The FAA is issuing this AD to address loss of communications means (RMP data synchronization and very high frequency (VHF) communications) on the digital radio and audio integrating management system (DRAIMS). This condition, if not corrected, could result in total loss of radio communications, including transponder functionality and standby navigation. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Airplane Flight Manual (AFM) Revision 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.
