The FAA proposes to supersede Airworthiness Directive (AD) 2023-08-04, which applies to certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. AD 2023-08-04 requires 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. Since the FAA issued AD 2023-08- 04, Boeing has discovered that some couplings did not have the required safety strap and has developed a design solution that replaces the couplings with couplings that have safety straps to address the unsafe condition. This proposed AD would retain the requirements of AD 2023- 08-04 and require 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. The AD would also prohibit the installation of affected parts at inspection locations and remove Model 787-10 airplanes from the applicability. The FAA is proposing this AD to address the unsafe condition on these products.
