  • 2025-06067 — Airworthiness Directives; Airbus Helicopters
    💰
    Type:Rule
    Citation:90 FR 15306
    Reading Time:about 15 minutes

    The Federal Aviation Administration (FAA) has issued a new rule updating an Airworthiness Directive (AD) for Airbus Helicopters Model H160-B due to concerns about the axial play of the rotating scissors spherical bearings. This updated directive requires additional inspections, extends the list of affected helicopter parts, and outlines reporting requirements for inspection outcomes. This rule is essential for maintaining helicopter safety, with the new compliance measures coming into effect on April 25, 2025. The FAA has made these changes in response to updates from the European Union Aviation Safety Agency, ensuring alignment with international safety standards.

    Simple Explanation

    The FAA, a safety group for flying things, wants to make sure all parts of certain helicopters, called Airbus H160-B, work really well so they won't break. They’re asking for extra checks and reports to make sure everything is safe and working properly.

  • 2025-03983 — Airworthiness Directives; Safran Helicopter Engines, S.A. (Type Certificate Previously Held by Turbomeca, S.A.) Engines
    Type:Proposed Rule
    Citation:90 FR 11914
    Reading Time:about 10 minutes

    The Federal Aviation Administration (FAA) is proposing a new airworthiness directive (AD) for certain models of Safran Helicopter Engines. This proposal arose from findings that some high-pressure turbine blades might have defects due to manufacturing changes, which could lead to mechanical failures. To prevent this issue, the AD requires replacing the faulty turbine blades as detailed in a European safety agency directive. Interested parties have until April 28, 2025, to provide comments on the proposed rule.

    Simple Explanation

    The FAA wants to make sure helicopter engines are safe, so they are telling everyone to change some parts called turbine blades because they might break. People have until April 28, 2025, to say what they think about this new rule.

  • 2021-03063 — Airworthiness Directives; Airbus Helicopters
    💰
    Type:Rule
    Citation:86 FR 9433
    Reading Time:about 13 minutes

    The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) affecting various models of Airbus Helicopters, prompted by the in-flight loss of a sliding door. This AD mandates an inspection of the sliding doors' upper rail and front roller, requiring replacement or service removal if faults are detected. The rule is to prevent potential harm to the helicopter or people on the ground, with compliance required within 30 hours of service use from the rule's effective date, March 3, 2021. Comments on the directive are requested by April 2, 2021.

    Simple Explanation

    The people who make rules for flying helicopters noticed that some helicopter doors could fall off while flying, which is very dangerous. So, they made a new rule telling helicopter owners to check the doors carefully and fix or change some parts if needed, to keep everyone safe.

  • 2021-03659 — Airworthiness Directives; Bell Textron Canada Limited (Type Certificate Previously Held by Bell Helicopter Textron Canada Limited) Helicopters
    Type:Rule
    Citation:86 FR 11415
    Reading Time:about 8 minutes

    The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for certain Bell Textron Canada Limited Model 429 helicopters due to a newly introduced life limit for the centrifugal force bearing (CFB). This directive mandates determining the accumulated retirement index number (RIN) and removing the CFB when it reaches 8,000 RIN to prevent potential risks like excessive vibration and loss of control. Effective April 1, 2021, this rule aims to enhance flight safety by addressing this unsafe condition. The FAA found no significant economic impact from this rule and allowed minimal public comments during its proposal stage.

    Simple Explanation

    The FAA has a new rule for certain Bell helicopters, saying that a part called the "centrifugal force bearing" must be changed when it reaches a specific number called "8,000 RIN" to keep the helicopters safe and prevent problems like shaking or losing control. This rule starts on April 1, 2021, and helps make sure flying these helicopters stays as safe as possible.
