## Summary

We propose to supersede Airworthiness Directive (AD) 2016-09- 12, which applies to certain The Boeing Company Model 787-8 and 787-9 airplanes. AD 2016-09-12 currently requires repetitive inspections of the bilge barriers located in the forward and aft cargo compartments for disengaged decompression panels, and reinstalling any disengaged panels. Since we issued AD 2016-09-12, a terminating modification has been developed to address the unsafe condition. This proposed AD would retain the actions required by AD 2016-09-12 and require replacing the existing decompression panels with new panels and straps, which would terminate the repetitive inspections. This proposed AD also removes airplanes from the effectivity. We are proposing this AD to address the unsafe condition on these products.
