the aircraft back to a solid surface where he could start the engine without damaging the (brand new) prop..
So, I know there are rules about tampering with aircraft, any ideas where I can find them?
