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 (MLG).
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect for evidence of missing chrome and corrosion on the chrome surfaces of the forward trunnion bolts (P/N ARG7557-501) on the left and right main landing gears. If corrosion or missing chrome is found, rework the bolt by removing and replating the chrome in accordance with the Component Maintenance Manual or replace the bolt with a serviceable part. Verification of proper chrome plating since original manufacture is required for compliance.
