The FAA has issued a final rule requiring inspections for certain Airbus Canada Model BD-500-1A10 and BD-500-1A11 airplanes due to insufficient clearance between fire extinguishing system lines and fasteners, which could lead to a failure in the fire extinguishing system. This rule, effective May 2, 2025, mandates inspections and corrective actions to prevent a possible unsafe condition caused by the fouling of fire extinguishing lines, as outlined in an airworthiness directive from Transport Canada. The FAA addressed comments received during rulemaking and clarified part number corrections and compliance timelines.
Simple Explanation
The FAA has made a new rule saying some airplanes need checking because there might be a problem with how the fire safety parts are set up, which could be dangerous, and they want to make sure everything is safe.
