Probable cause
Pilot's remedial actoin after encountering a pitch up wass too abrupt and the improper use of the cyclic control.
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
While crossing over a ridge line the plt reptd that the helicopter pitched up, then down, followed by a violent right turn. The plt was able to arrest the turn but the helicopter was too low to the downward sloping ridge and a crash was imminent. The plt executed a left pedal turn to collide with the terrain to the left which would prevent the helicopter from rolling downhill. The wreckage examination disclosed no evidence of any preimpact malfunctions and/or failures in the flight control system.
