## Probable cause

A LOSS OF CONTROL DURING LANDING WHEN THE AIRCRAFT STRUCK A SNOWBANK WHICH WAS LEFT ON THE RUNWAY AS A RESULT OF INADEQUATE PLOWING.

## Sequence of events

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

- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - snow covered
  - terrain condition - snowbank (cause)
  - airport snow removal - inadequate, airport personnel (cause)
- Nose over, landing - roll

## Analysis

DURING A NIGHT FLIGHT, A SNOW PLOW CLEANED THE RUNWAY.  THE PLOWING WAS DONE OFF CENTER AND DID NOT ENCOMPASS THE FULL WIDTH OF THE RUNWAY, THUS LEAVING A SNOWBANK ON THE RUNWAY. WHEN THE FLIGHT LANDED, THE LEFT MAIN GEAR WAS IN THE SNOWBANK CAUSING THE AIRCRAFT TO SWERVE TO THE LEFT. WHEN THE NOSE GEAR CONTACTED THE SNOWBANK, THE AIRCRAFT NOSED OVER.
