## Probable cause

THE CERTIFIED FLIGHT INSTRUCTOR'S INABILITY TO REGAIN DIRECTIONAL CONTROL AFTER IT WAS LOST BY HIS DUAL STUDENT ON AN ICY, SNOWY RUNWAY.

## 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
  - terrain condition - icy
  - directional control - not maintained, dual student (cause)
  - terrain condition - snow covered
  - relinquishing of control - not obtained, pilot in command(cfi) (cause)
- Nose over, landing - roll

## Analysis

THE CERTIFIED FLIGHT INSTRUCTOR ATTEMPTED TO CORRECT HIS STUDENT'S LEFT DRIFT FROM THE RUNWAY CENTERLINE BY VERBAL CAUTION. WHEN THAT FAILED, HE ATTEMPTED TO TAKE CONTROL OF THE AIRCRAFT, BUT WAS UNABLE TO OVERPOWER HIS STUDENT'S LEFT RUDDER INPUT. THE AIRCRAFT DRIFTED OFF THE LEFT SIDE OF THE RUNWAY AND NOSED OVER IN A SNOWBANK.
