(d) Subject Air Transport Association (ATA) of America Code 31, Instruments. (e) Unsafe Condition This AD was prompted by reports of display electronic unit (DEU) software errors on airplanes with a selected instrument approach to a specific runway. The FAA is proposing this AD to address the potential for all six display units (DUs) to blank, which can prevent continued safe flight and landing. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Retained AFM Revision, with No Changes This paragraph restates the requirements of paragraph (g) of AD 2019-25-17, with no changes. Within 14 days after December 27, 2019 (the effective date of AD 2019-25-17), revise the Miscellaneous Limitations section of the existing airplane flight manual (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 Miscellaneous Limitations section of the existing AFM. Figure 1 to Paragraph (g)-AFM Revision ER23SE24.007 (h) Software Update Except as specified in paragraph (i) of this AD: At the applicable times specified in paragraph 1.E., "Compliance," of Boeing Alert Requirements Bulletin 737-31A1880 RB, Revision 1, dated September 16, 2020, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 737-31A1880 RB, Revision 1, dated September 16, 2020.
