Manila, AR, US

On September 19, 1993, a Cessna A188B (registration N731UF) was involved in an aviation accident near Manila, AR.

The airplane failed to accelerate due to engine power loss. After dumping the load, it lifted off near the runway end but could not accelerate, settling into a cotton field. The spray boom snagged cotton, causing a left pull and ground impact.

Accident Sequence

The airplane experienced a loss of engine power, preventing it from accelerating properly. The pilot jettisoned the load, after which the aircraft became airborne approximately 100 feet before the end of the runway. However, it still did not gain sufficient speed and subsequently settled into a cotton field roughly 300 feet beyond the runway end. During the descent, the spray boom caught the cotton crop, causing the airplane to yaw to the left and impact the ground.

Examination Findings

Post-accident inspection of the double wall air induction hose revealed that the inner wall had separated. This separation blocked the air intake, leading to the loss of engine power.

Probable Cause

The probable cause of the accident was the loss of engine power due to a blocked air intake, caused by separation of the inner wall of the double wall air induction hose.
