## Probable cause

THE ACCIDENT WAS THE PIC'S FAILURE TO PROPERLY DETERMINE THE REQUIRED WIDTH OF RUNWAY NEEDED BY THEIR AIRPLANE AND INADEQUATE SNOW REMOVAL.  CONTRIBUTING TO THE ACCIDENT WAS THE SNOW BERM AND THE COPILOT'S MISJUDGMENT OF RUNWAY WIDTH.

## Sequence of events

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

- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - berm (contributing factor)
  - airport snow removal - inadequate, airport personnel (cause)
  - notams - inaccurate, faa(airways facility personnel) (contributing factor)
  - clearance - misjudged, pilot in command (cause)
  - clearance - misjudged, copilot/second pilot (contributing factor)

## Analysis

THE PILOT ATTEMPTED TO GET CURRENT WEATHER AND AIRPORT INFORMATION PRIOR TO AND DURING FLIGHT CONCERNING THE RUNWAY AT SHAGELUK, ALASKA.  THE MOST CURRENT INFORMATION COULD NOT BE CONFIRMED AND THE FLIGHT SERVICE SPECIALIST DID NOT BELIEVE THE INFORMATION WAS CURRENT.  UPON REACHING SHAGELUK, THE CREW OVERFLEW THE AIRPORT AND IT APPEARED TO BE SUITABLE FOR LANDING.  UPON LANDING, THE LEFT PROPELLER STRUCK THE SNOW BERM AND THE AIRPLANE VEERED INTO THE BANK. ACCORDING TO THE FLIGHT CREW, THE RUNWAY WAS PLOWED ONLY 26 TO 35 FEET IN WIDTH.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Incident 19910318005679I](https://openairdocs.org/incident/19910318005679I), Mar 18, 1991: Beech C45H, Shageluk, AK, Minor damage. Nose gear collapsed on landing when aircraft hit deep snow and berm. Not plowed at width given in NOTAM.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
