Airworthiness Directive · Amendment 39-19296 · Fuselage
The Boeing Company Airplanes
(1) This AD applies to The Boeing Company Model 767-200 and -300 series airplanes, as identified in Boeing Alert Requirements Bulletin 767-53A0278 RB, dated June 30, 2017, certificated in any category.
(2) Installation of Supplemental Type Certificate (STC) ST01920SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/59027F43B9A7486E86257B1D006591EE?OpenDocument&Highlight=st01920se) does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST01920SE 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.
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767-200 and -300 series airplanes. This AD was prompted by a report of two cracks at a certain frame inner chord. This AD requires a detailed inspection for any material review board (MRB) filler installed in the area from the frame web to the stub-beam fitting at certain stations to determine if the filler extends above the frame-to-stub-beam joint, and applicable on-condition actions. We are issuing this AD to address the unsafe condition on these products.
Except as required by paragraph (h) of this AD: At the applicable times specified in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 767-53A0278 RB, dated June 30, 2017, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 767-53A0278 RB, dated June 30, 2017.
Note 1 to paragraph (g) of this AD: Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 767-53A0278, dated June 30, 2017, which is referred to in Boeing Alert Requirements Bulletin 767-53A0278 RB, dated June 30, 2017.
(1) For purposes of determining compliance with the requirements of this AD: Where Boeing Alert Requirements Bulletin 767-53A0278 RB, dated June 30, 2017, uses the phrase “the original issue date of Requirements Bulletin 767-53A0278 RB,” this AD requires using “the effective date of this AD.”
(2) Where Boeing Alert Requirements Bulletin 767-53A0278 RB, dated June 30, 2017, specifies contacting Boeing, this AD requires repair using a method approved in accordance with the procedures specified in paragraph (i) of this AD.
(3) For airplanes identified as Group 1, Configuration 1, in Boeing Alert Requirements Bulletin 767-53A0278 RB, dated June 30, 2017, that have been modified to a freighter configuration: The actions specified in Boeing Alert Requirements Bulletin 767-53A0278 RB, dated June 30, 2017, for Group 1, Configuration 2, must be done instead of the actions for Group 1, Configuration 1, except as required by paragraph (h)(2) of this AD.
(4) For airplanes identified as Group 2, Configuration 1, in Boeing Alert Requirements Bulletin 767-53A0278 RB, dated June 30, 2017, that have been modified to a freighter configuration: The actions specified in Boeing Alert Requirements Bulletin 767-53A0278 RB, dated June 30, 2017, for Group 2, Configuration 2, must be done instead of the actions for Group 2, Configuration 1, except as required by paragraph (h)(2) of this AD.
