Airworthiness Directives; Mooney Aircraft Corporation Model M20K Airplanes

Zusammenfassung

This document proposes to adopt a new airworthiness directive (AD) that would apply to Mooney Aircraft Corporation (Mooney) Model M20K airplanes. The proposed action would require 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 the proposed action. The actions specified by the proposed AD are intended to prevent fuel selector valve malfunction, which, if not detected and corrected, would prevent the airplane operator from selecting the appropriate fuel tank, resulting in an unscheduled landing.
