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 helicopter was damaged in a roll-over during a forced landing on a soft plowed field. The pilot stated that he was checking another company pilot and in doing so he abruptly reduced power to simulate engine failure. A total loss of power occurred. The acft was at 1800 ft MSL. An autorotation was made onto a soft plowed field. The pilot initiated a flare at 50 ft AGL with the acft skidding 20 ft and spinning around 180 degrees before coming to rest on its right side.a later version of the operators manual states that caution should be used in abrupt power changes due to the sensitivity of the fuel injected engines. The manual for this acft does not contain that statement. The pilot and operator stated during interview that the throttle was abruptly reduced.
