## Probable cause

THE STUDENT PILOT'S IMPROPER FLARE TECHNIQUE AND USE OF RUDDER.

## 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
  - flare - improper, pilot in command (cause)

  - rudder - improper use of, pilot in command (cause)
  - directional control - not maintained, pilot in command
- On ground/water collision with object, landing - roll

## Analysis

THE 30 HOUR STUDENT PILOT STATED THAT HE LANDED FAST AND TOUCHED DOWN NOSE GEAR FIRST. THE AIRPLANE SUBSEQUENTLY WHEEL BARROWED DOWN THE RUNWAY AND THE STUDENT APPLIED LEFT RUDDER. THE AIRPLANE THEN DEPARTED THE LEFT SIDE OF THE RUNWAY AND THE LEFT WING COLLIDED WITH THE VASI SYSTEM.
