Notice of proposed rulemaking (NPRM).
Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A321-251NX, -252NX, -253NX, -271NX, and -272NX airplanes. This proposed AD was prompted by the discovery during a quality review performed during manufacturing, that a torque strip indicator (material "Dykem") had been applied on the orifice fitting on certain slides' inflation reservoirs' venting holes. This proposed AD would require an inspection for discrepancies of affected parts (certain reservoirs having certain orifices) and replacement of discrepant affected parts, and would prohibit installing affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
