Incident Overview
An agricultural spray airplane was destroyed when it impacted terrain and was subsequently consumed by post-impact fire during a forced landing. The event occurred after the aircraft experienced a loss of power during takeoff from an asphalt runway.
Pilot Account
The pilot reported that he had completed the sixth spray load of the day and landed to refuel and load chemicals. He topped off the fuel tanks and added approximately 115 gallons of pesticide water mix. The airplane was functioning normally at departure. However, at about 100 feet above ground level (agl) near the departure end of the runway, the engine began to lose power. The pilot determined that he did not have sufficient power or altitude to execute a 180-degree turn back to the airport, nor could he reach a road for an emergency landing. He dumped the load and landed in a corn field west of the airport. After the airplane came to rest, it caught fire and was completely consumed. The pilot exited the aircraft and received minor injuries.
Witness Observation
A witness reported observing the airplane during takeoff and heard the engine sputtering and backfiring as the aircraft banked to the west.
Inspection Findings
Inspection of the airplane revealed damage to the engine and its accessories. However, the extent of impact and post-impact fire damage precluded the identification of any mechanical anomalies that may have been present prior to the accident.
