What the agency says
The FAA is superseding Airworthiness Directive (AD) 2025-16- 12, which applied 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 required revising the existing airplane flight manual (AFM) and the existing FAA-approved minimum equipment list (MEL), allowed replacement of each affected high-pressure bleed valve (HPV) as an optional terminating action, and prohibited the installation of affected parts. Since the FAA issued AD 2025-16-12, the FAA has determined that repetitive replacement of the HPV clips is necessary to address the unsafe condition. This AD continues to require the actions in AD 2025-16-12 and requires repetitive replacement of each affected HPV clip. The FAA is issuing this AD to address the unsafe condition on these products.
