Incident Overview
During an agricultural swath run, an aircraft was approximately one-third of the way through its procedure turn when the engine suddenly lost power. The pilot extended the glide to clear nearby powerlines, but upon flaring to land, the airspeed was insufficient to arrest the descent. The aircraft impacted the ground hard, causing the main landing gear to collapse and the aircraft to nose over.
Investigation Findings
Post-incident examination of the engine revealed malfunction damage to the engine drive train gears. The damage was severe enough to result in a total loss of engine power. Additionally, the aircraft was operating on autogas (automotive gasoline) without a Supplemental Type Certificate (STC) approval.
Operational Details
The flight was conducted as part of agricultural spraying operations. The specific aircraft type, registration, operator, and location were not documented in the available source. No information was provided regarding occupants, injuries, time of day, weather conditions, or air traffic control involvement.
