    Type:Rule
    Citation:90 FR 10851
    Reading Time:about 8 minutes

    The Federal Aviation Administration (FAA) has issued a new rule for all ATR-GIE Avions de Transport RĂ©gional Model ATR72 airplanes due to reports of a main landing gear hinge pin failure. This rule mandates replacing faulty parts and bars the installation of defective ones, following a directive from the European Union Aviation Safety Agency. The AD aims to prevent potential structural failures that could endanger airplanes and their passengers. It affects 41 US-registered planes and takes effect on April 4, 2025.

    Simple Explanation

    The FAA made new rules to fix a part on some big airplanes because a piece on the plane's wheels might break. This stops it from breaking in the future and keeps everyone safe.

    The FAA has issued a new airworthiness directive (AD) for Boeing 727 airplanes due to risks caused by excessive sealant on wing parts, which might hide cracks during inspections. This rule mandates changes to maintenance or inspection programs to ensure the required damage tolerance rating and repetitive inspections of certain wing parts to detect potential issues. Effective March 31, 2021, this AD aims to prevent possible structural failures that could lead to loss of control of the aircraft. The directive includes compliance procedures, costs, and the regulatory rationale behind these safety measures.

    Simple Explanation

    The FAA made a new safety rule for Boeing 727 airplanes because too much glue on the wings might hide cracks. They want regular check-ups to keep the airplane safe and flying properly.

    Reading Time:about 11 minutes

    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.
