The FAA amends § 39.13 by adding the following new airworthiness directive: 2022-26-01 GE Aviation Czech s.r.o (Type Certificate previously held by WALTER Engines a.s., Walter a.s., and MOTORLET a.s.): Amendment 39-22279; Docket No. FAA-2022-1239; Project Identifier MCAI-2022-00301-E. (a) Effective Date This airworthiness directive (AD) is effective January 26, 2023. (b) Affected ADs None. (c) Applicability This AD applies to GE Aviation Czech s.r.o. (GEAC) M601D-11, M601E-11, M601E-11A, M601E-11AS, M601E-11S, M601F, H75-100, H75-200, H80, H80-100, H80-200, H85-100, and H85-200 model turboprop engines installed on single-engine airplanes, with an installed combustion chamber outer liner having part numbers (P/Ns) M601-229.3, M601-229.3A, M601-229.3B, M601-229.31A, or M601-229.31B. (d) Subject Joint Aircraft System Component (JASC) Code 7240, Turbine Engine Combustion Section. (e) Unsafe Condition This AD was prompted by reports of cracks in dilution tube weld areas of the combustion chamber outer liner. The FAA is issuing this AD to prevent failure of the combustion chamber outer liner. The unsafe condition, if not addressed, could result in uncontained release of the combustion chamber outer liner, loss of engine power, and reduced control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions (1) At the next 300-hour (Type 3) engine inspection, or within 25 flight hours (FHs) after the effective date of this AD, whichever occurs later, and thereafter at intervals not to exceed 300 FHs, perform a borescope inspection (BSI) of the dilution tube weld areas of the combustion chamber outer liner in accordance with the Accomplishment Instructions, paragraph 2.1 of GEAC Alert Service Bulletin (ASB) ASB-H75-72-40-00-0056 [01], ASB-M601E-72-40-00-0113 [01], ASB-H80-72-40-00-0099 [01], ASB-M601D-72-40-00-0081 [01], ASB-M601F-72-40-00-0064 [01], ASB-M601Z-72-40-00-0063 [01], and ASB-H85-72-40-00-0045 [01] (single document; formatted as service bulletin identifier [revision number]), dated February 16, 2022 (the ASB).

(h) Terminating Action Replacing the affected combustion chamber outer liner with a combustion chamber outer liner that does not have P/N M601-229.3, M601-229.3A, M601-229.3B, M601-229.31A, or M601-229.31B, constitutes a terminating action for the repetitive inspections required by paragraph (g)(1) of this AD. (i) Conditional Part Installation (1) After the effective date of this AD, it is permissible to install an engine, having an affected combustion chamber outer liner installed, on a single-engine airplane, provided that prior to operation, the BSI required by paragraph (g)(1) of this AD is performed and, depending on the findings, the applicable corrective actions are performed as required by paragraph (g)(2) of this AD. (2) After the effective date of this AD, it is permissible to install an affected combustion chamber outer liner on the engine of a single-engine airplane, provided that it is a part eligible for installation, as defined in paragraph (j) of this AD, and provided that prior to operation, the BSI required by paragraph (g)(1) of this AD is performed and, depending on the findings, the applicable corrective actions are performed as required by paragraph (g)(2) of this AD. (j) Definitions For the purpose of this AD, a "part eligible for installation" is an affected combustion chamber outer liner, which was not previously installed on an engine, or an affected combustion chamber outer liner that, before installation, has passed an inspection (no defects found) in accordance with the Accomplishment Instructions, paragraphs 2.2 and 2.3 of the ASB, or a combustion chamber outer liner that does not have P/Ns M601-229.3, M601-229.3A, M601-229.3B, M601-229.31A, or M601-229.31B.
