Narrative:
THE PILOT STATED HE LANDED ON THE GLACIER WHERE HE NORMALLY LANDED, 'IN THE SAME TRACKS.' WHILE HE WAS LEANING OUT THE DOOR TO CHECK THE POSITION OF THE SKIDS THE HELICOPTER NOSED DOWN AND THE MAIN ROTOR BLADES CONTACTED THE SURFACE OF THE ICE WHICH CAUSED THE HELICOPTER TO PIVOT 180 DEGREES ABOUT THE NOSE. EXAMINATION OF THE LANDING AREA SHOWED A DEEP CREVASSE, IN THE AREA OF THE RIGHT SKID'S LANDING POSITION, THAT WAS FILLED WITH CLEAR WATER. THE TOE OF THE RIGHT SKID HAD NO ICE TO REST ON AND FELL INTO THE CREVASSE.

Probable Cause: THE PILOT'S SELECTION OF UNSUITABLE LANDING TERRAIN. A FACTOR WAS THE CREVASSE IN THE ICE.
