## Probable cause

UNEXPECTED ENCOUNTER WITH ADVERSE WIND (DOWNDRAFT).

## Sequence of events

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

- In flight encounter with weather, takeoff - initial climb
  - weather condition - downdraft (cause)
- Forced landing, descent - emergency
  - terrain condition - none suitable
  - terrain condition - rough/uneven
- In flight collision with terrain/water, descent - emergency
  - terrain condition - rising

## Analysis

ACCORDING TO THE PILOT, DURING HIS TAKEOFF CLIMB, HE ENCOUNTERED A DOWNDRAFT AND WAS UNABLE TO PREVENT HIS AIRSPEED FROM DROPPING DANGEROUSLY LOW AS HE TRIED TO MAINTAIN FLIGHT.  HE SAID HE WAS FORCED TO MAKE A FORCED LANDING BEFORE THE AIRCRAFT STALLED.  THE AIRCRAFT STRUCK THE GROUND IN A RELATIVELY FLAT ATTITUDE AND THEN STRUCK SOME RISING TERRAIN.
