## Probable cause

PILOT-IN-COMMAND'S FAILURE TO MAINTAIN AIRCRAFT CONTROL DURING LANDING.

## 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
  - aircraft control - not maintained, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - tundra

## Analysis

AFTER TOUCHDOWN ON THE GRAVEL LANDING AREA, THE PILOT LOST CONTROL OF THE AIRPLANE. THE AIRPLANE RAN OFF THE DEPARTURE END INTO THE TUNDRA. AT THE TIME OF THE ACCIDENT SNOW COVERED THE LAST THIRD OF THE LANDING AREA.

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.
