## Sequence of events

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

- Overrun, landing - roll
  - airport facilities,runway/landing area condition - snow covered (contributing factor)
  - airport facilities,runway/landing area condition - icy (contributing factor)
  - unsuitable terrain or takeoff/landing/taxi area - selected, pilot in command (cause)
  - lack of familiarity with aircraft, pilot in command (contributing factor)
- In flight collision with terrain/water, takeoff - initial climb
  - airport facilities,runway/landing area condition - snowbank (contributing factor)
  - go-around - delayed, pilot in command (cause)
- Loss of control - in flight, takeoff - initial climb
  - terrain condition - high obstruction(s) (contributing factor)

## Analysis

DURING ARRIVAL, THE PILOT MADE TWO PASSES OVER THE AIRPORT TO INSURE THAT THE RUNWAY HAD BEEN PLOWED (SNOW REMOVED). HE LANDED ON A 3164 FT RUNWAY IN LIGHT AND VARIABLE WIND CONDITIONS. THE RUNWAY WAS COVERED WITH ICE AND WET SNOW. THE LEFT BRAKE WAS INEFFECTIVE DURING THE LANDING ROLL. TO PREVENT SKIDDING OFF THE RIGHT SIDE OF THE RUNWAY, THE RIGHT BRAKE WAS NOT USED. WHEN THE PILOT SAW AN ICE AND SNOW OBSTRUCTION AT THE END OF THE RUNWAY, HE APPLIED FULL POWER TO GO-AROUND. DURING THE GO-AROUND, THE PLANE STRUCK THE TOP OF A SNOWBANK, THEN STALLED INTO TREES ABOUT 100 FT FROM THE END OF THE RUNWAY. AN INSPECTION AND TEST REVEALED THE LEFT BRAKING ACTION WAS ABOUT 60 TO 65 PERCENT OF THAT OF THE RIGHT BRAKE, BUT SUFFICIENT TO LOCK THE BRAKE.
