An aerial application airplane experienced engine failure shortly after takeoff in a tailwind, forcing the pilot to land on a gravel road and ditch during an attempt to dump his load.

What happened

The aircraft departed en route to a rice field for aerial application work. The pilot reported that the airplane seemed slightly weak during the initial climb. Consequently, the pilot elected to remain in ground effect for approximately one mile while maintaining a gradual right turn at an altitude of about 30 feet above ground level.

During this maneuver, the engine experienced a sudden disruption described as popping, followed by backfiring and complete power loss. In response to the emergency, the pilot attempted to dump the agricultural load. The aircraft subsequently impacted a gravel road, struck a ditch, and slid into an adjacent cotton field.

The investigation

Following the accident, Federal Aviation Administration inspectors conducted a thorough examination of the engine. Their inspection revealed no evidence of mechanical malfunction or pre-impact failure that would explain the loss of power.

Probable cause

The pilot's decision to continue flight in ground effect with a weak engine, which resulted in an in-flight engine failure and subsequent forced landing.
