## Abstract

The FAA is superseding Airworthiness Directive (AD) 2021-02- 19, which applied to certain The Boeing Company Model 787-8, -9, and - 10 airplanes. AD 2021-02-19 required repetitive general visual inspections for disengaged or damaged decompression panels of the bilge barriers located in the forward and aft cargo compartments, reinstallation of disengaged but undamaged panels, and replacement of damaged panels. This AD was prompted by reports of multiple incidents of torn decompression panels found in the bilge area, and the determination that additional airplanes are subject to the unsafe condition. This AD retains the requirements of AD 2021-02-19 and revises the applicability by including additional airplanes. The FAA is issuing this AD to address the unsafe condition on these products.
