Probable cause

The inadequate annual inspection of the fuel system that failed to detect a deteriorated fuel line and a misrigged fuel selector, which resulted in fuel starvation and a subsequent total loss of engine power. Contributing to the accident was the mechanic’s failure to verify the work completed by the owner before endorsing the annual inspection.

NTSB narrative

The airline transport pilot was conducting the first flight in the airplane after an extended period of inactivity. The pilot reported that, about 10-15 minutes after takeoff, the engine sputtered. He applied carburetor heat and checked the position of the fuel selector and the magnetos. The engine operation smoothed out; however, a short time later, the engine experienced a total loss of power. The pilot conducted a forced landing in a corn field, which resulted in substantial damage to the airframe. A postaccident examination of the airplane revealed the fuel line between the fuel strainer and the carburetor was deteriorated and leaking fuel, and the fuel selector was rigged in such a way that it would only open about 25%, which limited the amount of fuel flowing to the engine. The mechanic who signed off the airplane's most recent annual inspection, which was completed the month before the accident, reported that the airplane's owner assisted with the inspection, and that he did not verify the owner's work before endorsing the annual inspection.
