NTSB narrative
THE PLT WAS QUALIFIED FOR SOLO WINCH LAUNCHES IN AN SGS-1-26 GLIDER. ON HIS 1ST WINCH LAUNCH USING A C.G. HOOK IN THIS GLIDER, HE ALLOWED THE ACFT TO ENTER AN ABNORMALLY HIGH ANGLE OF ATTACK, WHICH WAS OBSERVED THRU-OUT THE TAKEOFF PROCESS. THE GLIDE THEN ENTERED A STALL-SPIN & CRASHED. ACCORDING TO THE OWNER'S MANUAL, FORWARD ELEVATOR MUST BE USED AFTER LEAVING THE GROUND DUE TO THE LOCATION OF THE TOW HOOK & THE TENDENCY OF THE GLIDER TO ENTER A STEEP NOSE-UP ATTITUDE. THE MANUAL REQUIRED PRONOUNCED FORWARD PRESSURE THRU-OUT THE TRANSITION ARC.

- 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. 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.
