## Probable cause

IMPROPER FUEL TANK SELECTOR POSITION OF BOTH ENGINES RESULTING IN TOTAL LOSS OF ENGINE POWER DUE TO FUEL STARVATION. ALSO, FAILURE OF THE PILOT TO PERFORM THE EMERGENCY PROCEDURES FOLLOWING THE LOSS OF POWER FROM BOTH ENGINES.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, cruise - normal
  - all engines
  - fluid,fuel - starvation
  - fuel tank selector position - improper, pilot in command (cause)
  - emergency procedure - not performed, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with object, descent - uncontrolled
  - object - tree(s)
  - object - pole

## Analysis

DURING CRUISE FLT TO RETURN TO THE DEPARTURE ARPT, THE RT ENG QUIT DUE TO FUEL STARVATION.  THE PLT DID NOT FEATHER THE PROPELLER NOR SECURE THE ENG.  HE WAS ADVISED OF A NEARBY ARPT & DIVERTED TO LAND THERE BUT THE LT ENG QUIT DUE TO FUEL STARVATION.  DURING THE DESCENT THE ACFT COLLIDED WITH A TREE & POWER LINE POLE.  THE PLT STATED THAT HE DID NOT REPOSITION THE FUEL SELECTORS AFTER EACH ENG QUIT.

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.
