## Sequence of events

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

- Loss of control - on ground/water, landing - flare/touchdown
  - weather condition - crosswind (contributing factor)
  - compensation for wind conditions - inadequate, pilot in command (cause)
  - terrain condition - snow covered (contributing factor)
  - proper alignment - not maintained, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - snowbank (contributing factor)

## Analysis

WIND WAS 210 DEGREES AT 13 KNOTS WHEN THE STUDENT PILOT ATTEMPTED A LANDING ON SNOW COMPACTED RUNWAY 12. THE STUDENT STATED THAT A GUST OF WIND PUSHED THE AIRCRAFT SIDEWAYS AND IT STRUCK A SNOWBANK WHEN IT EXITED THE RUNWAY TO THE LEFT.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

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.
