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

- In flight collision with object, approach - vfr pattern - final approach
  - object - tree(s) (contributing factor)
  - performance data - not understood, pilot in command (cause)
  - lack of familiarity with aircraft, pilot in command (cause)
  - maneuver - not understood, pilot in command (cause)
  - remedial action - improper, pilot in command (cause)

## Analysis

THE ULTRALIGHT COLLIDED WITH A TREE WHILE ON FINAL APPROACH TO LAND IN AN OPEN AREA. THIS WAS THE PILOT'S FIRST FLT IN AN ULTRALIGHT ACFT. HE SAID THAT THE ACCIDENT HAPPENED WHEN HE MADE AN IMPROPER WEIGHT SHIFT IN AN EFFORT TO AVOID A COLLISION WITH THE TREE. THE PILOT BROKE HIS LEG IN THE COLLISION. WEIGHT SHIFT IN THIS ACFT IS A MEANS OF FLT CONTROL WITH THE ACFT GOING IN THE DIRECTION OF THE SHIFT.
