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\n2020-05-25 The Boeing Company: Amendment 39-19875; Docket No. FAA- 2019-0438; Product Identifier 2019-NM-033-AD. \n\n(a) Effective Date \n\n\n\tThis AD is effective May 4, 2020. \n\n(b) Affected ADs \n\n\n\tNone. \n\n(c) Applicability \n\n\n\t(1) This AD applies to all The Boeing Company Model 757-200, - 200PF, -200CB, and -300 series airplanes, certificated in any category. \n\t(2) Installation of Supplemental Type Certificate (STC) ST01518SE does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST01518SE is installed, a ''change in product'' alternative method of compliance (AMOC) approval request is not necessary to comply with the requirements of 14 CFR 39.17. \n\n(d) Subject \n\n\n\tAir Transport Association (ATA) of America Code 53, Fuselage. \n\n(e) Unsafe Condition \n\n\n\tThis AD was prompted by a report that during a maintenance check an operator discovered cracking of the aft cargo compartment frames in the station 1460 frame web and inner chord between certain stringers. The FAA is issuing this AD to address cracking at the frame web and inner chord; such cracks could propagate until they cause a severed frame, which could result in additional undetected cracking in adjacent fuselage frames, and could ultimately result in reduced structural integrity of the aft cargo frames and consequent rapid decompression of the airplane. \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\t(1) Except as specified by paragraphs (g)(2) and (h) of this AD: At the applicable times specified in the ''Compliance'' paragraph of Boeing Alert Requirements Bulletin 757-53A0113 RB, dated February 22, 2019, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 757-53A0113 RB, dated February 22, 2019. \n\t(2) For airplanes that have been converted from a passenger to freighter configuration using VT Mobile Aerospace Engineering Inc. (VT MAE Inc.) STC ST03562AT: Except as specified by paragraph (h) of this AD, at the times specified for Groups 3 and 5 airplanes, as applicable, in the ''Compliance'' paragraph of Boeing Alert Requirements Bulletin 757-53A0113 RB, dated February 22, 2019, do all \n\n((Page 17487)) \n\napplicable actions for Groups 2, 7, and 10 airplanes as identified in, and in accordance with the Accomplishment Instructions of Boeing Alert Requirements Bulletin 757-53A0113 RB, dated February 22, 2019.Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 757-53A0113, dated February 22, 2019, which is referred to in Boeing Alert Requirements Bulletin 757-53A0113 RB, dated February 22, 2019. \n\n(h) Exceptions To Service Information Specifications \n\n\n\t(1) Where Boeing Alert Requirements Bulletin 757-53A0113 RB, dated February 22, 2019, uses the phrase ''the original issue date of Requirements Bulletin 757-53A0113 RB,'' this AD requires using ''the effective date of this AD,'' except where Boeing Alert Requirements Bulletin 757-53A0113 RB, dated February 22, 2019, uses the phrase ''the original issue date of Requirements Bulletin 757- 53A0113 RB'' in a note or flag note. \n\t(2) Where Boeing Alert Requirements Bulletin 757-53A0113 RB, dated February 22, 2019, specifies contacting Boeing for repair instructions or for alternative inspections: This AD requires doing the repair, or doing the alternative inspections and applicable on- condition actions before further flight using a method approved in accordance with the procedures specified in paragraph (i) of this AD. \n\n(i) 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 local Flight Standards District 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 (j)(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, 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(j) Related Information \n\n\n\t(1) For more information about this AD, contact Peter Jarzomb, Aerospace Engineer, Airframe Section, FAA, Los Angeles ACO Branch, 3960 Paramount Boulevard, Lakewood, CA 90712-4137; phone: 562-627- 5234; 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 (k)(3) and (4) of this AD. \n\n(k) 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 757-53A0113 RB, dated February 22, 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.
