Airworthiness Directive 2019-02-04
one-timeAirworthiness Directives; Engine Alliance Turbofan Engines
What this AD requires
We are superseding Airworthiness Directive (AD) 2018-22-05, which applied to Engine Alliance (EA) GP7270, GP7272, and GP7277 turbofan engines with a certain high-pressure turbine (HPT) case installed. AD 2018-22-05 required removal of affected HPT stator cases (HPT cases) from service and their replacement with a part eligible for installation. This AD retains these requirements, reduces the compliance times for the removal and replacement of certain HPT cases, and identifies additional affected parts that must be removed and replaced. This AD was prompted by the discovery of a quality escape at a manufacturing facility involving unapproved welds on HPT cases. Subsequent additional findings suggested the need for an updated risk analysis, resulting in reduced compliance times for those parts and the identification of additional affected parts. We are issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2019-02-04 applies to
Applies only to engines with high-pressure turbine (HPT) stator case, P/N 2060M40G02 or 2137M29G01, with an HPT case serial number listed in Table 1 of EA Alert SB EAGP7-A72-401, Revision 1, dated December 13, 2018, and in Table 1 of EA SB EAGP7-72-399, dated June 4, 2018 (specific serial numbers not included in provided applicability text).
Whether AD 2019-02-04 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
