Airworthiness Directive · Amendment 39-21290 · Wings
The Boeing Company Airplanes
Superseded. A later AD replaced this one: AD 2022-08-12. Comply with the one in force.
(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 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.
The FAA is superseding Airworthiness Directive (AD) 2018-16- 05, which applied to certain The Boeing Company Model 757 airplanes. AD 2018-16-05 required repetitive inspections for skin cracking and shim migration at the upper link drag fittings, diagonal brace cracking, and fastener looseness; and applicable on-condition actions. This AD retains the actions required by AD 2018-16-05, reduces the compliance times for certain inspections, and adds repetitive inspections at certain fastener hole locations and applicable on-condition actions. This AD was prompted by reports of bolt rotation in the engine drag fitting joint and fastener heads; an inspection of the fastener holes revealed that cracks were found in the skin. This AD was also prompted by a report of multiple cracks in the drag fitting at fastener holes found during an inspection required by AD 2018-16-05. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified by paragraph (h) of this AD: At the applicable times specified in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 757-57A0073 RB, Revision 1, dated August 1, 2019, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 757-57A0073 RB, Revision 1, dated August 1, 2019.
Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 757-57A0073, Revision 1, dated August 1, 2019, which is referred to in Boeing Alert Requirements Bulletin 757-57A0073 RB, Revision 1, dated August 1, 2019.
(1) Where Boeing Alert Requirements Bulletin 757-57A0073 RB, Revision 1, dated August 1, 2019, uses the phrase “the Revision 1 date of Requirements Bulletin 757-57A0073 RB,” this AD requires using “the effective date of this AD.”
(2) Where Boeing Alert Requirements Bulletin 757-57A0073 RB, Revision 1, dated August 1, 2019, specifies contacting Boeing for repair instructions: This AD requires doing the repair and applicable on-condition actions before further flight using a method approved in accordance with the procedures specified in paragraph (j) of this AD.
(3) Where Boeing Alert Requirements Bulletin 757-57A0073 RB, Revision 1, dated August 1, 2019, uses the phrase “the effective date of AD 2018-16-05,” this AD requires using “September 10, 2018 (the effective date of AD 2018-16-05).”
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.
