## Probable cause

DUAL STUDENT'S INADEQUATE COMPENSATION FOR WIND CONDITIONS AND REMEDIAL ACTION NOT ATTAINED BY THE CFI. A FACTOR RELATED TO THE ACCIDENT WAS: A SNOW BANK ADJACENT THE RUNWAY.

## Sequence of events

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

- Dragged wing,rotor,pod,float or tail/skid, takeoff - initial climb
  - compensation for wind conditions - inadequate, dual student (cause)
  - remedial action - not attained, pilot in command(cfi) (cause)
- In flight collision with terrain/water, takeoff - initial climb
  - terrain condition - snowbank (contributing factor)

## Analysis

THE DUAL STUDENT WAS ATTEMPTING A SHORT-FIELD TAKEOFF IN PREPARATION FOR COMMERCIAL CERTIFICATION. AN INSTRUCTOR OCCUPIED THE RIGHT SEAT. THE STUDENT AND INSTRUCTOR STATED A WIND GUST AT LIFTOFF RAISED THE RIGHT WING AND DISPLACED THE AIRPLANE LEFT. THE LEFT WINGTIP DRAGGED SNOW-COVERED GROUND ALONGSIDE THE RUNWAY, PIVOTING THE AIRPLANE LEFT AND NOSE DOWN TO A STOP. TAKEOFF RUNWAY WAS 24; WINDS WERE VARIABLE 240 TO 270 DEGREES AT 10 KNOTS, GUSTING TO 15.
