## The airworthiness directive

59-14-02 MOONEY: Applies to M-20 Airplanes Serial Numbers 1175 Through 1200 and M-20A Airplanes Serial Numbers 1201 Through 1375. Compliance required prior to August 1, 1959. To guard against fuel selector valve failure and inability to change selector valve position the following inspection and replacement is required prior to August 1, 1959. Replacement valves obtained from the factory after April 27, 1959, and installed need not comply with this AD. (a) Remove fuel tank selector valve. (b) Remove lower part of valve housing and remove plastic core. (c) Determine if the shaft and plastic core are pinned together. If not, replace complete valve assembly with replacement valve P/N 311-221-1/4D obtained from Mooney. (Mooney Service Letter 20-48 concerns this subject.)
