BELL 47J-2A
WHILE ON A SIGHT-SEEING FLT OVER A PARK, THE PLT HEARD A LOUD NOISE & THE HELICOPTER SHUDDERED & LOST POWER. AT THAT TIME, THE ACFT WAS OVER A CANYON, SO THE PLT LOOKED FOR THE FLATEST AREA TO LAND & BEGAN AN AUTOROTATION. DURING THE LANDING, THE HELICOPTER BOUNCED INSTEAD OF SLIDDING. SUBSEQUENTLY, THE SKIDS BENT, THE TAIL ROTOR HIT THE GROUND & THE MAIN ROTOR BLADES HIT THE TAIL BOOM. AN INVESTIGATION REVEALED THAT THE ENG FAILED AFTER A CONNECTING ROD BOLT HAD FAILED.
