Chillhowee Glider Port Airport
Aircraft Accident/Incident Report

Benton, Tennessee 37307
Wednesday, October 30, 1996 18:00 EST

NTSB Narrative Summary Released at Completion of Accident

The glider collided with a tree during final approach to landing on runway 21. According to the instructor and the student, they did not see the tree because of dusk lighting conditions, which placed the sun low on the horizon and produced glare on the glider canopy. The instructor stated that the tree was about 300 feet from the runway threshold. Runway obstacle information indicated that the threshold for the runway was displaced 200 feet.

NTSB Probable Cause Narrative

failure of the flight crew to maintain altitude/clearance above runway obstacles, and inadequate supervision by the flight instructor. Factors relating to the accident were sunglare on the canopy, and the proximity of obstacles (trees) to the runway.
