NTSB investigators may have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot was attempting to ferry the airplane for friends, who had just purchased it. During the preflight, he checked the fuel, and drained the gascolater for water, but found none. He performed engine checks, and taxi-tested the airplane on the runway several times. He then took off and flew around the airport, then headed toward his destination. Fifteen minutes into the flight, with fuel coming from the left tank, the engine quit. The pilot switched to the right tank, and nothing happened. He pumped the throttle, and the engine ran for about 10 seconds and quit again. He confirmed that the fuel selector was in the detent, then applied carburetor heat. The engine started momentarily, then quit once more, and the pilot performed a forced landing to a grassy field. Upon touchdown, the left main landing gear collapsed, and the airplane nosed over. During post-accident examination, less than 1 gallon of fuel could be drained from the left fuel tank, and the fuel could not be turned off until all fuel was gone from the left tank. An FAA inspector subsequently ran the engine with fuel supplied from the right tank. He also noted that only one header tank was installed, the fuel valve was close to the floor, and the fuel lines were small. The pilot had less than 1 hour of flight time in make and model

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's improper fuel management which resulted in the loss of power, and his improper flare during the forced landing, which resulted in a hard landing. Factors included a restricted fuel supply due to a design flaw in the header tank/fuel valve/supply line combination, and the pilot's lack of experience in airplane make and model.
