## Probable cause

THE PILOTS FAILURE TO PROPERLY CALCULATE FUEL CONSUMPTION WHICH RESULTED IN AN INADEQUATE FUEL RESERVE AND FUEL EXHAUSTION PRIOR TO REACHING HIS DESTINATION. DURING THE ENSUING FORCED LANDING THE PILOT FAILED TO MAINTAIN AIRSPEED WHICH RESULTED IN AN INADVERTANT STALL INTO TREES WHILE TRYING TO FLY TO THE RUNWAY. CONTRIBUTING TO THE ACCIDENT WAS THE PILOTS FAILURE TO PERFORM A PRECAUTIONARY LANDING AT A CLOSER AIRPORT WHEN HE HAD THE OPPORTUNITY.

## 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
  - fuel consumption calculations - misjudged, pilot in command (cause)
  - precautionary landing - not performed, pilot in command (contributing factor)
- Forced landing, descent - emergency
- In flight collision with terrain/water, descent - uncontrolled
  - airspeed - not maintained, pilot in command (cause)
  - terrain condition - none suitable (contributing factor)
  - stall - inadvertent, pilot in command (cause)
- Nose over, descent - uncontrolled

## Analysis

THE PILOT SAID THAT DURING THE LAST LEG OF A STUDENT, SOLO CROSS-COUNTRY TRIP, THE ENGINE BEGAN TO TO MIS-FIRE ABOUT 25 MILES FROM HIS DESTINATION ARPT. HE APPLIED CARB HEAT AND RICHENED THE MIXTURE, WHICH RESTORED NORMAL ENGINE OPERATION. ABOUT 6 MILES FROM DESTINATION, THE ENGINE ONCE AGAIN BEGAN MISSING AND APPLICATION OF CARB HEAT DID NOT RESOLVE THE PROBLEM. ABOUT 3 MILES FROM THE DESTINATION ARPT, THE ENGINE FAILED COMPLETELY. AN EMERGENCY LDG WAS ATTEMPTED ON THE ARPT, BUT THE AIRCRAFT STALLED AND CRASHED SOUTHEAST OF THE INTENDED RUNWAY. THE ACFT COLLIDED WITH TREE TOPS, THEN STRUCK THE WET, MARSHY TERRAIN AND OVERTURNED. POST ACCIDENT INVESTIGATION REVEALED THE ENGINE STOPPED DUE TO FUEL EXHAUSTION. THE ACFT HAD BEEN AIRBORNE FOR APRX 1 HOUR SINCE THE LAST TAKEOFF POINT.
