47-47-08: Fuel Line Chafing

47-47-08 BEECH: (Was Mandatory Note 2 of AD-777-1.) Applies to Model 35 Serial Numbers D210 to D558 Inclusive, D560 to D574 Inclusive, D580 to D668 Inclusive, and D670 to D678 Inclusive. Compliance required as soon as possible but not later than January 15, 1948. To prevent the top carburetor baffle from cutting through the aluminum alloy fuel line located between the engine driven fuel pump and the carburetor, remove the rubber grommet in this baffle and enlarge the cut out in the baffle for the grommet to permit a minimum of 1/2 inch clearance between the fuel line and the baffle. No grommet is required for the above modification. Inspect the fuel line for chafing or wear at the point where the line passes through the baffle. If necessary, replace the line with a new part, Beech P/N 35-924058 or the equivalent. (Beech Service Bulletin No. 35-4 covers this same subject.)
