Aircraft Accident/Incident Report

Mcgrath, Alaska 99627
Wednesday, June 16, 2004 10:00 AKD

NTSB Narrative Summary Released at Completion of Accident

The commercial certificated pilot was landing in an open area of tundra next to a creek. As the airplane touched down, the pilot said he realized that the tundra surface was soft and wet. During the landing roll, the main landing gear tires dug into the soft terrain, and the airplane nosed over. The pilot, who is a certificated aviation mechanic, reported that the airplane received damage to the left wing lift strut, the rudder, and the vertical stabilizer.

NTSB Probable Cause Narrative

The pilot's selection of unsuitable terrain for landing, which resulted in the airplane nosing over during the landing roll. A factor contributing to the accident was the presence of soft tundra.
