The airworthiness directive
47-02-02 DOUGLAS: (Was Mandatory Note 10 AD-762-7.) Applies to All C-54 Series Aircraft and DC-4 Aircraft, Serial Numbers 42904 to 42943, Inclusive; 42948 to 42952, Inclusive; 42982 to 42996, Inclusive; and 43065.
To be accomplished not later than July 1, 1947.
Inspect the clevis shear bolts in the vertical stabilizer forward attach fitting (Station 953), P/N 4106204 and -1, for loose or stretched bolts. In some instances, the lower 3/16-inch bolts, when being checked for tightness, have broken. In order to overcome the difficulty, the stabilizer attaching fittings should be reworked and bolts be replaced with high heat-treated bolts.
(Douglas Service Bulletin DC-4 No. 11, covers this same subject.)
