The airworthiness directive
46-11-03 DOUGLAS: (Was Mandatory Note 2 of AD-762-7.) Applies Only to All C54-DC (R5D) Airplanes Built at Santa Monica and to All C54A (R5D-1), C54B (R5D-2) and C54D-DC (R5D-3) Airplanes Built at Chicago Up to and Including C54D-DC AAF Serial Number 42-72698, and R5D-3 Navy Serial No. 56519. All Subsequent Airplanes Have Been Reworked Prior to Delivery by the Douglas Co.
To be accomplished not later than next engine change.
Due to the possibility of the landing gear door stud shearing and preventing the landing gear from extending, the old thin stud, Douglas Drawing No. 1167048 should be replaced with the new thick stud, Douglas Drawing No. 1329227. In order to accomplish this change the thin stud should be removed from each landing gear door sleeve assembly, P/N 4167071. The existing stud hold should be drilled to +.4459,- .4531 diameter and tapped 1/2-20 NF-3 to a depth of 1/2 inch. The new thick stud, Douglas P/N 1329227 should be installed and locked in place with an 0.063-inch drill rod pin 3/8-inch long pressed through the side of the sleeve assembly end, Drawing No. 2167063.
(Douglas Service Bulletin No. C-54-275 dated January 21, 1946, covers this same subject.)
