Summary
The FAA proposes to supersede Airworthiness Directive (AD) 2018-16-02, which applies to all Airbus SAS Model A318-111 and -112 airplanes, Model A319-111, -112, -113, -114, and -115 airplanes, Model A320-211, -212, -214, and -216 airplanes, and Model A321-111, -112, - 211, -212, and -213 airplanes. AD 2018-16-02 requires modifying and re- identifying the aft engine mount assemblies. Since the FAA issued AD 2018-16-02, a modification has been developed for 4-lug engines that the FAA has determined is necessary. This proposed AD would retain the requirement to modify and re-identify the 3-lug aft engine mount assemblies and would include a new requirement to modify and re- identify the 4-lug aft engine mount assemblies, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
