CASPER, WY, USA
N2762G
Bell 206B-3
The pilot stated that the helicopter's engine flamed out, and he made an autorotation to a county road. During a slide-on landing, the right skid gear broke, and the helicopter rolled over on its right side. The pilot noted that he did not recall an audio warning, and the rpm had bled down before landing. He stated that he had made two earlier precautionary landings during the flight, due to the flight being conducted in visible precipitation. In both instances, he stated that he found no evidence of ice or snow buildup in the intake system. The engine was later removed and tested in a test cell, where it functioned normally. Sufficient fuel was found on board the helicopter. FAA inspectors noted that the loss of power occurred at an airspeed and altitude that may have precluded a successful forced landing.
