NTSB narrative
THERE WAS CONFUSION BETWEEN THE TOW PILOT AND THE GLIDER PILOTS ON THE PLAN OF WHO WAS GOING TO BE TOWED BY WHAT TOW PLANE. ONE GLIDER PILOT BEGAN RETRIEVING THE TOW ROPE USING AROUND-THE-WAIST FASHION VERSUS USING A TOW ROPE HOOK. THERE WAS CONFUSION ON THE HAND SIGNAL TO STOP THE AIRPLANE BETWEEN THE TOW PILOT AND GLIDER PILOT, AND INSTEAD THE TOW PLANE INCREASED TAXI SPEED TO ABOUT 15 MPH. THE GLIDER PILOT BECAME ENTANGLED IN THE TOW ROPE AND WAS KNOCKED TO THE GROUND. THE SORING ASSOCIATION DID NOT HAVE A DISPATCHER PRESENT AT THE TIME OF THE ACCIDENT.
Probable cause
a communication misunderstanding between the tow pilot and the glider pilot. Factors related to the accident were: the tow rope becoming entangled, excessive taxispeed by the tow pilot, and the unavailability of a dispatcher.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, damage. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
- API snapshot SHA-256: 2e6fc6df7a5062d07c89f4f0e7ff23b5c002be8fa9bdcc646a261b302f9f511a; retrieved 2026-09-21T13:03:52.651Z.
