Install a third AN 3-21 bolt in the existing hold between the two holes now having AN 3-21 bolts in the attachment of the Rudder Pedal Slide Tube Support No. 4118923 and -1, to its Pedal Assembly (5118929, 5118931, and 5118928). If necessary, to correct misalignment among the three holes, it is permissible to use 24ST or 4130 bushing with 1/32-inch wall thickness. This additional bolt is necessary to insure the 100% margin of safety required on the magnesium casting. (Douglas Service Bulletin C-47-101 covers this same subject.) FOOTER:
