## The airworthiness directive

47-21-14 REPUBLIC: (Was Mandatory Note 4 of AD-769-2.) Applies only to Model RC-3 Aircraft Serial Numbers 5 to 500, Inclusive.

Compliance required at the next 25-hour inspection or by August 1, 1947, whichever occurs first.

To prevent fouling of the lower elevator cable on the elevator balance weight in the tail boom, incorporate Republic SK-17-14052-2 in the lower elevator control cable system. This elevator control cable guide is installed on the cross channel, in the tail boom, with the existing bolts holding the two inboard rudder pulley brackets.

(Republic Service Bulletin No. 14 dated March 31, 1947, covers the same subject.)
