Airworthiness Directive · Amendment 39-23028 · Communications
Airbus SAS Airplanes
This AD applies to Airbus SAS Model A330-243, -243F, -841, and -941 airplanes, certificated in any category, with the digital radio management panel (RMP) function installed by Airbus modification 207423.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-243, -243F, -841, and -941 airplanes. This AD was prompted by reports of loss of data synchronization between radio management panels (RMPs) and the audio management unit (AMU). This AD requires revising the existing airplane flight manual (AFM) by providing instructions to address dual loss of RMP data synchronization, and the existing minimum equipment list (MEL) by removing relief for an inoperative RMP 3. 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 to paragraph (g) of this AD. This may be done by inserting a copy of figure 1 to paragraph (g) of this AD into the existing AFM. Using a different document with information identical to that contained in figure 1 to paragraph (g) of this AD is acceptable for compliance with the requirements of this paragraph.
Before further flight after accomplishing the requirements of paragraph (g) of this AD, revise the existing FAA-approved MEL to prohibit airplane dispatch (operation) with an inoperative RMP 3 under the MEL item equivalent to FAA master minimum equipment list (MMEL) 23-81-01.
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.
