ACTION: Final rule. SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2023-08-04, which applied to certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. AD 2023-08-04 required a detailed visual inspection of all door 1 and door 3 lavatory and galley potable water systems for any missing or incorrectly installed clamshell couplings, and applicable on-condition actions. This AD was prompted by discoveries by Boeing that some couplings did not have the required safety strap and that they have developed a design solution that replaces the couplings with couplings that have safety straps. This AD retains the requirements of AD 2023-08-04 and requires, for certain airplanes, a detailed inspection of all clamshell couplings for the presence and correct installation of safety straps at door 1 and door 3 lavatories and galleys with a potable water system and applicable on-condition actions, which would terminate the existing requirements. This AD also prohibits the installation of affected parts at inspection locations. The FAA is issuing this AD to address the unsafe condition on these products.
