Aircraft Accident/Incident Report

Granite, Colorado 81228
Saturday, July 9, 1994 19:48 MDT

NTSB Narrative Summary Released at Completion of Accident

THE AIR AMBULANCE (EMS) HELICOPTER WAS DISPATCHED TO PICK UP AN INJURED HIKER ON A 14,000' MOUNTAIN. TERRAIN AT THE PICKUP POINT WAS AT AN ELEVATION OF ABOUT 12,200' AND SLOPED APPROXIMATELY 35 DEGREES. GROUND RESCUE PERSONNEL SAID THE PILOT ADVISED THEM HE WOULD PLACE THE HELICOPTER'S RIGHT SKID ON THE MOUNTAIN SLOPE TO ALLOW THEM TO LOAD THE PATIENT ON THE DOWNHILL SIDE. AS THE HELICOPTER HOVERED ABOVE THEM, THE MAIN ROTOR BLADES STRUCK ROCKS. THE HELICOPTER THEN WENT OVER THEIR HEADS, CRASHED, AND SUBSEQUENTLY TUMBLED ABOUT 800' DOWN THE MOUNTAIN.

NTSB Probable Cause Narrative

FAILURE OF THE PILOT TO ASSURE MAIN ROTOR CLEARANCE FROM SLOPING TERRAIN WHILE IN A HOVER. THE TERRAIN CONDITION WAS A RELATED FACTOR.
