Airworthiness Directives; The Boeing Company Airplanes

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.
