  • 2021-01780 — Airworthiness Directives; Safran Helicopter Engines, S.A. (Type Certificate Previously Held by Turbomeca, S.A.) Turboshaft Engines
    Type:Proposed Rule
    Citation:86 FR 10501
    Reading Time:about 13 minutes

    The FAA is proposing a new airworthiness directive (AD) for certain models of Safran Helicopter Engines. This AD is in response to reports of non-conforming fuel filter pre-blockage pressure switches, which might not activate correctly if there's fuel contamination, potentially leading to engine shutdowns during flight. The proposed rules include routine visual inspections and operational tests of these pressure switches, and replacing them if necessary, to ensure that the engines remain safe to operate. Comments on the proposal are invited by April 8, 2021.

    Simple Explanation

    The FAA is making a new rule to check and possibly fix a part in certain helicopter engines so they don't stop working in the air. This rule wants people to look at and test the part regularly to make sure everything is safe.

  • 2025-03013 — Airworthiness Directives; Safran Helicopter Engines, S.A. (Type Certificate Previously Held by Turbomeca, S.A.) Engines
    Type:Proposed Rule
    Citation:90 FR 10617
    Reading Time:about 12 minutes

    The Federal Aviation Administration (FAA) is proposing a new airworthiness directive (AD) for all Safran Helicopter Engines, Model ARRIUS 2B2. This proposal is in response to data indicating that a key engine component, the preference injector, may clog due to fuel coking, which could lead to engine failure and loss of helicopter control. The AD would require testing, possible replacement of the injector, and a software upgrade. The FAA invites public comments on this proposed rule by April 11, 2025.

    Simple Explanation

    The FAA wants to make sure certain helicopter engines stay safe by checking and possibly fixing a part that could get clogged. They are asking people to share their thoughts about this plan until April 11, 2025.

  • 2021-03777 — Airworthiness Directives; Safran Helicopter Engines, S.A. (Type Certificate Previously Held by Turbomeca, S.A.) Turboshaft Engines
    Type:Proposed Rule
    Citation:86 FR 11662
    Reading Time:about 9 minutes

    The Federal Aviation Administration (FAA) is proposing a new airworthiness directive for certain Safran Helicopter Engines, specifically the Arriel 2C and Arriel 2S1 model turboshaft engines. This proposed directive is in response to reports of error messages caused by a defective varnish on the digital engine control unit (DECU) circuit board, which can lead to malfunctions. The directive would require replacing affected DECUs to prevent potential loss of engine control. The FAA is accepting comments on this proposal until April 12, 2021.

    Simple Explanation

    The FAA wants to make sure certain helicopter engines are safe because a part inside can get messed up and cause problems. They say replacing this part can stop these problems, and they want people to tell them what they think about this idea by April 12, 2021.

  • 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.
