## Sequence of events

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

- In flight collision with terrain/water, landing - flare/touchdown
  - weather condition - unfavorable wind (contributing factor)
  - weather condition - windshear (contributing factor)
  - compensation for wind conditions - improper, pilot in command (cause)
  - terrain condition - snowbank (contributing factor)

## Analysis

THE PILOT REPORTED THAT DURING A BASE TO FINAL TURN, THE AIRCRAFT WAS BLOWN SLIGHTLY OFF THE CENTER LINE OF THE RUNWAY. ALSO, HE REPORTED ENCOUNTERING A WIND SHEAR EFFECT FROM A NEARBY BLUFF. AS THE PLANE DRIFTED TO THE RIGHT, IT COMMENCED A HIGH SINK RATE AND THE PILOT ADDED POWER. HOWEVER, THE RIGHT MAIN LANDING GEAR STRUCK A SNOWBERM AT THE EDGE OF THE RUNWAY. THE PLANE CONTINUED IN A RELATIVELY STRAIGHT LINE FOR ABOUT 75 TO 80 FT, THEN NOSED OVER.
