## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2025-16-12, which applies to all Airbus SAS Model A319-151N, -153N, - 171N, and -173N airplanes; Model A320-251N, -252N, -253N, -271N, -272N, and -273N airplanes; and Model A321-251N, -252N, -253N, -271N, -272N, - 251NX, -252NX, -253NX, -271NX, -272NX, -253NY, and -271NY airplanes. AD 2025-16-12 requires revising the existing airplane flight manual (AFM) and the existing FAA-approved minimum equipment list (MEL), allows replacement of each affected high-pressure bleed valve (HPV) as an optional terminating action, and prohibits the installation of affected parts. Since the FAA issued AD 2025-16-12, the FAA has determined repetitive replacement of the HPV clips is necessary to address the unsafe condition. This proposed AD would continue to require the actions in AD 2025-16-12 and would require repetitive replacement of each affected HPV clip. The FAA is proposing this AD to address the unsafe condition on these products.
