Probable cause

A partial loss of engine power during the takeoff roll for undetermined reasons.

NTSB narrative

The pilot performed an uneventful preflight inspection and engine run-up prior to departing for the aerial application flight. During the takeoff roll, about 2/3 of the way down the runway, the engine lost partial power. The pilot attempted to force the airplane airborne with control inputs; however, it struck a gate at the end of the runway and nosed over. A subsequent examination of the engine and airframe did not reveal any anomalies that would have precluded normal operation.

Analysis

Primary failure mode
Engine power loss
