AD 2020-01-18

This AD is effective March 5, 2020.

This AD replaces AD 2006-11-11, Amendment 39-14615 (71 FR 30278, May 26, 2006) (“AD 2006-11-11”).

(1) This AD applies to all The Boeing Company Model 757-200, -200PF, -200CB, and -300 series airplanes, certificated in any category.

(2) Installation of Supplemental Type Certificate (STC) ST01518SE affects 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 necessary to comply with the requirements of 14 CFR 39.17.

Air Transport Association (ATA) of America Code 28, Fuel; 53, Fuselage; 57, Wings.

This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address fatigue cracking of various principal structural elements (PSEs); such fatigue cracking could adversely affect the structural integrity of these airplanes.

Comply with this AD within the compliance times specified, unless already done.

This paragraph restates the requirements of paragraph (h) of AD 2006-11-11, with no changes. Within 36 months after June 30, 2006 (the effective date of AD 2006-11-11), revise Section 9, “Airworthiness Limitations and CMRs” of the Boeing 757 Maintenance Planning Data (MPD) Document to incorporate Subsection B. of Boeing Document D622N001-9, Revision “May 2003;” or Revision “June 2005;” as applicable.

(1) Except for airplanes identified in paragraph (h)(2) of this AD: Within 18 months after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Subsection B., “Airworthiness Limitations—Structural Inspections,” of Boeing 757 Maintenance Planning Data (MPD) Document, Section 9, Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs), D622N001-9, Revision October 2018. The initial compliance time for doing the new or updated tasks is at the time specified in Subsection B., “Airworthiness Limitations—Structural Inspections,” of Boeing 757 Maintenance Planning Data (MPD) Document, Section 9, Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs), D622N001-9, Revision October 2018, or within 18 months after the effective date of this AD, whichever occurs later. The compliance time for doing the unchanged tasks is at the time specified in Subsection B., “Airworthiness Limitations—Structural Inspections,” of Boeing 757 Maintenance Planning Data (MPD) Document, Section 9, Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs), D622N001-9, Revision October 2018.

(2) For airplanes with STC ST01518SE installed: Within 18 months after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate a supplemental program to address the effect of STC ST01518SE, in accordance with the procedures specified in paragraph (l) of this AD.

Except as required by paragraph (h) of this AD: After the existing maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions ( e.g., inspections), intervals, or CDCCLs may be used unless the actions, intervals, and CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (l) of this AD.

After the existing maintenance or inspection program has been revised as required by paragraph (h) of this AD, no alternative actions ( e.g., inspections), intervals, or CDCCLs may be used unless the actions, intervals, and CDCCLs are approved as an AMOC in accordance with the procedures specified in paragraph (l) of this AD.

Accomplishing the revision required by paragraph (h) of this AD terminates the revision required by paragraph (g) of this AD.

(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 (m) of this AD. Information may be emailed to: 9-ANM-LAACO-AMOC-Requests@faa.gov.

(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.

(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.

(4) AMOCs approved previously for AD 2001-20-12, Amendment 39-12460 (66 FR 52492, October 16, 2001), and AD 2006-11-11, are approved as AMOCs for the corresponding provisions of this AD.
