## Probable cause

THE ICY AND SNOW COVERED CONDITION OF THE RUNWAY SURFACE AND THE PILOT'S INADEQUATE PREFLIGHT PLANNING AND PREPARATION BY NOT SURVEYING THE SURFACE OF THE ENTIRE RUNWAY.

## Sequence of events

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

- Overrun, takeoff - aborted
  - terrain condition - icy (cause)
  - terrain condition - snow covered (cause)
  - preflight planning/preparation - inadequate, pilot in command (cause)

## Analysis

THE PILOT ATTEMPTED TO TAKEOFF WITH 6 INCHES OF CRUSTED SNOW ON THE RUNWAY.  HE STATED HE WAS NOT ABLE TO ATTAIN FLYING SPEED AND HE ELECTED TO ABORT THE TAKEOFF.  AFTER REDUCING THE POWER TO THE IDLE POSITION, HE WAS UNABLE TO STOP ON THE REMAINING RUNWAY.  THE DEPARTURE END OF THE RUNWAY WAS COVERED WITH 2 INCHES OF CLEAR ICE AND THEN 2 MORE INCHES OF POWDERED SNOW.  THE PILOT STATED HE DID NOT CHECK THE DEPARTURE END OF THE RUNWAY BEFORE ATTEMPTING TO TAKEOFF.
