| Confidence Rating: |  Accident investigation report completed and information captured |
As the helicopter approached the airport, the pilot reported that the helicopter's engine rpm increased, and the rotor rpm decayed. He conducted an autorotation to the field. An examination of the helicopter revealed that the helicopter's main rotor drive belt/cog belt lost teeth resulting in a failure of the belt to drive the main rotor blades. The drive belt had recently been installed, about 3.5 hours prior to the accident. The circumstances of the accident are consistent with improper tension of the cog belt resulting in a failure of the belt.
Probable Cause: A failure of the drive belt for reasons that could not be determined based on the available information.
