Accident Sequence
During an agricultural spraying operation, the pilot returned to land on an asphalt highway to reload with chemicals. As the aircraft flared for landing, the engine accelerated to approximately two-thirds throttle without any movement of the throttle control. The pilot believed the throttle was in the off position at that time. A nose-high attitude developed, prompting the pilot to advance the throttle to stabilize the aircraft. However, the engine then completely lost power. A crosswind was present, causing the aircraft to drift to the left of the roadway. The pilot subsequently attempted to land in a bean field, but the aircraft struck a fence and terrain, resulting in damage.
Post-Crash Examination
During a post-crash examination, no fuel was found in the fuel tanks, and no evidence of fuel leakage was discovered.
