Analysis

The acft collided with a dirt bank during a forced landing after the engine quit. The plt said he was making a swath runwhen the engine quit. The flagman said he saw black smoke then white smoke as the engine quit. Post crash investigation revealed that the float fulcrum screw (p/n P13773) had backed out of the carburetor assembly. This would result in engine flooding. The screw was found in the cowling after the accident. According to the manufacturer the screw is initially safetied to a pipe plug. If installed in an acft with a fuel pressure gauge this pipe plug is removed so the screw has to be resafetied.
