Description
The FAA is superseding AD 2023-08-04 for certain Boeing Model 787 airplanes. The new AD requires inspections of clamshell couplings in lavatory and galley potable water systems for safety straps, and prohibits installation of affected parts. It addresses unsafe conditions related to missing or incorrectly installed couplings that could lead to water leaks affecting critical flight equipment. The AD retains previous requirements and adds inspections for certain airplanes, terminating the existing requirements. It is effective June 3, 2026.
