The NTSB's narrative final · quoted from the NTSB record
The pilot was dispensing fertilizer from a cropduster. Just before beginning a course reversal at the end of his second swath run, the Curtiss-Wright R-1820 (1200 horsepower) radial engine 'experienced a sudden and near complete loss of power' for undetermined reasons. The pilot reported that, just before starting the course reversal, he perceived a loss of engine power through a degradation of engine noise and airspeed, but the engine did not completely quit. He dumped the 2,400 pound load, maneuvered to avoid a residence and executed a forced landing to rough terrain. During the landing roll, the right landing gear collapsed. The pilot reported that this was the second flight of the morning at the same load weight. An examination of the engine revealed no mechanical malfunction.
