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\n2019-16-13 The Boeing Company: Amendment 39-19716; Docket No. FAA- 2018-0495; Product Identifier 2017-NM-089-AD. \n\n(a) Effective Date \n\n\n\tThis AD is effective November 14, 2019. \n\n(b) Affected ADs \n\n\n\tThis AD affects AD 2002-16-15, Amendment 39-12854 (67 FR 54333, August 22, 2002) (''AD 2002-16-15'') and AD 2014-11-01, Amendment 39-17851 (79 FR 31851, June 3, 2014) (''AD 2014-11-01''). \n\n(c) Applicability \n\n\n\tThis AD applies to The Boeing Company Model 777-200 and -300 series airplanes, certificated in any category, as identified in Boeing Special Attention Service Bulletin 777-28-0082, Revision 2, dated May 31, 2019. \n\n((Page 54489)) \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 unreliable performance of the water and fuel scavenge system; failure of the fuel scavenge function can cause trapped fuel, resulting in unavailable fuel reserves. We are issuing this AD to address loss of capability to scavenge fuel in the center fuel tank, which could lead to fuel exhaustion and subsequent power loss of all engines. \n\n(f) Compliance \n\n\n\tComply with this AD within the compliance times specified, unless already done. \n\n(g) Revision to Operating Limitations \n\n\n\tWithin 36 months after the effective date of this AD: Revise the operating limitations in the documents specified in paragraphs (g)(1) and (2) of this AD to include the text in figure 1 to paragraph (g) of this AD. \n\t(1) ''Fuel System--Loading'' section of the ''Certificate Limitations'' section of the FAA-approved Boeing Model 777 Airplane Flight Manual. \n\t(2) ''Loading Limitations'' section of the ''Fuel Loading Procedures'' section of the ''Fuel Management'' section of the FAA- approved Boeing Model 777 Weight and Balance Control and Loading Manual.

In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the manager of the ACO branch, send it to the attention of the person identified in paragraph (k)(1) of this AD. Information may be emailed to: [email protected]. \n\t(2) Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office. \n\t(3) An AMOC that provides an acceptable level of safety may be used for any repair, modification, or alteration required by this AD if it is approved by The Boeing Company Organization Designation Authorization (ODA) that has been authorized by the Manager, Seattle ACO, FAA, to make those findings. To be approved, the repair method, modification deviation, or alteration deviation must meet the certification basis of the airplane, and the approval must specifically refer to this AD. \n\t(4) For service information that contains steps that are labeled as RC, the provisions of paragraphs (j)(4)(i) and (ii) of this AD apply. \n\t(i) The steps labeled as RC, including substeps under an RC step and any figures identified in an RC step, must be done to comply with the AD. If a step or substep is labeled ''RC Exempt,'' then the RC requirement is removed from that step or substep. An AMOC is required for any deviations to RC steps, including substeps and identified figures. \n\t(ii) Steps not labeled as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program without obtaining approval of an AMOC, provided the RC steps, including substeps and identified figures, can still be done as specified, and the airplane can be put back in an airworthy condition. \n\t(5) For airplanes in Groups 1 through 4, and 7 through 14, as defined in Boeing Special Attention Service Bulletin 777-28-0082, Revision 1, dated May 1, 2017: Accomplishment of the engine fuel feed system modification specified in paragraph (h) of this AD is acceptable for compliance with the routing requirements of fuel quantity indicating system wire bundle W8011 in the left side of the body center fuel tank specified in paragraph (a)(2) of AD 2002-16- 15, provided all provisions of AD 2002-16-15 that are not specifically described in this paragraph are complied with accordingly. \n\t(6) Accomplishment of the ELMS1 OPS software installation specified in paragraph (h) of this AD is acceptable for compliance with the ELMS OPS software requirement specified in paragraph (h)(5) of AD 2014-11-01, provided all provisions of AD 2014-11-01 that are not specifically described in this paragraph are complied with accordingly. \n\n(k) Related Information \n\n\n\t(1) For more information about this AD, contact Kevin Nguyen, Aerospace Engineer, Propulsion Section, FAA, Seattle ACO Branch, 2200 South 216th St., Des Moines, WA 98198; phone and fax: 206-231- 3555; email: [email protected]. \n\t(2) Service information identified in this AD that is not incorporated by reference is available at the addresses specified in paragraphs (l)(3) and (4) of this AD. \n\n(l) Material Incorporated by Reference \n\n\n\t(1) The Director of the Federal Register approved the incorporation by reference (IBR) of the service information listed in this paragraph under 5 U.S.C. 552(a) and 1 CFR part 51. \n\t(2) You must use this service information as applicable to do the actions required by this AD, unless the AD specifies otherwise. \n\t(i) Boeing Special Attention Service Bulletin 777-28-0082, Revision 2, dated May 31, 2019. \n\t(ii) (Reserved) \n\t(3) For service information identified in this AD, contact Boeing Commercial Airplanes, Attention: Contractual & Data Services (C&DS), 2600 Westminster Blvd., MC 110-SK57, Seal Beach, CA 90740- 5600; telephone 562-797-1717; internet https://www.myboeingfleet.com. \n\t(4) You may view this service information at the FAA, Transport Standards Branch, 2200 South 216th St., Des Moines, WA.
