The FAA's summary their words, unchanged

The FAA is superseding Airworthiness Directive (AD) 2021-13-07 for all GE Aviation Czech s.r.o. (GEAC) (type certificate previously held by WALTER Engine a.s., Walter a.s., and MOTORLET a.s.) Model M601D-11, M601E-11, M601E-11A, M601E-11AS, M601E-11S, and M601F engines. AD 2021-13-07 required recalculating the life of critical parts and, depending on the results of the recalculation, replacing those critical parts. AD 2021-13-07 also required replacing a certain compressor case. Since the FAA issued AD 2021-13-07, the manufacturer published the airworthiness limitations section (ALS) of the existing engine maintenance manual (EMM), which includes the calculations for the life of critical parts addressed by AD 2021-13-07 and prompted this AD. This AD continues to require the replacement of a certain centrifugal compressor case. This AD also includes an additional part number as an option for the replacement, and limits the applicability of this AD, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

Removing Airworthiness Directive 2021-13-07, Amendment 39-21612 (86 FR 31601, June 15, 2021); and b. Adding the following new airworthiness directive: 2024-02-04 GE Aviation Czech s.r.o. (Type Certificate Previously held by WALTER Engines a.s., Walter a.s., and MOTORLET a.s.): Amendment 39-22668; Docket No. FAA-2023-2002; Project Identifier MCAI-2023-00176-E. (a) Effective Date This airworthiness directive (AD) is effective March 28, 2024. (b) Affected ADs This AD replaces AD 2021-13-07, Amendment 39-21612 (86 FR 31601, June 15, 2021) (AD 2021-13-07). (c) Applicability 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.)

(d) Subject Joint Aircraft System Component (JASC) Code 7230, Turbine Engine Compressor Section.

The FAA is issuing this AD to prevent the failure of the engine. The unsafe condition, if not addressed, could result in uncontained release of a critical part, damage to the engine, and damage to the airplane.
