## The airworthiness directive

47-21-03 FAIRCHILD: (Was Mandatory Note 9 of AD-707-2 and Mandatory Note 6 of AD-706-1.) Applicable to Models F24W-41A. Serial 373 and Up, and All Models F24W46, F24W46S, F24R46, F24R46A and F24R46S Aircraft.

Compliance required before August 1, 1947.

Inspect forward rudder cable turnbuckles which attach to idler brackets located in lower fuselage truss aft of baggage compartment. Turnbuckles should swivel freely. Turnbuckle eyes with shank bent or filed down or which are otherwise damaged should be replaced. Select an eye which swivels freely in idler bracket and use a clevis bolt of sufficient length to prevent binding. If shank of eye is bent, check alinement of rudder cable.

(Fairchild Service Bulletin No. 47-24-2 dated April 22, 1947, covers this same subject.)
