Airworthiness Directive · Amendment 39-22654 · Engine
GE Aviation Czech s.r.o. (Type Certificate Previously Held by WALTER Engines a.s., Walter a.s., and MOTORLET a.s.) Engines
This AD applies to GE Aviation Czech s.r.o. (type certificate previously held by WALTER Engines a.s., Walter a.s., and MOTORLET a.s.) Model H75-100, H75-200, H80, H80-100, H80-200, H85-100, and H85-200 engines.
The FAA is superseding Airworthiness Directive (AD) 2023-01- 07 for all GE Aviation Czech s.r.o. (GEAC) (type certificate previously held by WALTER Engines a.s., Walter a.s., and MOTORLET a.s.) Model H75- 100, H75-200, H80, H80-100, H80-200, H85-100, and H85-200 engines. AD 2023-01-07 required revising the airworthiness limitations section (ALS) of the existing engine maintenance manual (EMM) and the operator's existing approved maintenance or inspection program, as applicable, to incorporate updated coefficients and recalculate the cycles accumulated on critical parts. Since the FAA issued AD 2023-01- 07, the manufacturer revised the ALS of the EMM to introduce new and more restrictive airworthiness limitations and associated thresholds and intervals for life-limited parts, which prompted this AD action. This AD requires revising the ALS of the existing EMM and the operator's existing approved engine maintenance or inspection program, as applicable, to incorporate new and more restrictive instructions and associated thresholds and intervals for life-limited parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). 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 (EASA) AD 2023-0021, dated January 23, 2023 (EASA AD 2023-0021).
(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 2023-0021 defines the AMP as “the approved Aircraft Maintenance Programme containing the tasks on the basis of which the scheduled maintenance is conducted to ensure the continuing airworthiness of each operated engine,” for this AD, replace that text with, “the aircraft maintenance program containing the tasks on the basis of which the scheduled maintenance is conducted to ensure the continuing airworthiness of each operated airplane.”
(2) Where EASA AD 2023-0021 defines the ALS as “the Airworthiness Limitations Section of GEAC EMM No. 0983402 Revision 25, dated November 21, 2022,” for this AD, replace that text with, “the airworthiness limitations section of GEAC EMM No. 0983402 Revision 26, dated February 1, 2023.” The ALS in Revision 26 of the EMM is unchanged from Revision 25 of the EMM.
(3) Where EASA AD 2023-0021 refers to its effective date, this AD requires using the effective date of this AD.
(4) Where paragraph (3) of EASA AD 2023-0021 specifies revising “the approved AMP within 12 months after the effective date of EASA AD 2023-0021,” replace that text with, “the ALS of the existing approved engine maintenance or inspection program, as applicable, within 90 days after the effective date of this AD.”
(5) This AD does not require compliance with paragraphs (1), (2), (4), and (5) of EASA AD 2023-0021.
(6) This AD does not adopt the Remarks paragraph of EASA AD 2023-0021.
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 2023-0021.
