NTSB Final Report: Rotorway Exec
Failure To Maintain Lateral Control Of The Helicopter During Takeoff, Which Resulted In A Dynamic Rollover Analysis: The non-certificated pilot of the helicopter reported that the purpose of the flight was to practice takeoff, hover, and landing maneuvers from his private grass field. During takeoff, he increased the engine power and inadvertently applied right cyclic concurrently as he raised the collective. Subsequently, the helicopter’s right skid dug into the ground, resulting in a dynamic rollover.
