NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
According to a written statement provided by the student helicopter pilot, he was practicing "sit downs and pick ups" to a grass field. The helicopter "sat down" uneventfully and the student pilot reduced power to chat with a friend. Shortly thereafter, the student pilot added power, ensured that all engine instruments were in the green, and attempted a takeoff. The student pilot detected a tailwind and applied left pedal correction; however, the helicopter yawed to the right one full rotation before the student pilot was able to set the helicopter back down. During the hard landing the horizontal stabilizer was bent, both tail rotor blades were damaged, the tail boom was wrinkled, and the fuselage was wrinkled on the right side. An examination of the helicopter and its related systems, conducted by a Federal Aviation Administration inspector, revealed no preexisting anomalies.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The student pilot's failure to maintain control of the helicopter during takeoff, resulting in a loss of tail rotor effectiveness and a subsequent hard landing. Full narrative available
