summary: 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.
