## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - in flight, takeoff - initial climb
  - glider launch/tow equipment - disconnected
  - airspeed(vs) - not maintained, pilot in command (cause)
  - inadequate training, pilot in command (contributing factor)
  - stall - not corrected, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE GLIDER WAS DESTROYED DURING GROUND CONTACT AFTER STALLING AT APRX 250 FT AGL. THE PLT REPORTED THAT CONFLICTING TRAFFIC RESULTED IN AN ACCELERATION OF THE TOW TRUCK AND A PREMATURE RELEASE OF THE TOWED ACFT. AFTER THE RELEASE THE ASCENDING ACFT STALLED AND HIT THE GROUND AFTER 2 AND 1/2 VERTICAL ROLLS. THE NOSE DOWN IMPACT WAS NEXT TO RWY 31/13.

## 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 19840819041259A](https://openairdocs.org/incident/19840819041259A), Aug 19, 1984: Scwzer SGS126E, Mineral Wells, TX, Destroyed. Truck towing glider slowed due to traffic on final. Late release of tow line and glider spun to the ground.

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.
