Boeing 747s need new shields to stop water leaks from shorting out electronics
What happened
US aviation regulators want Boeing to fix a problem on its 747 airplanes. Water leaks from the potable water system have been shorting out critical electronics.
Why it matters
This is a small, specific fix for a known problem. It means airlines will have to spend money to install new shields and conduits on their 747s. The goal is to prevent water from reaching the electronics that control the engines and alert the crew.
The signal
Watch for the final rule to be published and how quickly airlines comply with the new requirements.
