During landing, a glider collided with a tree after the pilot misjudged clearance, tearing off the right wing. The glider spun 270 degrees. No mechanical malfunctions were reported.

Accident Details

During the landing approach, the glider successfully cleared a set of power lines and continued descending. At an altitude of 15 feet above ground level (AGL), the pilot observed a tree ahead. The glider deviated to the right side of the runway centerline. The pilot attempted to judge the distance from the tree to the wing, but misjudged the clearance. Consequently, the wing contacted the tree, causing it to be torn from the fuselage. The glider then rotated 270 degrees from its flight path before coming to rest.

Pilot's Report

The pilot stated that no mechanical malfunctions were noted with the glider prior to the accident. As a preventive measure, the pilot recommended flying a higher approach to avoid similar incidents in the future.

Probable cause

The pilot misjudged the clearance between the tree and the wing.
