The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. This action comes after a design review found that the software meant to protect against large leaks in the engine bleed duct was not fully functional, which could lead to dual engine failure. The directive requires airlines to update their airplane flight manuals with new procedures for manual isolation of certain engine functions in the event of a bleed duct leak. The purpose of this rule is to improve safety and prevent potential accidents.
Simple Explanation
The government wants to make sure certain airplanes don't have a problem where big leaks can make the engines fail. So, they decided the pilots need new instructions in their books for how to handle these leaks, helping keep everybody safe in the sky!
