The NTSB's narrative final · quoted from the NTSB record

The pilot reported that, while the airplane was towing a banner about 1,100 ft mean sea level, the engine lost power. The pilot's attempts to restart the engine were unsuccessful. The pilot executed a forced landing to a pasture, during which the right wing struck a fence. The airplane then came to rest upright. The pilot reported that there were no anomalies or indications before the loss of engine power. Disassembly of the engine revealed that a crankshaft idler gear shaft had failed and separated from the accessory gear case. The failed idler gear shaft and its attachment hardware were not located, and a metallurgical examination could not be conducted to determine the reason for the failure.
