## Probable cause

PARTIAL LOSS OF ENGINE POWER DUE TO FUEL EXHAUSTION DUE TO MISJUDGED FUEL CONSUMPTION CALCULATIONS.

## 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)
  - fuel consumption calculations - misjudged, pilot in command (cause)
- Forced landing, descent - emergency
  - object - sign
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE ACFT DEPARTED WITH FULL FUEL TANKS & WHEN THE FLT WAS APRX 12 MILES FROM THE DESTINATION ARPT THE ENG BEGAN SURGING. UNABLE TO MAINTAIN ALTITUDE THE PLT ELECTED TO PERFORM A LANDING IN A FIELD BUT DURING THE DESCENT, THE LT WING COLLIDED WITH A POLE. THE ACFT THEN LANDED & CAME TO REST UPRIGHT. THE FUEL TANKS WERE DRAINED WHICH REVEALED THAT THEY CONTAINED 3.25 GALS. THE UNUSABLE FUEL QUANTITY IS 1.5 GALS. AN A&P MECHANIC EXAMINED THE ENG & FOUND NO RESONS FOR THE FAILURE/MALFUNCTION.
