## Probable cause

PILOT-IN-COMMAND'S FAILURE TO MAINTAIN AIRPLANE CONTROL.

## Sequence of events

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

- Loss of control - in flight, approach
  - aircraft control - not maintained, pilot in command (cause)
- In flight collision with terrain/water, approach

## Analysis

DURING AN APPROACH TO LAND, THE PILOT LOST CONTROL OF THE AIRPLANE. THE AIRPLANE THEN STALLED AND CRASHED ON TUNDRA. THE AIRPLANE WAS SUBSTANTIALLY DAMAGED AND THE PILOT WAS NOT INJURED.
