## Probable cause

THE PILOT-IN-COMMAND (CFI)'S INADEQUATE SUPERVISION OF THE DUAL STUDENT.

## Sequence of events

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

- Loss of control - in flight, approach - vfr pattern - final approach
  - supervision - inadequate, pilot in command(cfi) (contributing factor)
  - proper alignment - not attained, dual student (contributing factor)
  - proper descent rate - not attained, dual student (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - snowbank (contributing factor)

## Analysis

THE STUDENT WAS OPERATING THE CONTROLS ON FINAL. THE INSTRUCTOR BECAME AWARE THAT THE AIRCRAFT WAS NOT ALIGNED WITH THE CENTERLINE OF THE RUNWAY. HE TOOK CONTROL, BUT WAS UNABLE TO ARREST THE HIGH SINK RATE PRIOR TO IMPACT WITH A SNOWBANK BY THE LEFT MAIN LANDING GEAR. THE AIRCRAFT SUBSEQUENTLY NOSED OVER.
