Investigators recorded the probable cause as: The pilot's inability to locate sufficient lift (thermals) leading to a forced off-airport landing, during which the right wing tip struck a road sign causing a ground loop. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A glider pilot unable to find lift landed on a dirt road, where the wing tip hit a sign and caused a ground loop.
What happened
During a cross-country flight, the pilot encountered difficulties in maintaining altitude due to an inability to locate suitable thermals. With no viable options to remain airborne, the pilot made the decision to execute an off-airport landing on a nearby dirt road. As the glider touched down and began its landing roll, the right wing tip struck a road sign positioned along the edge of the roadway. The impact caused the aircraft to lose directional control, resulting in a ground loop.
The investigation
Following the incident, the pilot reported that there were no mechanical malfunctions with the glider prior to the accident. This indicates that the aircraft was airworthy and functioning correctly up until the moment of the forced landing.
Probable cause
The pilot's inability to locate sufficient lift (thermals) leading to a forced off-airport landing, during which the right wing tip struck a road sign causing a ground loop.
