NTSB Narrative Summary Released at Completion of Accident

THE PILOT AND THREE PASSENGERS WERE FLYING AT LOW ALTITUDE OVER MOUNTAINOUS TERRAIN LOOKING FOR BIG HORN SHEEP. THIRTY MINUTES INTO THE FLIGHT THE PILOT HEARD A LOUD NOISE AND THE TAIL YAWED LEFT. THE PILOT TURNED AWAY FROM THE MOUNTAIN TO LOOK FOR A PLACE TO LAND. THE ENGINE LOST ALL POWER. BECAUSE IT WAS NECESSARY TO STRETCH THE GLIDE TO REACH THE ONLY AVAILABLE LANDING SPACE, THERE WAS INSUFFICIENT ROTOR SPEED REMAINING TO CUSHION THE LANDING. THE AIRCRAFT LANDED HARD, BREAKING THE RIGHT LANDING SKID AND ROLLING OVER ONTO ITS SIDE. EXAM OF THE ENG REVEALED THAT THE NO. 6 & 7 BEARINGS WERE FOUND TO HAVE FAILED DUE TO OIL STARVATION. THE REASON FOR THE OIL STARVATION COULD NOT BE DETERMINED.
