Probable cause
1) Incorrect control input by the student pilot and 2) the flight instructor's inadequate supervision of his student. A contributing factor in this accident was the unfavorable wind conditions.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
In his written statement, the instructor pilot stated that he and his student were practicing slope landings. He said that the left skid was against the slope and a gust of wind shifted the helicopter. He said that the student pilot did not apply the correct flight control input and the helicopter rolled over.
