Aircraft Accident/Incident Report

Delta Junction, Alaska 99737
Monday, May 23, 2005 10:00 AKD

NTSB Narrative Summary Released at Completion of Accident

The commercial certificated pilot was transporting hunting and camp supplies to a remote area in support of a hunting party. He landed the tundra tire-equipped airplane on a remote mountain ridge where previous wheel tracks were visible. During the landing roll, the pilot said that when he applied the brakes, the large tundra tires began to bounce over the rough terrain, and he was being careful not to apply excessive braking action. The airplane overran the pilot's intended landing area, and the right main tire encountered a depression. The right wing and propeller struck the ground. The aircraft mechanic who repaired the airplane reported that he repaired the leading edge of the right wing, and replaced a wing nose rib.

NTSB Probable Cause Narrative

The pilot's selection of unsuitable terrain for landing, which resulted in an overrun. A factor contributing to the accident was rough and uneven terrain.
