NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot reported that the engine started running roughly about 8 to 10 minutes into an agricultural application flight. He tried various magneto switch positions to troubleshoot the problem; however, the engine continued to lose power, so the pilot executed a forced landing in trees on flat terrain. Postaccident engine examinations revealed that the engine's propeller was locked in place due to a failure in the engine power section.

The mechanical failure of the engine power section, which resulted in a loss of engine power.
