Probable cause
A cracked engine cylinder assembly, which resulted in loss of engine power.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot stated that after about 20 minutes of aerial application, the airplane engine 'began sputtering and backfiring....the engine quit.' The pilot made a left turn to avoid obstacles, and landed. During the landing roll, the airplane's left wing contacted the edge of a mature corn field, and the airplane spun approximately 120 degrees before it came to a stop. Examination of the radial engine revealed a crack in the number 1 cylinder which extended from the right side of the front spark plug to the back side of the cylinder intake port; the air filter was blown through the induction intake. There was no other evidence of mechanical malfunction.
