## Probable cause

THE PILOT-IN-COMMAND'S IMPROPER PREFLIGHT PLANNING OF FUEL REQUIREMENTS TO ACCOMPLISH THE INTENDED FLIGHT WHICH RESULTED IN AN INADEQUATE FUEL SUPPLY AND SUBSEQUENT LOSS OF ENGINE POWER. A FACTOR WAS THE FENCE.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, cruise
  - single engine aircraft
  - fluid,fuel - exhaustion
  - preflight planning/preparation - inadequate, pilot in command (cause)
  - refueling - not performed, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with object, landing
  - object - fence (contributing factor)
- Nose over, landing - roll

## Analysis

A CESSNA 150K COLLIDED WITH FENCE AND NOSED OVER IN AN OPEN FIELD AFTER A LOSS OF ENGINE POWER. THE PILOT INDICATED THAT THE LOSS OF ENGINE POWER WAS A RESULT OF FUEL EXHAUSTION. THE AIRPLANE TOOK OFF WITH FULL FUEL TANKS. THREE HOURS LATER THE ENGINE LOSS POWER. THE DISTANCE BETWEEN THE DEPARTURE AIRPORT AND THE INTENDED DESTINATION IS ABOUT 344 NM. THE PILOT'S OPERATING HANDBOOK LISTS UNDER THE PERFORMANCE SPECIFICATIONS THE AIRPLANE'S RANGE IS 340 NAUTICAL MILES IN 3.3 HOURS, USING 75 PERCENT ENGINE POWER AT A 7000 FOOT PRESSURE ALTITUDE. FEDERAL AVIATION REGULATIONS DICTATE PILOT'S BEFORE BEGINNING A FLIGHT BECOME FAMILIAR WITH FUEL REQUIREMENTS, AND HAVE ENOUGH FUEL TO FLY TO THE FIRST POINT OF INTENDED LANDING AND FLY AFTER THAT FOR AT LEAST 30 MINUTES.
