## Sequence of events

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

- In flight collision with object, takeoff - initial climb
  - planning/decision - improper, pilot in command (cause)
  - weather condition - gusts (contributing factor)
  - object - tree(s) (contributing factor)
  - proper climb rate - not maintained, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PILOT USED FULL POWER AND 10 DEGREES OF FLAPS TO PERFORM A SHORT FIELD TAKEOFF FROM A SOD STRIP. HE ROTATED FOR TAKEOFF LESS THAN HALFWAY DOWN THE 1100 FT RUNWAY, THEN KEPT THE ACFT LOW TO ACCELERATE TO 80 KTS. HE THEN PULLED UP TO CLEAR A ROW OF 40 FT TREES. FOLLOWING THIS, HE LOWERED THE AIRCRAFT'S NOSE TO BUILD UP MORE AIRSPEED. DURING THIS MANEUVER, HIS LEFT WING HIT THE TOP OF A TREE IN A SECOND ROW OF TREES AND THE AIRCRAFT THEN FELL TO THE GROUND. THE PILOT REPORTED THAT THE WINDS WERE FROM THE WEST AT 15 GUSTING 20 KTS.
