## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2024-01-01, which applies to certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. AD 2024-01-01 requires repetitive general visual inspections (GVIs) of the area under all lavatory washbasins for evidence of intermittent and active leaks at the faucet control module (FCM) and applicable on-condition actions. The FAA has determined that the affected FCMs must be replaced with an improved design FCM to address the unsafe condition. This proposed AD would continue to require the actions of AD 2024-01-01 and would require replacing the FCM as terminating action for the repetitive GVIs, performing a leak test, installing moisture management devices, and performing applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
