While maneuvering after completing a spray pass, the pilot heard a "loud pop," and the agricultural airplane's engine lost power. The pilot executed a forced landing to a clearing in a field.

The operator stated that an examination of the engine revealed that #9 cylinder had cracked, and subsequently, a connecting rod failed.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

a loss of engine power due to a crack in the #9 cylinder, which result in the failure of the connecting rod during the aerial application flight. A contributing factor was the lack of suitable terrain for the forced landing.
