Adoption of the Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n\n\nSec. 39.13 (Amended) \n\n0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): \n\n2019-25-17 The Boeing Company: Amendment 39-21016; Docket No. FAA- 2019-0992; Product Identifier 2019-NM-197-AD. \n\n(a) Effective Date \n\n\n\tThis AD is effective December 27, 2019. \n\n(b) Affected ADs \n\n\n\tNone. \n\n(c) Applicability \n\n\n\tThis AD applies to all The Boeing Company Model 737-600, -700, - 700C, -800, -900, and -900ER series airplanes, certificated in any category. \n\n\n\tNote 1 to paragraph (c): The scope of the AD requirements is limited to operation at the seven runways identified in figure 1 to paragraph (g) of this AD. \n\n(d) Subject \n\n\n\tAir Transport Association (ATA) of America Code 31, Indicating/ recording system. \n\n(e) Unsafe Condition \n\n\n\tThis AD was prompted by reports of display unit (DU) software errors on airplanes with a selected instrument approach to a specific runway. The FAA is issuing this AD to address the potential for all six DUs to blank, which can prevent continued safe flight and landing. \n\n(f) Compliance \n\n\n\tComply with this AD within the compliance times specified, unless already done. \n\n(g) AFM Revision \n\n\n\tWithin 14 days after the effective date of this AD, 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. \n\n((Page 71306)) \n\n(GRAPHIC) (TIFF OMITTED) TR27DE19.000 \n\n(h) Alternative Methods of Compliance (AMOCs)(1) The Manager, Seattle ACO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
