Accident Overview
According to the pilot, the engine shut down during the takeoff climb at an estimated altitude of 100 to 150 feet above ground level. The pilot responded by leveling the wings and pushing the nose over, then attempted a forced landing in a turf field. The aircraft struck the ground, sustaining substantial damage. The pilot exited the airplane with assistance from witnesses on the ground.
Post-Accident Examination
An FAA inspector examined the aircraft and found that the landing gear, spray equipment, and the right wing had separated from the airframe. Fuel was observed in both fuel tanks. Examination of the engine revealed that the propeller had separated from the engine crankshaft. The engine was seized due to impact damage and had rotated 90 degrees within its engine mounts. Both magnetos and the fuel manifold showed impact damage. Oil was present on the dipstick when it was removed.
Witness Observations
Witnesses on the ground reported that the engine did not run smoothly from the time of taxi through the takeoff and subsequent engine shutdown.
Regulatory Note
The FAA inspector further stated that the aircraft operator did not hold an FAA 14 CFR Part 137 Aerial Application Certificate at the time of the accident, as required by regulation.
