The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for certain MHI RJ Aviation ULC airplanes due to potential interference from 5G wireless broadband operations affecting radio altimeters. This directive mandates the installation of a radio frequency bandpass filter to prevent altimeter anomalies that could lead to unsafe flight conditions, such as overheating issues in the aircraft's hydraulic system or wing structural deformation. The AD follows comments received on its proposal and makes necessary adjustments, including referencing updated service bulletins for compliance. This final rule will help ensure continued safe flight and landing of affected aircraft by requiring timely modifications.
Simple Explanation
The FAA wants to add a special part to some airplanes to make sure their equipment works right and keeps them safe when they're flying, especially since there are new super-fast internet signals that might confuse the airplane's tools.
