Aircraft Accident/Incident Report

Tullahoma, Tennessee 37360
Friday, April 12, 2013 12:30 CDT

NTSB Narrative Summary Released at Completion of Accident

According to the pilot, he was on a one mile final approach to runway 36 at 800 feet with the glider engine stowed. He noted that the wind was changing and extended the flaps. The airspeed was between 55 and 60 knots when the airbrakes were extended to start a descent. The altitude was high and the glider began to descend at a rapid rate. The pilot closed the airbrakes to arrest the descent rate but realized he was to low and unable to land on the intended runway. The glider collided with a tree, and a post-accident examination revealed that the left wing was substantially damaged. The pilot reported no pre-impact mechanical malfunctions or failures with the airplane that would have precluded normal operation.

NTSB Probable Cause Narrative

The pilot's improper use of wing spoilers during approach resulting in an altitude loss and collision with a tree.
