Aircraft involved

Probable cause & findings

WAS FUEL CONTAMINATION. CONTRIBUTING FACTORS ARE THE ENGINE VIBRATIONS AND THE ROUGH VEGETATION UPON WHICH THE AIRPLANE LANDED.

Factual narrative

THE PILOT-IN-COMMAND STATED THAT THE FUEL FLOW BEGAN TO FLUCTUATE AND THE ENGINE BEGAN TO RUN ROUGH. HE SWITCHED FUEL TANKS AND THE ENGINE SMOOTHED OUT. HE THEN SWITCHED BACK TO THE ORIGINAL FUEL TANK AND HE STATED THE ENGINE OIL PRESSURE WENT TO ZERO AND THE ENGINE BEGAN TO VIBRATE. HE ELECTED TO SHUT DOWN THE ENGINE AND EXECUTE A FORCED LANDING. SUBSEQUENT EXAMINATION REVEALED THAT THE ENGINE OIL PUMP WAS WORKING, THAT THERE WAS A SUFFICIENT OIL QUANTITY IN THE ENGINE AND THAT THERE WAS WATER IN THE FULE INJECTOR DISTRIBUTOR.
