Airworthiness Directive · Amendment 39-14615 · Boeing Model 757 Airplanes
Boeing Model 757 Airplanes
Superseded. A later AD replaced this one: AD 2020-01-18. Comply with the one in force.
This AD applies to all Boeing Model 757-200, -200PF, -200CB, and -300 series airplanes, certificated in any category.
Note 1: This AD requires revisions to certain operator maintenance documents to incorporate new inspections for fatigue cracking of principal structural elements (PSEs). Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to incorporate the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (j) of this AD. The request should include a description of changes to the required inspections that will ensure the continued damage tolerance of the affected structure. The FAA has provided guidance for this determination in Advisory Circular (AC) 25-1529.
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 757 series airplanes. That AD currently requires revising the Airworthiness Limitations section of the maintenance manual (757 Airworthiness Limitations Instructions (ALI)) to incorporate certain inspections and compliance times to detect fatigue cracking of principal structural elements (PSEs). This new AD requires incorporating a new revision to the Airworthiness Limitations section of the Instructions of Continued Airworthiness to mandate certain repetitive inspections for fatigue cracking of PSEs, and adds airplanes to the applicability in the existing AD. This AD results from a new revision to the ALI. We are issuing this AD to ensure that fatigue cracking of various PSEs is detected and corrected; such fatigue cracking could adversely affect the structural integrity of these airplanes.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
For Model 757 series airplanes having line numbers 1 through 764 inclusive, and subject to the requirements of AD 2001-20-12: Within 3 years after November 20, 2001 (the effective date of AD 2001-20-12), revise Section 9 of the Boeing 757 Maintenance Planning Data (MPD) Document entitled “Airworthiness Limitations and Certification Maintenance Requirements (CMRs)” to incorporate Subsection B. of Boeing Document D622N001-9, Revision “May 1997” or Revision “November 1998.” Accomplishing the requirements in paragraph (h) of this AD ends the requirements in this paragraph.
Note 2: For the purposes of this AD, the terms PSEs as used in this AD, and Structural Significant Items (SSIs) as used in Section 9 of Boeing 757 MPD Document, are considered to be interchangeable.
Except as provided in paragraph (j) of this AD: After the actions required by paragraph (f) of this AD have been accomplished, no alternative inspections or inspection intervals shall be approved for the PSEs contained in Boeing Document D622N001-9, Revision “May 1997” or “November 1998.”
For all airplanes: Within 36 months after the effective date of this AD, revise Section 9, “Airworthiness Limitations and CMRs” of the Boeing 757 MPD Document to incorporate Subsection B. of Boeing Document D622N001-9, Revision “May 2003;” or Revision “June 2005,” as applicable. Accomplishing the requirements in this paragraph ends the requirements in paragraph (f) of this AD.
(i) Except as provided in paragraph (j) of this AD: After the actions required by paragraph (h) of this AD have been accomplished, no alternative inspections or inspection intervals shall be approved for the PSEs contained in Boeing 757 MPD Document D622N001-9, Revision “May 2003” or Revision “June 2005.”
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
