The flight instructor stated that the helicopter was in cruise flight at 75 mph and 800 ft mean sea level when he announced “simulated engine failure” and reduced the throttle and collective. The student pilot responded to the simulated emergency by establishing an autorotation and cross-checking the instruments, which were all “normal” or “in the green.” During recovery of the maneuver at 100 ft above ground level, the instructor noted the engine rpm was “zero,” announced an actual engine failure, joined the student pilot on the flight controls, and completed the autorotation to the ground. At touchdown, the helicopter bounced on the right front skid and rolled onto its right side. The helicopter was recovered to the operator’s facility, where an engine start was attempted on the airframe using the helicopter’s battery and starter. The engine started immediately and ran smoothly without interruption until manually shut down.
Probable Cause: A total loss of engine power for reasons that could not be determined following a successful postaccident engine run on the accident helicopter.
