Primary finding
Probable cause
The pilot’s inadvertent encounter with soft terrain conditions during the landing which resulted in a loss of directional and a subsequent nose-over.
Investigator assessment
Analysis narrative
The pilot stated that during the landing on a dry grass airstrip, the airplane encountered a soft terrain area on the runway. The airplane was then pulled into a softer area toward the edge of the runway where it nosed over. The airplane sustained substantial damage to the left wing leading edge and ribs and the vertical stabilizer. The pilot reported there were no preimpact mechanical malfunctions or failures with the airframe or the engine that would have precluded normal operation. The pilot further reported that the accident could have been prevented by refraining from operating on airstrips with soft runways.
