## Probable cause

THE PILOT FAILED TO MAINTAIN DIRECTIONAL CONTROL. CONTRIBUTING TO THE ACCIDENT WAS THE GUSTY CROSSWINDS AND SLIPPERY RUNWAY.

## 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
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - airport facilities,runway/landing area condition - icy (contributing factor)
  - directional control - not maintained, pilot in command (cause)
- Dragged wing,rotor,pod,float or tail/skid, landing - roll
  - directional control - not maintained, pilot in command (cause)

## Analysis

THE PILOT STATED THAT HE EXPERIENCED CROSSWINDS OF ABOUT 15 KNOTS, WHICH CAUSED THE AIRPLANE TO BE BLOWN OFF THE SIDE OF THE RUNWAY DURING THE LANDING ROLL. THE SNOW-COVERED RUNWAY WAS ALSO REPORTED TO HAVE BEEN RECENTLY PLOWED AND SLIPPERY. AT THE TIME OF THE ACCIDENT, THE PILOT WAS RETURNING HOME AFTER SATISFACTORILY COMPLETING HIS COMMERCIAL AIRPLANE CHECK RIDE ABOUT AN HOUR EARLIER.
