The NTSB's narrative final · quoted from the NTSB record

DURING A CROSS COUNTRY FLIGHT THE AIRCRAFT EXPERIENCED LOSS OF ENGINE POWER. THE LANDING RESULTED IN THE CATASTROPHIC COLLAPSE OF THE LANDING GEAR. THE HELICOPTER WAS NOT OF A STANDARD CONFIGURATION, IT WAS RIGGED WITH EARLY TECHNOLOGY RIDIG FLOATS. THESE FLOATS DRASTICALLY CHANGE THE FLIGHT ENVELOPE OF THE HELICOPTER ESPECIALLY DURING EMERGENCY PROCEDURES SUCH AS AUTOROTATIONS.
