Airworthiness Directive 2018-16-07
one-timeAirworthiness Directives; General Electric Company Turbofan Engines
What this AD requires
We are adopting a new airworthiness directive (AD) for certain General Electric Company (GE) GEnx-1B54, -1B58, -1B64, -1B67, -1B70, - 1B54/P1, -1B58/P1, -1B64/P1, -1B67/ P1, -1B70/P1, -1B54/P2, -1B58/P2, -1B64/P2, -1B67/P2, -1B70/P2, -1B70C/ P1, -1B70/72/P1, -1B70/75/P1, -1B74/75/P1, -1B75/P1, -1B70C/P2, -1B70/ 72/P2, -1B70/75/P2, -1B74/75/P2, -1B75/P2, -1B76/P2, -1B76A/P2, -1B78/ P2, -2B67, -2B67B, and -2B67/P turbofan engines. This AD requires removal of affected high-pressure turbine (HPT) stator cases (HPT cases) from service and their replacement with a part eligible for installation. This AD was prompted by the discovery of a quality escape at a manufacturing facility. We are issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2018-16-07 applies to
Applies only when a high-pressure turbine (HPT) stator case, P/N 2302M90G04, with a serial number listed in Table 1, 2, or 3 of GE Service Bulletin (SB) GEnx-2B S/B 72-0360, Revision 03, dated June 29, 2018, or GEnx-1B S/B 72-0424, Revision 03, dated June 29, 2018, is installed.
Whether AD 2018-16-07 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.
