Probable cause

The pilot's inadequate in-flight planning/decision making and subsequent loss of engine power due to fuel exhaustion. Contributing factors were the terrain conditions (soft and rough/uneven) and the tailwind weather conditions.

Sequence of events

Analysis

The pilot said that he departed at approximately 0820 to apply mosquito larvicide to local wetlands. Upon completion of his application runs, he started a climb towards the airport and experienced a loss of engine power. He selected a spot for a forced landing, which proved to be pasture with heavy marsh grass, and too soft and rough for a downwind landing. During rollout, the right main landing gear collapsed, and the airplane ground looped to the right. Postaccident evaluation of the airplane revealed that the right main landing gear failed, a rib was bent in the right wing, and both wing tips were damaged. The pilot reported that the cause of the engine failure was fuel exhaustion.
