The Federal Aviation Administration (FAA) has proposed a new rule to replace a previous Airworthiness Directive (AD 2019-22-07) for certain MHI RJ Aviation ULC airplane models, including various Regional Jet series. The initial directive required updates to the airplane flight manual to address a safety issue with the Automatic Flight Control System (AFCS) that could result in reduced control of the airplane during certain flight modes. However, additional unsafe conditions have been identified, prompting the FAA to propose further revisions to the flight manuals and expand the applicability of the AD to include additional airplane models. The FAA invites comments on this proposal by April 12, 2021, to address these safety concerns effectively.
Simple Explanation
The FAA wants to change a safety rule for some airplanes to make sure pilots have better instructions to keep the planes safe during flights. They also want to include more types of airplanes in this updated rule and are asking for feedback to make sure everything is covered.
