AD 95-18-12 60 FR 47683

This amendment adopts a new airworthiness directive (AD) that applies to Mooney Aircraft Corporation (Mooney) Model M20K airplanes. This action requires inspecting to see if the airplane is equipped with a Gerdes fuel selector valve, part number (P/N) A-2580, and replacing any Gerdes fuel selector valve with an Airight fuel selector valve. Malfunction of a Gerdes fuel selector valve on an affected airplane, where the valve did not allow the operator to select the appropriate fuel tank, prompted this action. The actions specified by this AD are intended to prevent fuel selector valve malfunction, which, if not detected and corrected, will prevent the airplane operator from selecting the appropriate fuel tank, resulting in an unscheduled landing.
