Airworthiness Directive · Amendment 39-18510 · Equipment/furnishings
The Boeing Company Airplanes
Superseded. A later AD replaced this one: AD 2018-05-06. 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-SB500009-00, Issue 001, dated November 16, 2015.
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 and 787-9 airplanes. This AD requires 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 was prompted by several reports of disengaged decompression panels found on in-service airplanes. We are issuing this AD to detect and correct disengaged decompression panels from the bilge barriers located in the forward and aft cargo compartments. In the event of a cargo compartment fire, this condition would provide a path for smoke and Halon to enter the flight compartment and passenger cabin, which could result in the inability to contain and extinguish a fire.
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. 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.
(1) For Group 1 airplanes identified in Boeing Alert Service Bulletin B787-81205-SB500009-00, Issue 001, dated November 16, 2015: Inspect within 30 days after the effective date of this AD.
(2) For Group 2 airplanes identified in Boeing Alert Service Bulletin B787-81205-SB500009-00, Issue 001, dated November 16, 2015: Inspect within 180 flight cycles or within 90 days after the effective date of this AD, whichever occurs later.
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.
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.
