## The airworthiness directive

47-43-11 LOCKHEED: (Was Mandatory Note 22 of AD-723-3.) Applies to All Model 18 Serial Numbers.

Compliance required prior to next periodic inspection.

Remove bolts connecting the elevator push-pull rod to the elevator horn and bellcrank and ascertain that the shank diameter falls within the limits of 0.248 to 0.250. Bolts outside these limits should be replaced with NAS 54-12 bolts. In view of the similarity of the Lockheed bolts with standard AN bolt, it is suggested that they be replaced with close tolerance bolts, NAS 54-12 and the push-pull rod. P/N 72149 placarded "Use NAS 54-12 bolt".
