## 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
  - supervision - inadequate, pilot in command(cfi) (cause)
  - directional control - not maintained, dual student (cause)
  - lack of total experience, dual student (contributing factor)
  - ground loop/swerve - inadvertent, dual student
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - rough/uneven (contributing factor)

## Analysis

THE STUDENT PILOT LOST DIRECTIONAL CONTROL DURING THE LANDING ROLL. THE INSTRUCTOR PILOT WAS UNABLE TO REGAIN CONTROL TO PREVENT A GROUND LOOP. SUBSEQUENTLY, THE ACFT VEERED OFF THE RWY & WAS DAMAGED ON ROUGH TERRAIN.
