An agricultural airplane lost power during a course reversal maneuver, forcing a landing in a field where it struck a dirt bank and burned.

What happened

The incident involved an agricultural airplane engaged in crop dusting operations. During the execution of a course reversal maneuver, the aircraft experienced a sudden loss of engine power. Unable to maintain altitude or airspeed, the pilot was forced to execute an emergency landing in an adjacent field.

During the forced landing sequence, the aircraft collided with a dirt bank. The impact caused significant structural damage, and the airplane came to rest approximately 100 feet from the initial point of impact. Following the collision, a post-impact fire broke out, which ultimately destroyed the aircraft.

The investigation

Following the accident, investigators examined the engine to determine the cause of the power loss. The physical inspection revealed a fracture and subsequent failure of the number three cylinder. This mechanical failure was identified as the primary reason for the loss of engine power that led to the forced landing.

Probable cause

The failure of the number three cylinder, which resulted in the loss of engine power during the course reversal maneuver.
