Narrative:The pilot conducted a 20-minute flight over his farm and was on final approach to his landing pad when the engine started "missing and backfiring," and lost power at approximately 400 feet altitude. The pilot performed an autorotation to a soybean field, and as the helicopter touched down, it slid forward a few feet, then rolled over on its left side when a skid caught in the soft ground. Data downloaded from the FADEC revealed that for a 40-second period near the end of the flight, the engine temperature increased to 123 degrees centigrade, 22 degrees above the redline limit, before it stopped producing power. The FADEC was subsequently installed on a test cell engine, and the #1 and #2 ECUs were operated throughout the engine's full operational range, independently and together, without malfunction.
Probable Cause: The soft terrain condition, which resulted in the helicopter's rollover during the forced landing. A factor was the loss of engine power due to engine overtemperature for undetermined reasons.
