Airworthiness Directive · Amendment 39-22483 · Propeller governor
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. Model M601E-11AS, M601E-11S, H75-100, H80-100, and H85-100 engines, as identified in European Union Aviation Safety Agency (EASA) AD 2022-0234, dated December 1, 2022 (EASA AD 2022-0234).
The FAA is adopting a new airworthiness directive (AD) 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 M601E-11AS, M601E-11S, H75-100, H80-100, and H85-100 engines. This AD is prompted by reports of multiple failures of the needle bearing installed in propeller governors having part numbers (P/Ns) P-W11-1 or P-W11-2, caused by self-generated debris from the needle bearing, which led to oil contamination. This AD requires replacement of the affected propeller governors with a redesigned propeller governor and prohibits installation of the affected propeller governors, 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.
Except as specified in paragraph (h) of this AD: Perform all required actions and compliance times specified in, and in accordance with, EASA AD 2022-0234.
(1) Where EASA AD 2022-0234 specifies compliance from its effective date, this AD requires using the effective date of this AD.
(2) This AD does not adopt the Remarks paragraph of EASA AD 2022-0234.
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 2022-0234.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
