Airworthiness Directive · Amendment 39-22251 · Fire protection
The Boeing Company Airplanes
This AD applies to all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD was prompted by a report indicating that foreign object debris (FOD) could have been introduced during rework of certain engine fire shutoff switches (EFSSs). This AD requires determining the serial number of the left and right EFSS and replacing affected parts. This AD also limits the installation of affected parts under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
For airplanes with an original airworthiness certificate or original export certificate of airworthiness issued on or before the effective date of this AD: Except as specified by paragraph (h) of this AD, at the applicable time specified in the “Compliance” paragraph of Boeing Alert Requirements Bulletin B787-81205-SB260010-00 RB, Issue 001, dated May 2, 2022, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin B787-81205-SB260010-00 RB, Issue 001, dated May 2, 2022.
Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin B787-81205-SB260010-00, Issue 001, dated May 2, 2022, which is referred to in Boeing Alert Requirements Bulletin B787-81205-SB260010-00 RB, Issue 001, dated May 2, 2022.
Where the Compliance Time column of the table in the “Compliance” paragraph of Boeing Alert Requirements Bulletin B787-81205-SB260010-00 RB, Issue 001, dated May 2, 2022, uses the phrase “the Issue 001 date of Requirements Bulletin B787-81205-SB260010-00 RB,” this AD requires using “the effective date of this AD.”
For airplanes with an original airworthiness certificate or original export certificate of airworthiness issued after the effective date of this AD: As of the effective date of this AD, no person may install a left EFSS P/N 417000-104 or a right EFSS P/N 417000-105, having a serial number specified in Boeing Alert Requirements Bulletin B787-81205-SB260010-00 RB, Issue 001, dated May 2, 2022, unless that EFSS is marked with “Inspection Record SB D533-1X-003.”
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.
