## Probable cause

THE PILOT'S INADEQUATE PREFLIGHT PREPARATION OF THE AIRCRAFT, HIS FAILURE TO REMOVE SNOW AND ICE FROM THE AIRCRAFT BEFORE TAKEOFF, AND HIS DELAY IN ATTEMPTING TO ABORT THE TAKEOFF.

## Sequence of events

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

- Overrun, takeoff - aborted
  - aircraft preflight - inadequate, pilot in command (cause)
  - ice/frost removal from aircraft - not performed, pilot in command (cause)
  - abort - delayed, pilot in command (cause)
- On ground/water encounter with terrain/water, takeoff - aborted

## Analysis

THE PILOT INITIATED A TAKEOFF WITH SNOW AND ICE ON THE ACFT. DURING TAKEOFF ROLL THE ACFT BECAME AIRBORNE, SETTLED BACK ONTO THE RUNWAY AND THE PILOT ATTEMPTED TO ABORT THE TAKEOFF. THE ACFT DEPARTED THE END OF THE RUNWAY, IMPACTED NAVIGATION ANTENNAS AND ROUGH TERRAIN.
