Narrative:
THE FLIGHT WAS EN ROUTE TO PORTLAND OVER MOUNTAINOUS TERRAIN. AT 0940, THE U.S. FOREST SERVICE WAS NOTIFIED OF A FIRE AND THE AIRCRAFT WRECKAGE WAS SUBSEQUENTLY LOCATED IN A SADDLE AT THE 6,480-FOOT LEVEL. THE ACCIDENT SITE IS THE ONLY RELATIVELY CLEAR AREA IN THE VICINITY. AT 1000, A HELICOPTER REACHED THE ACCIDENT SITE AND DROPPED WATER ON THE BURNING WRECKAGE. THE WRECKAGE WAS FOUND WITHIN A 23-FOOT-DIAMETER AREA. AN EXAMINATION OF THE AIRCRAFT WRECKAGE REVEALED DAMAGE CONSISTENT WITH A LOW-SPEED, MODERATE-ANGLE CONTROLLED IMPACT. THE AIRCRAFT'S ENGINE HAD BEEN MODIFIED TO OPERATE ON 87 OCTANE AUTO FUEL. AN INSPECTION REVEALED THE SPARK PLUGS WERE WORN, WITH THE ELECTRODES FOUND TO HAVE A GAP IN EXCESS OF .022 OF AN INCH. NONE OF THE SPARK PLUGS WERE FOULED. THE FUEL INLET SCREEN EXHIBITED A DARK, WET SUBSTANCE. A THREAD COMPOUND WAS PRESENT AND ON THE FUEL INLET SCREEN. THE CARBURETOR HAD COMPOSITE FLOATS INSTALLED. THE TWO-PIECE VENTURI WAS FOUND DISPLACED IN THE CARBURETOR THROAT. A LINEMAN AT LINCOLN HAD SEEN THE AIRCRAFT BEING FUELED FROM SEVERAL CANS THE DAY PRIOR TO ITS DEPARTURE FROM THE LINCOLN AIRPORT. CAUSE: a loss of engine power for undetermined reasons. The mountainous terrain and lack of a suitable forced landing area within gliding distance was a factor in the accident.
