## Analysis

THE ACFT WAS OBSERVED TO ENTER A LEFT BASE LEG FOR RWY 4. THE PLT CONTINUED TO FLY THE BASE LEG HEADING & FLEW THRU THE FINAL APCH LEG. THE ACFT THEN ENTERED A RIGHT BANK, & AFTER 180 DEG OF TURN, IT STALLED & WENT INTO A RIGHT SPIN AT AN ESTIMATED 600 TO 800 FEET. NO VISIBLE ATTEMPTS TO RECOVERED WERE NOTED. THE GLIDER CRASHED IN A FIELD ALONG THE FINAL APCH COURSE TO RWY 4. NO PREIMPACT STRUCTURAL FAILURE OR FLT CONTROL MALFUNCTION WAS FOUND.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19840609023199A](https://openairdocs.org/incident/19840609023199A), Jun 9, 1984: Scwzer SGS126E, Williston, FL, Substantial damage. Overshot runway alignment turning final. Stalled in a steep turn trying to correct flight path and entered spin.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
