ROBINSON R-22B
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.
PILOT'S REMEDIAL ACTOIN AFTER ENCOUNTERING A PITCH UP WASS TOO ABRUPT AND THE IMPROPER USE OF THE CYCLIC CONTROL.
