Airworthiness Directive · Amendment 39-19215 · Equipment/furnishings
The Boeing Company Airplanes
Superseded. A later AD replaced this one: AD 2023-08-02. Comply with the one in force.
This AD applies to The Boeing Company Model 787-8 and 787-9 airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin B787-81205-SB500008-00, Issue 001, dated December 7, 2016.
We are superseding Airworthiness Directive (AD) 2016-09-12, which applied to certain The Boeing Company Model 787-8 and 787-9 airplanes. AD 2016-09-12 required repetitive inspections of the bilge barriers located in the forward and aft cargo compartments for disengaged decompression panels, and reinstalling any disengaged panels. This AD retains the actions required by AD 2016-09-12 and requires replacing the existing decompression panels with new panels and straps, which terminates the repetitive inspections. This AD also removes airplanes from the applicability. This AD was prompted by a terminating modification developed to address the unsafe condition. We are issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of paragraph (g) of AD 2016-09-12, with revised service information and an added reference to terminating action: At the applicable time specified in paragraph (g)(1) or (g)(2) of this AD, do a general visual inspection of the bilge barriers located in the forward and aft cargo compartments for disengaged decompression panels, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin B787-81205-SB500009-00, Issue 001, dated November 16, 2015; or Issue 003, dated December 7, 2016. Repeat the inspection thereafter at the applicable times specified in paragraph 5. “Compliance,” of Boeing Alert Service Bulletin B787-81205-SB500009-00, Issue 001, dated November 16, 2015; or Issue 003, dated December 7, 2016; until the terminating modification required by paragraph (i) of this AD is done. As of the effective date of this AD, only Boeing Alert Service Bulletin B787-81205-SB500009-00, Issue 003, dated December 7, 2016, may be used.
(1) For Group 1 airplanes identified in Boeing Alert Service Bulletin B787-81205-SB500009-00, Issue 001, dated November 16, 2015; or Issue 003, dated December 7, 2016: Inspect within 30 days after May 23, 2016 (the effective date of AD 2016-09-12).
(2) For Group 2 airplanes identified in Boeing Alert Service Bulletin B787-81205-SB500009-00, Issue 001, dated November 16, 2015; or Issue 003, dated December 7, 2016: Inspect within 180 flight cycles or within 90 days after May 23, 2016 (the effective date of AD 2016-09-12), whichever occurs later.
This paragraph restates the requirements of paragraph (h) of AD 2016-09-12, with revised service information: If any disengaged decompression panel is found during any inspection required by paragraph (g) of this AD; before further flight, reinstall the panel, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin B787-81205-SB500009-00, Issue 001, dated November 16, 2015; or Issue 003, dated December 7, 2016, as applicable. As of the effective date of this AD, only Boeing Alert Service Bulletin B787-81205-SB500009-00, Issue 003, dated December 7, 2016, may be used.
Within 36 months after the effective date of this AD: Replace the existing decompression panels of the bilge barriers located in the forward and aft cargo compartments with new decompression panels and adjustable straps (zip ties), in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin B787-81205-SB500008-00, Issue 001, dated December 7, 2016; except as provided by paragraph (j) of this AD. Accomplishing this modification terminates the repetitive inspections required by paragraph (g) of this AD.
