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\n2019-19-10 The Boeing Company: Amendment 39-19746; Docket No. FAA- 2017-1024; Product Identifier 2017-NM-065-AD. \n\n(a) Effective Date \n\n\n\tThis AD is effective January 16, 2020. \n\n(b) Affected ADs \n\n\n\tThis AD affects AD 88-21-03 R1, Amendment 39-6077 (53 FR 46605, November 18, 1988) (''AD 88-21-03 R1''). \n\n(c) Applicability \n\n\n\tThis AD applies to all The Boeing Company airplanes, certificated in any category, identified in paragraphs (c)(1) through (5) of this AD. \n\t(1) Model 737-300, -400, -500, -600, -700, -700C, -800, -900, and -900ER series airplanes. \n\t(2) Model 757-200, -200PF, -200CB, and -300 series airplanes. \n\t(3) Model 767-200, -300, -300F, and -400ER series airplanes. \n\t(4) Model 777-200, -200LR, -300, -300ER, and -777F series airplanes. \n\t(5) Model 787-8 and 787-9 airplanes. \n\n(d) Subject \n\n\n\tAir Transport Association (ATA) of America Code 28; Fuel. \n\n(e) Unsafe Condition \n\n\n\tThis AD was prompted by reports of fuel crossfeed valves failing to open when activated during flight. The FAA is issuing this AD to prevent an airplane from being dispatched on an extended operations (ETOPS) flight with a single fuel crossfeed valve (due to design or due to minimum equipment list (MEL) dispatch of a dual crossfeed valve equipped airplane with one crossfeed valve inoperative) that cannot be opened or a fuel balancing system that cannot properly operate when activated. This condition could cause the fuel in the main tank associated with a failed engine to be unavailable to the remaining operative engine, potentially resulting in a forced off airport landing due to exhaustion of the remaining usable fuel and consequent loss of all engine thrust. \n\n(f) Compliance \n\n\n\tComply with this AD within the compliance times specified, unless already done. \n\n(g) AFM Revisions for Model 737 Airplanes Equipped With a Single Fuel Crossfeed Valve \n\n\n\tFor airplanes identified in paragraph (c)(1) of this AD: Within 120 days after the effective date of this AD, do the actions specified in paragraphs (g)(1) and (2) of this AD. \n\t(1) Revise the ''Extended Range Operations'' subsection of the ''Fuel System Limitations'' section of the Section 1 Certificate Limitations of the existing airplane flight manual (AFM) by incorporating the information specified in figure 1 to paragraph (g)(1) of this AD. This may be done by inserting a copy of this AD into the existing AFM. When a statement identical to that in figure 1 to paragraph (g)(1) of this AD has been included in the ''Extended Range Operations'' subsection of the ''Fuel System Limitations'' section of the Section 1 Certificate Limitations of the general revisions of the existing AFM, the general revisions may be inserted into the existing AFM, and the copy of this AD may be removed from the existing AFM. \n\n((Page 67845)) \n\n(GRAPHIC) (TIFF OMITTED) TR12DE19.000 \n\n\n\t(2) Revise the ''Extended Range Operations'' section of the Section 3 Normal Procedures of the existing AFM by incorporating the information specified in figure 2 to paragraph (g)(2) of this AD. This may be done by inserting a copy of this AD into the existing AFM. When a statement identical to that in figure 2 to paragraph (g)(2) of this AD has been included in the ''Extended Range Operations'' section of Section 3 Normal Procedures of the existing AFM, the general revisions may be inserted into the existing AFM, and the copy of this AD may be removed from the existing AFM. (GRAPHIC) (TIFF OMITTED) TR12DE19.001 \n\n(h) AFM Revisions for Model 757 Airplanes Equipped With a Single Fuel Crossfeed Valve \n\n\n\tFor airplanes identified in paragraph (c)(2) of this AD having line numbers 1 through 518 inclusive, on which the actions specified in Boeing Service Bulletin 757-28-0029 (second fuel crossfeed valve installation) have not been done: Within 120 days after the effective date of this AD, do the actions specified in paragraphs (h)(1) and (2) of this AD. For Model 757 airplanes identified in this paragraph, if the actions specified in Boeing Service Bulletin 757-28-0029 have been done, the actions specified in this paragraph are no longer required for that airplane and the actions specified in paragraph (j) of this AD must be done before further flight after the actions specified in Boeing Service Bulletin 757-28-0029 have been performed. \n\t(1) Revise the ''Extended Range Operations'' section of the Section 1 Certificate Limitations of the existing AFM by incorporating the information specified in figure 3 to paragraph (h)(1). This may be done by inserting a copy of this AD into the existing AFM. When a statement identical to that in figure 3 to paragraph (h)(1) of this AD has been included in the ''Extended Range Operations'' section of the Section 1 Certificate Limitations of the general revisions of the existing AFM, the general revisions may be inserted into the existing AFM, and the copy of this AD may be removed from the existing AFM. \n\n((Page 67846)) \n\n(GRAPHIC) (TIFF OMITTED) TR12DE19.002 \n\n\n\t(2) Revise the ''Extended Range Operations'' section of Section 3 Normal Procedures of the existing AFM by incorporating the information specified in figure 4 to paragraph (h)(2) of this AD.
