The pilot reported that he made two aerial application passes over the wheat field. During the reversal turn on the second pass, the airplane cleared a set of power lines and began to settle. The pilot applied full throttle, but the engine did not respond. He flared the airplane and completed a forced landing to the wheat field. During the landing, the landing gear failed, which resulted in substantial damage to the right wing. The examination of the two propeller blades revealed that they both exhibited leading edge gouges, chordwise scratches, and blade twisting, which is consistent with the engine operating at the time of ground impact. The atmospheric conditions at the time of the accident were conducive to the accumulation of carburetor ice while operating at a sustained idle engine power setting. However, the engine power setting used during the aerial application flight would have been significantly higher than an idle engine setting; therefore, it is unlikely that carburetor ice accumulated during the accident flight.
Probable Cause: The partial loss of engine power for reasons that could not be determined during postaccident examinations.
