Following an uneventful takeoff and straight-out departure, the pilot leveled the Corben Baby Ace D about 1,000 feet above ground level, at which point, the engine began to sputter, and it subsequently lost power.
The pilot initiated a return to the airport, however, due to the low altitude, he initiated a forced landing to a nearby field in Lincoln, Calif.
During the landing, the main landing gear collapsed, and the airplane nosed over.
Post-accident examination of the airplane revealed that the gascolator screen and fuel outlet port were partially restricted with red, sandlike debris, which would have restricted the fuel flow to the carburetor and led to the loss of engine power.
The NTSB determined the probable cause as the total loss of engine power due to fuel starvation, which resulted from debris restricting the fuel flow within the fuel system.
NTSB Identification: WPR15LA003
