Rotorsport UK MTOsport, G-PAFF

Summary:

The pilot had just landed from a previous flight and repositioned the aircraft for an immediate takeoff. As he pulled the control column back and advanced the throttle he felt a heavy jolt through the controls. He immediately aborted the takeoff and stopped the aircraft to assess the situation. It became clear that the rotor blades had struck and damaged the top of the rudder. The rotor strike was caused by an excessive rearward tilt of the rotor disc, due to insufficient rotor speed combined with the acceleration of the aircraft.
