Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of the glider reported that while on downwind, the tow airplane maneuvered to avoid another aircraft, which resulted in a slack tow line. The tow line subsequently broke, and the glider pilot initiated a landing to a nearby runway from about 900 ft above ground level (agl). During the landing roll, the glider drifted right, and the right wing impacted a taxiway sign, which resulted in substantial damage to the wing spar. The pilot reported that there were no preaccident mechanical malfunctions or failures with the glider that would have precluded normal operation.
