## Probable cause

THE PILOT-IN-COMMAND'S IMPROPER PREFLIGHT PREPARATION AND PLANNING. CONTRIBUTING TO THE ACCIDENT WAS UNSUITABLE TERRAIN.

## Sequence of events

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

- On ground/water encounter with terrain/water, takeoff - roll/run
  - terrain condition - rough/uneven (cause)
  - preflight planning/preparation - improper, pilot in command (cause)
  - unsuitable terrain or takeoff/landing/taxi area - selected, pilot in command (cause)

## Analysis

DURING THE TAKEOFF ROLL, THE AIRPLANE STRUCK SEVERAL LARGE ROCKS CAUSING THE MAIN LANDING GEAR TO TEAR AWAY FROM THE FUSELAGE. AS A RESULT OF THE MAIN LANDING GEAR BEING RIPPED AWAY, THE AIRPLANE'S MAIN WING SPAR AND STABILATOR WERE DAMAGED. AFTER THE PILOT DEPARTED THE BEACH AREA, HE FLEW DIRECTLY BACK TO KING SALMON AIRPORT.
