  • 2025-02374 — Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
    Type:Rule
    Citation:90 FR 9212
    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.

  • 2025-03441 — Airworthiness Directives; Pratt & Whitney Engines
    Type:Rule
    Citation:90 FR 11099
    Reading Time:about 17 minutes

    The Federal Aviation Administration (FAA) has issued a new rule concerning certain models of Pratt & Whitney engines. Prompted by an incident where a specific engine part failed leading to an aborted takeoff, this rule requires inspections and possible replacements of the high-pressure compressor 7th-stage axial rotors on these engines to ensure safety. Inspections must be conducted whenever the rotor is exposed during engine maintenance, and parts showing signs of cracks must be replaced. This rule applies to several engine models and comes into effect on April 8, 2025, with the intention to prevent similar unsafe incidents in the future.

    Simple Explanation

    The FAA made a new rule to check and fix a part in certain Pratt & Whitney engines because one part broke and stopped a plane from taking off. This rule helps keep planes safe by looking for cracks in a specific engine part and fixing it before it causes problems.
