The Federal Aviation Administration (FAA) has issued a final rule requiring new safety inspections for MHI RJ Aviation ULC Model CL-600-2B19 airplanes, due to ultrasonic inspections potentially missing cracks in certain areas. The rule, effective March 17, 2025, mandates repeated ultrasonic inspections and repairs for cracking in specific structural parts. These measures aim to prevent structural failures stemming from undetected cracks. The rule incorporates standards from a related Transport Canada directive and requires using updated inspection procedures.
Simple Explanation
The FAA says there are some airplanes that need special checks to make sure they don't have cracks that could lead to bigger problems, like pieces breaking. They want these checks done regularly and in a specific way to keep everything safe.
