Analysis

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.
