Airworthiness Directive · Amendment 39-23048 · Communications
Airbus SAS Airplanes
Superseded. A later AD replaced this one: AD 2026-14-05. Comply with the one in force.
This AD applies to the Airbus SAS Model airplanes identified in paragraphs (c)(1) through (3) of this AD, certificated in any category, having Airbus modification 162344 or 168460, except for airplanes having Airbus modification 165670 installed in production.
(1) Model A319-151N, -153N, -171N, and -173N airplanes.
(2) Model A320-251N, -252N, -253N, -271N, -272N, and -273N airplanes.
(3) Model A321-251N, -251NX, -252N, -252NX, -253N, -253NX, -253NY, -271N, -271NX, -272N, and -272NX airplanes.
The FAA is adopting a new airworthiness directive (AD) for 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. This AD was prompted by reports of lost synchronization between radio management panels (RMPs). This AD requires revising the existing airplane flight manual (AFM) by providing instructions to address dual loss of RMP data synchronization. The FAA is issuing this AD to address the unsafe condition on these products.
Within 7 days after the effective date of this AD, revise the Emergency Procedures section of the existing AFM to include the information in figure 1 or figure 2 to paragraph (g) of this AD, as applicable. This may be done by inserting a copy of figure 1 or figure 2 to paragraph (g) of this AD, as applicable, into the existing AFM. Using a different document with information identical to that contained in figure 1 or figure 2 to paragraph (g) of this AD, as applicable, is acceptable for compliance with the requirements of this paragraph.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
