## Probable cause

THE FAILURE OF THE PILOT TO MAINTAIN ADEQUATE AIRSPEED TO AVOID STALLING THE AIRCRAFT.

## Sequence of events

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

- Loss of control - in flight, approach - vfr pattern - base leg/base to final
  - airspeed(vs) - not maintained, pilot in command (cause)
  - stall - uncontrolled, pilot in command (cause)
- In flight collision with object, descent - uncontrolled
  - object - tree(s)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - ground

## Analysis

THE CERTIFICATED PRIVATE GLIDER PILOT WAS RETURNING TO LAND AT HIS DEPARTURE AIRPORT AND WAS OBSERVED ON A LEFT BASE APPROACH ABOUT 100 TO 200 FEET ABOVE THE GROUND. THE GLIDER WAS FLYING SLOWLY AND AS A LEFT TURN WAS INITIATED TO A FINAL APPROACH HEADING, THE AIRCRAFT WAS OBSERVED TO SHUDDER AND STALL. THE GLIDER THEN DESCENDED VERTICALLY INTO A PEACH ORCHARD STRIKING TREES AND THE GROUND. THE PILOT WAS FATALLY INJURED AND THE GLIDER DESTROYED.
