| Confidence Rating: |  Accident investigation report completed and information captured |
The helicopter was engaged in fire fighting operation (aerial observation) when the accident occurred. The pilot reported that the helicopter was in a cruise configuration 200 - 400 feet above ground level (AGL) when the engine lost power. The pilot initiated an autorotation and the helicopter descended into heavily wooded terrain. Two days after the accident, before the helicopter could be recovered, the on-going forest fire burned over the helicopter and destroyed the aircraft, engine and associated system components. Examination/teardown of the engine and associated components did not reveal any evidence of a pre-impact part failure or signs of abnormal wear.
Probable Cause: Power loss during cruise flight for undetermined reasons. Factors include mountainous terrain and trees.
