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
The helicopter made a hard landing after the pilot experienced a power train failure while flying low and slow. The weather was VMC and a VFR flight plan was filed. The crew was searching for lost mining equipment in a low slow search pattern. The pilot heard the engine out audio in his head set as he was looking out. He managed to avoid trees while descending but made a hard landing on a steep slope and the helicopter rolled over.
