Probable cause

The pilot’s inadequate fuel planning, which resulted in a total loss of engine power due to fuel exhaustion. Contributing to the accident was the pilot’s distraction and subsequent failure to have the airplane refueled.

Findings · 5

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot landed after completing an aerial application to a field, and planned to refuel the airplane while the application tank was reloaded. He said that among other distractions, he was having problems with his global positioning system, and began discussing it with another pilot. The pilot reported that after takeoff, he realized that he did not have the ground crew refuel the airplane. He said that the destination field was close, so he decided to continue rather than return and refuel the airplane. He indicated that the fuel gauges indicated 1/4 capacity at takeoff and were bouncing around 1/8 capacity after he completed two passes. The engine subsequently lost power due to fuel exhaustion, and the pilot landed in a flat field, which was wet and soft. During the landing roll, the airplane nosed over, substantially damaging the vertical stabilizer and rudder. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Factual narrative

The pilot landed after completing an aerial application to a field, and planned on refueling the airplane while the application tank was reloaded. He noted that among other distractions, he was having problems with his global positioning system (GPS), and began discussing it with another pilot. The pilot reported that after takeoff, he realized that he did not have the ground crew refuel the airplane. The destination field was close, so he decided to continue rather than return and fuel the airplane.
