Unsafe Condition
Reports of quality non-conformity on main landing gear (MLG) axles where the HVOF coating on the bearing journal runout areas had a coating thicker than allowable limits. This over-thickness could lead to damage, cracking, or spalling of the protective coating, which could expose the base material and allow corrosion to develop, potentially resulting in MLG axle failure and MLG collapse.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Repetitive inspections of the affected MLG axles for any discrepancy, including damage, cracking, or spalling of the HVOF coating, or corrosion. Corrective actions, including obtaining and following repair instructions, and eventual replacement of affected parts. Prohibition of the installation of affected parts or MLGs having an affected part installed.
