Boeing 787 lavatory leaks will now require part replacement, not just inspections

US aviation regulators are proposing a rule that will require airlines to replace a specific part in Boeing 787 lavatories, rather than just repeatedly inspecting them for leaks. This means airlines will have to install a new faucet control module to fix the problem permanently.

Airlines have been dealing with these lavatory leaks by constantly checking for them. This proposed rule forces a permanent fix, which means less maintenance hassle for airlines and fewer potential water damage issues for the planes. It shifts the burden from ongoing inspection costs to a one-time replacement cost.
