The Federal Aviation Administration (FAA) is proposing a new airworthiness directive (AD) for specific Boeing 737-9 airplanes due to safety concerns about missing sealant on parts of the wings. This missing sealant could lead to a fuel leak and potentially a major ground fire if not addressed. The directive would require inspections and the application of sealant where necessary. Comments on this proposal are open until March 8, 2021, and detailed instructions for submitting feedback can be found at the federal regulations website.
Simple Explanation
The FAA wants to make sure some Boeing airplanes are safe by fixing missing glue on parts of the wings, which could cause dangerous fuel leaks. They want people to check the wings and add more glue if it's missing.
