## Probable cause

THE PILOT-IN-COMMAND'S IMPROPER IN-FLIGHT PLANNING AND ULTIMATE FUEL EXHAUSTION.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, cruise
  - fluid,fuel - exhaustion (cause)
  - in-flight planning/decision - improper, pilot in command (cause)
- Forced landing, descent - emergency
- Forced landing, landing - flare/touchdown
  - terrain condition - none suitable (cause)

## Analysis

THE PILOT STATED THAT THE AIRPLANE RAN OUT OF FUEL DURING THE FLIGHT. THE PILOT THEN MADE AN EMERGENCY LANDING ON THE TUNDRA. THE AIRPLANE WAS SUBSTANTIALLY DAMAGED. THE PILOT AND PASSENGER WERE NOT INJURED.
