Accident Overview
An aircraft crashed while attempting a forced landing after its engine quit during flight. The aircraft had previously experienced a forced landing, and the fuel pump had been suspected as a potential issue.
Investigation Findings
Post-accident investigation determined that only one safety pin was installed in the fuel selector shaft, resulting in excessive free play. Additionally, the gascolator had a leaking gasket, which allowed air to enter the fuel system and caused the engine stoppage.
Maintenance History
During the last annual inspection, conducted two months prior to the accident, the leaking gasket was discovered. The aircraft owner did not replace it because he was unable to find a replacement part.
