## 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
  - weather condition - downdraft (contributing factor)
  - airspeed - not maintained, pilot in command (cause)
  - stall/mush - inadvertent, pilot in command (cause)
- In flight collision with object, takeoff - initial climb
  - object - tree(s) (contributing factor)
- In flight collision with terrain/water, takeoff - initial climb

## Analysis

THE ACFT CONTACTED A ROW OF TREES AND CRASHED IN A RESIDENTIAL AREA SHORTLY AFTER TAKEOFF. THE PILOT REPORTED, THAT A DOWNDRAFT WAS ENCOUNTERED AFTER ESTABLISHING A POSITIVE RATE OF CLIMB ON TAKEOFF. AIRSPEED DECREASED WHEN THE DOWNDRAFT WAS ENCOUNTERED AND THE PILOT CONTINUED FLYING THE ACFT JUST ABOVE STALL SPEED. THE AIRCRAFT CLEARED AN INITIAL GROUP OF TREES AFTER WHICH IT CONTACTED THE TOPS OF TWO PINE TREES WHICH WERE APRX 78 FT TALL. THE ACFT THEN STALLED AND DESCENDED TO IMPACT WITH THE TERRAIN.
