Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The plt stated the helicopter lost pwr during cruise when he attempted to add pwr to climb. He stated that N2 decreased along with the activation of visual and audio engine out warnings. An autorotation was performed to a road, however, the helicopter slid off the road and down a 50 deg slope in the terrain before coming to rest. Post accident tests revealed the fuel governor, p/n 104100A12-A8, had an excessive leakage rate at the bypass valvue and the deceleration and slope tests were out of limits. When retested, the governor was found capable of normal operation.
