Probable cause

The pilot’s improper preflight inspection and fuel planning, which resulted in a total loss of engine power due to fuel exhaustion.

NTSB narrative

Just after takeoff on the agricultural application flight, the commercial pilot was positioning the airplane to spray a rice field. About 200 ft above ground level, the pilot heard a loud pop, and the engine experienced a total loss of power. The pilot turned the airplane to land on a dirt road, but it was too narrow; the right main landing gear contacted mud on the side of the road, and the airplane subsequently nosed over and came to rest inverted. Recovery personnel reported no residual fuel on the ground around the accident site, and about one half gallon of fuel was recovered from the airplane. The pilot stated that the airplane had not been refueled on the day of the accident and that he departed on the flight with less than a half tank of fuel. The postaccident engine examination revealed no mechanical anomalies that would have precluded normal operation. The loss of engine power was likely due to fuel exhaustion, and given that the loss of power occurred just after takeoff, it is likely that the pilot did not verify the amount of fuel onboard before departing on the flight.
