## Probable cause

COMPENSATION FOR WIND WAS INADEQUATE ANAD DIRECTIONAL CONTROL NOT MAINTAIN BY THE PIC.  CONTRIBUTING FACTORS WERE: SNOW COVERED RUNWAY, GUSTY CROSSWIND, AND A SNOWBANK.

## 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 - snow covered (contributing factor)
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - compensation for wind conditions - inadequate, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - snowbank (contributing factor)
- Nose over, landing - roll

## Analysis

WHILE THE STUDENT PILOT WAS ATTEMPTING TO LAND ON A SNOW PACKED RUNWAY, WITH A GUSTY CROSSWIND, DIRECTIONAL CONTROL WAS LOST ON THE ROLL OUT AND THE AIRCRAFT VEERED OFF THE RUNWAY AND NOSED OVER.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
