Incident Overview
A helicopter sustained damage during a training flight that involved a practice autorotation. The purpose of the flight was to provide instruction to a foreign national who held a U.S. private helicopter rating. The certified flight instructor (CFI) reported that during the maneuver, as the helicopter descended through approximately 50 feet above ground level (AGL), he announced twice for the student to flare.
Sequence of Events
When the expected flare did not occur, the CFI took control of the helicopter and initiated a power recovery. However, evidence indicates that the helicopter touched down in a nose-high attitude. Following the touchdown, the main rotor blades contacted the tail boom. The helicopter came to rest 138 feet from the point where it first touched down.
Damage and Findings
The accident resulted in damage to the helicopter, specifically from the main rotor blade striking the tail boom. The source does not specify the extent of damage or any injuries. No other details about the aircraft, location, or weather conditions were provided.
