AD FAA-2016-6149

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.
