Airworthiness Directive coverage
FAA / EASA public regulatory data
- FAAAD 2026-09-01effective Jun 3, 2026Prohibition
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.
Directives citing this part number in the FAA / EASA regulatory corpus we have processed — not a complete historical AD list. An AD is a compliance requirement that drives scheduled work (inspections, replacements, modifications) on the fleets that carry the part; a directive naming this PN as the replacement part is install demand, not an action against it — and none of this is a prediction that the part will fail.
