Unsafe Condition
Chrome flaking on the bearing surface of the trunnion bolts due to improper cleaning of the base material prior to chrome plating, leading to severe corrosion on the bearing surface and in the mechanical fuse, which could cause premature failure of the trunnion bolts and subsequent collapse of the main landing gear.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect the forward trunnion bolts on the main landing gear to determine their serial number (for MD-11 series) or for evidence of missing chrome, corrosion on chrome surfaces, or verification of chrome plating (for DC-10-30, DC-10-40, and KC-10A). Rework or replace the bolts as necessary. Installation of specific part numbers (ARG7558-507 for DC-10 series, ARG7558-509 or ARG7008-511 for MD-11 series) constitutes terminating action.
