## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2025-09-07, which applies to certain Airbus SAS Model A330-243, -243F, -841, and -941 airplanes. AD 2025-09-07 requires revising the existing airplane flight manual (AFM) by providing instructions to address dual loss of radio management panel (RMP) data synchronization, and the existing minimum equipment list (MEL) by removing relief for an inoperative RMP 3. Since the FAA issued AD 2025-09-07, a modification that addresses the unsafe condition has been developed. This proposed AD would continue to require the actions specified in AD 2025-09-07 and would require modifying the airplane. This proposed AD also reduces the applicability. This proposed AD would also prohibit the installation of affected parts under certain conditions. The FAA is proposing this AD to address the unsafe condition on these products.
