Aero AT-3 R100, G-TGUN


After engine start the aircraft moved forward and to the left and struck a fuel bowser, despite the pilot applying pressure to the toe brakes. It is probable that the parking brake lever had inadvertently been moved to the ON position, when the pilot exited the aircraft to refuel it, without hydraulic pressure being applied to the brakes at the time. This rendered the toe brakes inoperative, and prevented the pilot from being able to stop the aircraft. The AAIB makes three Safety Recommendations addressing the parking brake system design and information provided to the pilot about its limitations.
