The Federal Aviation Administration (FAA) has proposed a new airworthiness directive for certain Airbus Canada Limited Partnership airplanes. This directive aims to address corrosion issues on parts of the rear fuselage caused by waste valve leaks, which could lead to major structural damage. The proposal includes mandatory inspections and repairs as per guidelines from Transport Canada. The FAA is open to comments on this proposal until April 12, 2021.
Simple Explanation
The airplane people found some rust on important parts of some airplanes where the bathroom pipes leaked. They want to check all the airplanes to make sure they're safe and fix any that have rust growing.
