The FAA is superseding Airworthiness Directive (AD) 2025-11- 02, which applied to certain Airbus SAS Model A319-151N, -153N, -171N, and -173N airplanes; A320-251N, -252N, -253N, -271N, -272N, and -273N airplanes; A321-251N, -251NX, -252N, -252NX, -253N, -253NX, -253NY, - 271N, -271NX, -272N, and -272NX airplanes. AD 2025-11-02 required revising the existing airplane flight manual (AFM) by providing instructions to address dual loss of radio management panel (RMP) data synchronization. Since the FAA issued AD 2025-11-02, a software modification for the digital radio and audio integrating management system (DRAIMS) has been developed to address the unsafe condition. This AD continues to require the actions in AD 2025-11-02, requires modification of the DRAIMS, and adds Model A321-271NY airplanes to the applicability. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
