Probable cause
The pilot’s loss of control after takeoff for reasons that could not be determined based on the available information.
NTSB analysis
The pilot was performing an annual inspection and maintenance flight for the helicopter at the time of the accident. After the pilot completed three or four short flights prior to attempting an additional flight. During this flight, the helicopter was exiting translational lift when it dipped and turned right abruptly and hit the ground. Postaccident examination of the helicopter confirmed flight control continuity. Additional examinations of the engine were limited due to damage incurred from impact damage and postimpact fire. The reasons for any loss of control and/or engine failure could not be determined.
There was no available evidence that a medical factor contributed to the crash.
