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

- Loss of control - on ground/water, landing - roll
  - weather condition - gusts (contributing factor)
  - directional control - not maintained, pilot in command (cause)
- On ground/water collision with object, landing - roll
  - terrain condition - berm (contributing factor)

## Analysis

UPON OVERFLYING THE AIRPORT THE STUDENT PILOT DETERMINED THAT THE WINDS FAVORED A RIGHT CROSSWIND LANDING ON RUNWAY 2. UPON APPLICATION OF POWER DURING THE TOUCH AND GO THE AIRCRAFT SWERVED TO THE RIGHT AND THE PILOT WAS UNABLE TO MAINTAIN DIRECTIONAL CONTROL. THE PILOT ALLOWED THE AIRCRAFT TO ROLL OFF THE RUNWAY DURING WHICH IT IMPACTED AN EARTHEN BERM. THE PILOT REPORTED A CROSSWIND OF 5 TO 10 KNOTS FROM 090 DEGREES AT THE TIME OF THE ACCIDENT.
