Airworthiness Directive · Amendment 39-23470 · Engine
Safran Helicopter Engines, S.A. Engines
This AD applies to all Safran Helicopter Engines, S.A. Model Arrius 2B2 engines.
The FAA is superseding Airworthiness Directive (AD) 2023-15-03 for all Safran Helicopter Engines, S.A. (Safran) Model Arrius 2B2 engines. AD 2023-15-03 required revising the airworthiness limitations section (ALS) of the existing engine maintenance manual (EMM) or instructions for continued airworthiness (ICA) and the existing approved maintenance or inspection program, as applicable, by incorporating the actions and associated thresholds and intervals, including life limits. Since the FAA issued AD 2023-15-03, the manufacturer has revised the ALS of the existing maintenance and overhaul manuals, introducing new and more restrictive instructions and maintenance tasks. This AD requires updating the ALS of the existing EMM or ICA and the existing approved maintenance or inspection program, as applicable, by incorporating the actions and associated thresholds and intervals, including life limits. The FAA is issuing this AD to address the unsafe condition on these products.
(1) Except as specified in paragraph (h) of this AD, perform all required actions within the compliance times specified in, and in accordance with, European Union Aviation Safety Agency AD 2026-0027, dated February 11, 2026 (EASA AD 2026-0027).
(2) The action required by paragraph (g)(1) of this AD may be performed by the owner/operator (pilot) holding at least a private pilot certificate and must be entered into the aircraft records showing compliance with this AD in accordance with 14 CFR 43.9(a) and 91.417(a)(2)(v). The record must be maintained as required by 14 CFR 91.417, 121.380, or 135.439.
(1) Where EASA AD 2026-0027 refers to its effective date, this AD requires using the effective date of this AD.
(2) This AD does not require compliance with paragraphs (1), (2), (4), and (5) of EASA AD 2026-0027.
(3) Where paragraph (3) of EASA AD 2026-0027 specifies “Within 12 months after the effective date of this AD, revise the approved AMP,” this AD requires replacing that text with “Within 90 days after the effective date of this AD, revise the airworthiness limitations section of the existing engine maintenance manual or instructions for continued airworthiness and the existing approved maintenance or inspection program, as applicable.”
(4) This AD does not adopt the “Remarks” section of EASA AD 2026-0027.
After performing the actions required by paragraph (g) of this AD, no alternative actions and associated thresholds and intervals, including life limits, are allowed unless they are approved as specified in the provisions of the “Ref. Publications” section of EASA AD 2026-0027.
