The pilot stated that his passenger was sitting on the left hand side, and before he got out of the helicopter he asked him not to touch the controls. The pilot proceeded over to the fuel credit card system when he heard a noise. He looked behind him and the helicopter was rolling over on its side. The helicopter hit the ground and the engine stopped. The pilot asked the passenger to switch off the master switch, and then he helped him out of the helicopter.
