An airplane bounced during landing on a grass strip. The pilot attempted to stop but lacked sufficient runway distance, resulting in an overrun through a fence.

What happened

During the final phase of flight, the aircraft was attempting to land on a grass surface strip. Upon touchdown, the airplane experienced a bounce off the ground. In response to this event, the pilot applied engine power to arrest the descent and allow the aircraft to settle back onto the runway surface.

After settling, the pilot assessed the remaining distance available for deceleration. The pilot determined that the 1,500-foot length of the strip was adequate to bring the airplane to a complete stop. Consequently, braking procedures were initiated.

Despite the application of brakes, the aircraft failed to achieve a safe stopping distance within the confines of the runway. The airplane continued its forward momentum beyond the paved or prepared edge of the grass strip. It crossed through a barbed wire fence located at the end of the available runway area and came to rest in an adjacent open field.

Probable cause

The pilot's failure to ensure sufficient runway remained available to stop after a bounced landing, resulting in an overrun.
