What happened
The pilot performed a runup before initiating a takeoff roll toward the south. During the takeoff run, the pilot observed that the aircraft was not reaching an adequate speed, despite power indications appearing normal. The pilot reported that the airplane initially appeared to be operating normally but then experienced a loss of partial power.
As a result, the aircraft failed to become airborne and subsequently impacted a ditch located at the end of the runway. The aircraft was carrying a payload consisting of 165 gallons of agricultural chemicals at the time of the accident. The impact resulted in substantial damage to the wings and the landing gear.
Findings
A Federal Aviation Administration inspector noted that the pilot had not dumped the chemical payload prior to the takeoff attempt. There was no evidence reported of a mechanical malfunction occurring prior to the impact.
