## Sequence of events

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

- Loss of engine power(partial) - mech failure/malf, takeoff - initial climb
  - fuel system,selector/valve - worn (cause)
  - fluid,fuel - starvation (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, descent
  - terrain condition - high obstruction(s) (contributing factor)
  - clearance - not possible (cause)

## Analysis

SHORTLY AFTER TAKEOFF A LOSS OF POWER OCCURRED AND THE AIRCRAFT STRUCK TREES IN FLIGHT. LESS THAN 1/2 FUEL WAS AVAILABLE IN ALL THREE FUEL TANKS. THE FUEL SELECTOR VALVE WAS TESTED AND FOUND THAT THE SELECTIONS PLATE WAS INDEXED OFF CENTER FOR ALL SELECTIONS DUE TO WEAR. IN THE TAKEOFF ATTITUDE UNPORTING OCCURRED ALLOWING AIR TO BE DRAWN INTO THE SYSTEM.
