Airworthiness Directive 2019-02-01
one-timeAirworthiness Directives; General Electric Company Turbofan Engines
What this AD requires
We are superseding Airworthiness Directive (AD) 2018-16-07, which applied to certain General Electric Company (GE) GEnx turbofan engines. AD 2018-16-07 required removal and replacement of affected high-pressure turbine (HPT) stator cases (HPT cases). This AD retains those requirements, but reduces certain compliance times. This AD was prompted by the discovery of a quality escape at a manufacturing facility and a determination that the compliance time for the removal and replacement of certain HPT cases must be reduced. We are issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2019-02-01 applies to
Applies only to engines with HPT stator case, P/N 2302M90G04, with a serial number listed in Table 1, 2, or 3 in the Planning Information section of GE SB GEnx-2B S/B 72-0360, Revision 04, dated December 4, 2018, or GE SB GEnx-1B S/B 72-0424, Revision 04, dated December 3, 2018, installed (specific serial numbers not included in provided applicability text).
Whether AD 2019-02-01 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.
