American Champion Aircraft 8GCBC N131PM accident near Ashton, Idaho

Probable cause

The student pilot’s poor decision-making when he decided to land on a snowy grass airstrip, which resulted in an encounter with deep snow during the landing roll and a subsequent nose-over.

NTSB analysis

The student pilot reported that he approached the privately-owned, rough grass airstrip and observed that it was covered with snow. After evaluating the snow’s depth as being only a few inches, the pilot landed. During the landing roll, the airplane decelerated quickly and nosed over, bending the vertical stabilizer, wings, and lift struts. After exiting the airplane, the pilot realized that the snow was between 6- and 8-inches deep. The student pilot’s certified flight instructor reported that he had not endorsed the student’s flight record logbook in over 90 days, and he had not authorized the student to fly to the accident airport. The student was not current in the airplane.
