Models named: M601E-11, M601E-11A, M601E-11AS, M601E-11S. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
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 M601E-11, M601E-11A, M601E-11AS, and M601E-11S engines with a centrifugal compressor case having part number (P/N) M601-154.61 installed.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
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 2021-0125R1, dated January 30, 2023 (EASA AD 2021-0125R1).
Unsafe condition
This AD was prompted by the manufacturer determining that the life limit of a compressor case having P/N M601-154.61 is not listed in the airworthiness limitations section of the existing engine maintenance manual. 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.
Affected ADs
This AD replaces AD 2021-13-07, Amendment 39-21612 (86 FR 31601, June 15, 2021) (AD 2021-13-07).
