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: 0 a. Removing Airworthiness Directive (AD) 2017-26-10, Amendment 39-19141 (82 FR 61675, December 29, 2017); and 0 b. Adding the following new AD: \n\n2021-05-11 The Boeing Company: Amendment 39-21454 ; Docket No. FAA- 2020-0903; Project Identifier AD-2020-00957-T. \n\n(a) Effective Date \n\n\n\tThis airworthiness directive (AD) is effective April 19, 2021. \n\n(b) Affected ADs \n\n\n\tThis AD replaces AD 2017-26-10, Amendment 39-19141 (82 FR 61675, December 29, 2017). \n\n(c) Applicability \n\n\n\tThis AD applies to The Boeing Company Model 757-200, -200PF, - 200CB, and -300 series airplanes, certificated in any category, as identified in Boeing Alert Requirements Bulletin 757-27A0158 RB, dated July 9, 2020. \n\n(d) Subject \n\n\n\tAir Transport Association (ATA) of America Code 27, Flight controls. \n\n(e) Unsafe Condition \n\n\n\tThis AD was prompted by reports of unwanted lateral oscillations during landing operations, and the development of wiring changes for certain spoiler control modules (SCMs), which will improve the lateral handling qualities of the airplane during approach and landing. The FAA is issuing this AD to address unwanted lateral oscillations during landing operations, which could cause over- control of the airplane and subsequent lateral pilot induced oscillation, which could affect 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) Required Actions \n\n\n\tExcept as specified by paragraph (h) of this AD: At the applicable times specified in the ''Compliance'' paragraph of Boeing Alert Requirements Bulletin 757-27A0158 RB, dated July 9, 2020, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 757-27A0158 RB, dated July 9, 2020. \n\tNote 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 757-27A0158, dated July 9, 2020, which is referred to in Boeing Alert Requirements Bulletin 757-27A0158 RB, dated July 9, 2020. \n\n(h) Exceptions to Service Information Specifications \n\n\n\t(1) Where Boeing Alert Requirements Bulletin 757-27A0158 RB, dated July 9, 2020, uses the phrase ''the original issue date of the Requirements Bulletin 757-27A0158 RB,'' this AD requires using ''the effective date of this AD.'' \n\t(2) Where Boeing Alert Requirements Bulletin 757-27A0158 RB, dated July 9, 2020, specifies in figure 4 (sheet 3 of 3), step 2, to drill a quantity of six holes, this AD requires drilling two holes. \n\n(i) Minimum Equipment List (MEL) \n\n\n\tIn the event that the spoiler inhibit function (SIF) system as modified by this AD is inoperable, an airplane may be operated as specified in the operator's existing FAA-approved MEL, provided the operator's existing FAA-approved MEL includes provisions that address the modified SIF system. \n\n(j) Alternative Methods of Compliance (AMOCs) \n\n\n\t(1) The Manager, Los Angeles ACO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or responsible Flight Standards Office, as appropriate. If sending information directly to the manager of the certification office, 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 responsible Flight Standards 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, Los Angeles ACO Branch, 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\n((Page 14244)) \n\n\n\t(4) AMOCs approved previously for AD 2017-26-10 are approved as AMOCs for the corresponding provisions of this AD. \n\n(k) Related Information \n\n\n\t(1) For more information about this AD, contact Katherine Venegas, Aerospace Engineer, Cabin Safety and Environmental Systems Section, FAA, Los Angeles ACO Branch, 3960 Paramount Boulevard, Lakewood, CA 90712-4137; phone: 562-627-5353; fax: 562-627-5210; 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 Alert Requirements Bulletin 757-27A0158 RB, dated July 9, 2020. \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, Airworthiness Products Section, Operational Safety Branch, 2200 South 216th St., Des Moines, WA.
