  - stall/spin - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PLT WAS ATTEMPTING TO ACHIEVE A CLUB DURATION/ALTITUDE GAIN GOAL AND RELEASED FROM THE TOW PLANE AT 1,000 FT AS OPPOSED TO THE REQUESTED 3,000 FT TOW. THE PLT COMMUNICATED WITH ANOTHER GLIDER PLT IN THE AREA AND STATED HE WAS GETTING LOW AND HAD TO LAND. A GROUND WITNESS OBSERVED THE GLIDER ON A LOW AND SLOW FINAL APPROACH. THE WITNESS REPORTED THAT THE GLIDER BANKED RIGHT AND TURNED 270 DEGREES BEFORE IT SUDDENLY PITCHED NOSE DOWN FROM APRX 150 FT AGL AND IMPACTED THE GROUND. SEVEN MONTHS PRIOR TO THE ACCIDENT, THE PLT FAILED A PRIVATE GLIDER PLT CHECKRIDE DUE TO HIS LANDING APPROACH PROCEDURES.

## 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 19860617025349A](https://openairdocs.org/incident/19860617025349A), Jun 17, 1986: Scwzer SGS136, Waynesville, OH, Destroyed. The glider stalled on final and hit the ground. The pilot was noted for erratic and unsafe behavior.

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.
