Analysis

The acft came to rest inverted with the engine under water after a power loss and forced landing. The plt stated that he started losing power in the turn to line up for his first aerial application run. The acft settled to ground impact in a landing attitude despite full throttle and jettison of load. The left landing gear broke off on an embankment and the acft nosed over into a water filled ditch. Since the engine was submerged for several days no engine teardown was accomplished. No malfunctions were found during the on-site investigation. There were no witnesses to the accident.
