## Probable cause

IMPROPER COMPENSATION FOR WIND CONDITIONS.

## Sequence of events

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

- In flight encounter with weather, descent - normal
  - weather condition - unfavorable wind
- Forced landing, descent - emergency
- On ground/water collision with object, landing - roll
  - object - other
  - compensation for wind conditions - improper, pilot in command (cause)
  - lack of familiarity with aircraft, pilot in command (contributing factor)

## Analysis

THE NONCERTIFICATED SOLO STUDENT PILOT DEPARTED HEMET AIRPORT ON A LOCAL SOARING FLIGHT. WHEN RETURNING THE PILOT ENCOUNTERED HEADWINDS AND FAILED TO COMPENSATE FOR THE WIND CONDITIONS. REALIZING THAT THE GLIDER'S ALTITUDE WAS INSUFFICIENT TO NEGOTIATE THE AIRPORT THE STUDENT PILOT ELECTED TO LAND IN AN OPEN FIELD. THE TOUCHDOWN WAS SUCCESSFUL HOWEVER DURING THE LANDING ROLL THE RIGHT WING COLLIDED WITH A ROCK.

## Other investigations on N1163S (1)

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.

Probable cause: the pilot's failure to maintain an adequate airspeed while maneuvering in the traffic pattern, which resulted in an inadvertent stall/spin. A factor in the accident was the pilot's low total flight…
