## Sequence of events

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

- Loss of control - on ground/water, landing - flare/touchdown
  - touch-and-go - performed, pilot in command
  - directional control - not maintained, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)
  - ground loop/swerve - inadvertent, pilot in command
- On ground/water encounter with terrain/water, landing - roll
  - airport facilities,runway/landing area condition - snowbank (contributing factor)

## Analysis

WHILE THE STUDENT PILOT WAS ON HIS FIFTH TOUCH AND GO PATTERN, THE PLANE VEERED TO THE LEFT AFTER TOUCHDOWN. THE LEFT MAIN GEAR THEN ENCOUNTERED SNOW AND PULLED THE AIRCRAFT FURTHER LEFT INTO A SNOWBANK. THE STUDENT CLAIMED THAT THE OWNERS HAD ADVISED HIM TO APPLY BRAKES AFTER TAKEOFF TO CORRECT A SHIMMY THAT OCCURRED AFTER LIFT-OFF. THE STUDENT BELIEVED THAT THIS CAUSED THE BRAKE TO LOCK. HOWEVER, THE BRAKE WAS NOT LOCKED WHEN THE PLANE WAS REMOVED FROM THE SNOWBANK, AND IT OPERATED NORMALLY WHEN CHECKED. THERE WAS A RIGHT QUARTERING HEADWIND AT 8 KNOTS.
