The airworthiness directive
51-03-01 MOONEY: Applies to Model M-18 Series Aircraft, Serial Numbers 1 Through 82 and 201 Through 236. Compliance required not later than March 15, 1951. There have been reported failures of the fuel line due to vibration and relative motion between the fuel tank and the fuel shutoff valve. To preclude the possibility of recurrence of this type failure, cut the fuel line at a point approximately 4 inches from the fuel tank outlet and install a 4-inch length of 3/8-inch ID approved aromatic resistant flexible hose and hose clamps at this point. (Mooney Service Bulletin No. 6 covers this same subject.)
