## Sequence of events

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

- Abrupt maneuver, takeoff - initial climb
  - glider launch/tow equipment - disconnected (contributing factor)
  - maneuver - excessive, pilot in command (cause)
  - altitude - inadequate, pilot in command (cause)
- Loss of control - in flight, takeoff - initial climb
  - stall/spin - not corrected, pilot in command (cause)
  - lack of total experience in type of aircraft, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE GLIDER MADE A STEEP NOSE HIGH TURN, STALLED AND CRASHED AFTER A PREMATURE TOW RELEASE AT APRX 150 FT AGL. WITNESSES SAID THAT THE GLIDER APPEARED TO BE BADLY CONTROLLED FROM THE BEGINNING OF THE TAKEOFF ROLL. AFTER THE STALL DURING THE TURN THE ACFT ENTERED A SPIN PRIOR TO GROUND IMPACT.
