## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - weather condition - crosswind
  - compensation for wind conditions - inadequate, pilot in command (cause)
  - lack of familiarity with aircraft, pilot in command (contributing factor)
  - ground loop/swerve - uncontrolled, pilot in command (cause)
- On ground/water collision with object, landing - roll
  - object - tree(s)

## Analysis

WHILE LANDING AT A 1,900' SOD AIRSTRIP WITH A 10 KNOT CROSSWIND, THE AIRCRAFT SWERVED TO THE LEFT, RAN OFF THE RUNWAY AND STRUCK SOME SMALL TREES AND SHRUBS. THE PILOT LACKED TOTAL EXPERIENCE IN LOW WING AIRCRAFT AND LACKED FAMILIARITY WITH THAT PARTICULAR AIRCRAFT.
