## Probable cause

THE PILOT FAILED TO PROPERLY ALIGN THE AIRPLANE ON THE RUNWAY FOR LANDING, THEN FAILED TO MAINTAIN DIRECTIONAL CONTROL AFTER LANDING. CONTRIBUTING TO THE ACCIDENT WAS THE PILOTS OPERATION OF THE AIRPLANE WITH AN INOPERATIVE LANDING LIGHT AND THE DARK NIGHT CONDITIONS.

## 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
  - landing light(s) - inoperative (contributing factor)
  - proper alignment - not attained, pilot in command (cause)
  - terrain condition - berm
  - directional control - not maintained, pilot in command (cause)
  - operation with known deficiencies in equipment - improper, pilot in command (contributing factor)
  - light condition - dark night (contributing factor)
- On ground/water encounter with terrain/water, landing - roll

## Analysis

THE PILOT LOST DIRECTIONAL CONTROL OF THE AIRPLANE WHICH COLLISED WITH A SNOWBERM AFTER LANDING WITH INOPERATIVE LANDING AND TAXI LIGHTS ON A DARK NIGHT. THE AIRPLANE TOUCHED DOWN ABOUT 20 FEET LEFT OF THE CENTER OF THE RUNWAY, WITH THE LEFT MAIN WHEEL 2-3 FEET FROM A 2-3 FOOT DEEP SNOWBERM ALONG THE LEFT SIDE OF THE RUNWAY.
