Smiley Creek Airport
Aircraft Accident/Incident Report

Galena, Idaho 83340
Saturday, April 10, 2010 12:00 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that he intended to fly his airplane on a cross-country flight over high mountainous terrain. After takeoff, the pilot climbed to 9,500 feet mean sea level (msl) in order to fly over mountains. He subsequently descended to 8,500 feet msl, and then he attempted to climb back to 9,500 feet to clear additional mountains. This second climbing effort diminished his fuel reserve, so the pilot opted to divert to a 7,160-foot msl uncontrolled airport short of his destination. While flying over the airport to evaluate its runway's condition, the pilot noted that the runway was covered with snow. The pilot opined that because of the airplane's low fuel state, it was prudent for him to land. The pilot made a soft-field landing on the runway. During rollout, the airplane's wheels penetrated the snow-covered surface, the airplane nosed over, and both wings and the empennage broke.

NTSB Probable Cause Narrative

The pilot's encounter with soft, snow-covered terrain while executing a precautionary landing.
