NTSB Narrative Summary Released at Completion of Accident
THE ACFT WAS CLIMBING THRU ABOUT 800 FT AGL, WHEN THE PLT NOTED A SEVERE SHUDDER & VIBRATION. HE LOWERED THE COLLECTIVE, THEN NOTICED THAT THE N2 & ROTOR RPM WERE PEGGED AT 110%. AS HE REAPPLIED THE COLLECTIVE TO STOP THE OVERSPEED, HE NOTED A LOSS OF THRUST & BEGAN AN AUTOROTATION. THE ONLY SUITABLE AREA OF LAND WAS ON A MUD FLOWN. THE PLT WAS UNABLE TO TURN INTO THE WIND IN THE LANDING AREA. SUBSEQUENTLY, THE HELICOPTER RECEIVED EXTENSIVE DAMAGE DURING AN AUTOROTATIVE LANDING, DOWNWIND, ON ROUGH TERRAIN. A DISASSEMBLY & EXAM OF THE ENG REVEALED THAT THE SHAFT BEARING (#21), PN 1-300-082-01, AND THE N2 TACHOMETER DRIVE SPUR GEAR, PN 1-070-062-04, HAD FAILED. FATIGUE WAS FOUND ON THE SPUR GEAR.
