Unsafe condition
This AD was prompted by reports of undetected water leaks from the faucet control module (FCM) migrating below the passenger floor in multiple lavatory locations during flight, and into the electronic equipment bay(s). The FAA is issuing this AD to address undetected water leaks, which could damage flight critical equipment. The unsafe condition, if not addressed, could result in loss of multiple line replaceable units and subsequent loss of continued safe flight and landing.
Affected ADs
This AD replaces AD 2024-01-01, Amendment 39-22652 (89 FR 6422, February 1, 2024) (AD 2024-01-01).
