Action
Final rule.
Summary
We are adopting a new airworthiness directive (AD) for all Airbus Model A318-111, and -112 airplanes; Model A319-111, -112, -113, -114, and -115 airplanes; Model A320-211, -212 and -214 airplanes; and Model A321-111, -112, -211, -212, and -213 airplanes. This AD was prompted by a report of a production quality deficiency on the inner retainer installed on link assemblies of the aft engine mount, which could result in failure of the retainer. This AD requires an inspection for, and replacement of, all non-conforming aft engine mount retainers. We are issuing this AD to address the unsafe condition on these products.
