Analysis

THE PLT SWITCHED FROM MAIN TANK TO AUX TANK, & ABOUT 10 MINUTES LATER, THE ENG BEGAN LOSING POWER SWITCHING BACK TO THE MAIN TANK DID NOT HELP. THE ENGINE CONTINUED RUNNING BUT AT GREATLY REDUCED POWER. A FORCED LANDING WAS MADE IN A FROZEN STUBBLE FIELD. THE PLT SAID HE DRAINED ABOUT 3 OUNCES OF WATER OUT OF THE MAIN FUEL STRAINER AFTER THE ACCIDENT. NO FUEL LINES WERE BROKEN AND NO TANKS RUPTURED. INVESTIGATORS FOUND VERY LITTLE FUEL IN THE CARBURETOR AND WHAT WAS FOUND WAS CONTAMINATED WITH DIRT AND DEBRIS.
