Aircraft involved
Probable cause & findings
The pilot’s improper landing flare, which resulted in a hard landing. Contributing to the accident, was the flight instructor’s inadequate supervision.
Factual narrative
The flight instructor reported that, during the instructional flight practicing autorotations, the pilot receiving instruction flared the helicopter in a more pronounced nose up attitude, an aft cyclic and higher descent rate, but not excessive enough to require him to take control. During the landing, the main rotor blades contacted the tail boom. The tail rotor driveshaft and vertical fins were substantially damaged during the landing. The flight instructor reported that there were no of preaccident mechanical malfunctions or failures with the helicopter that would preclude normal operation.
