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 plt reported that he was spraying a field that was bordered by obstacles. When he was about half way thru a procedure turn, the eng began 'backfiring & losing power.' The plt moved the throttle to about the 1/2 power setting, hoping the condition would be corrected, but to no avail. There was a high power line on one side of the field & a 300 ft transmitting tower on the other. Also, there was a wooded area at the end of the field. Therefore, the plt elected to make an emergency landing in a small, rolling field. During the landing, the gear collapsed & the wings were damaged. An exam of the eng revealed that the front spark plugs were sooty; the rear spark plugs were rusted & could not be removed; the #2, #4 & #8 cylinders had blown exhaust gaskets; the left magneto timing bushing was worn excessively & the magneto was found to be loose.
