Pilot's Report
The pilot reported that while conducting passes over a field, he observed that his airspeed had decreased to 80 miles per hour. At that moment, the engine was set to a normal power configuration with manifold pressure at 32 inches and engine speed at 2,500 rpm. In an effort to increase airspeed, the pilot leveled the aircraft's wings and lowered the nose. When the airspeed did not respond, he advanced the throttle to the full power position. Despite this action, the airspeed continued to decay, and the aircraft began to descend. The pilot then attempted to jettison the 125 gallons of chemical on board, but the jettison system did not operate successfully. The aircraft subsequently mushed into the field.
Damage Assessment
An examination of the aircraft following the incident revealed several structural damages. The propeller had separated from the engine and exhibited signs of torsional failure. The left wing was bent in a rearward direction. The left main landing gear was broken and displaced aft from its normal position. Additionally, a thorough inspection of the aircraft's systems, including the engine, flight controls, and avionics, found no anomalies or malfunctions.
