Probable cause & findings

The dual student's misjudged distance/altitude during the final approach to land, and the flight instructor's inadequate supervision of the student, which resulted in an undershoot, and substantial damage.

Factual narrative

On June 9, 2007, about 1004 Alaska daylight time, a Schleicher ASK-21 glider, N621CP, sustained substantial damage when it landed short of the runway at the Clear Airport, Clear, Alaska. The airplane was being operated by Civil Air Patrol Inc, Fairbanks, Alaska, as a visual flight rules (VFR) instructional flight under Title 14, CFR Part 91, when the accident occurred. The flight instructor and student pilot were not injured. Visual meteorological conditions prevailed, and no flight plan was filed. In a written statement to the National Transportation Safety Board (NTSB) dated July 13, the instructor wrote that he was providing instruction to the student pilot, and that on short final the student deployed full spoilers causing the glider to touch down short of the runway threshold. He wrote that the nose wheel impacted the leading edge of the runway, which damaged the nose wheel mount and fiberglass fuselage. According to the pilot, there were no known mechanical anomalies with the glider prior to the accident. The flight instructor was conducting student training in the airport traffic pattern under Title 14, CFR Part 91. On short final the dual student deployed full spoilers, resulting in the glider touching down short of the runway. The nose wheel of the glider impacted the edge of the runway threshold, damaging the landing gear attachment and the fuselage.
