Airworthiness Directive 2022-04-07
one-timeAirworthiness Directives; General Electric Company Turbofan Engines
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) GEnx-1B64, -1B64/P1, -1B64/P2, - 1B67, -1B67/P1, -1B67/P2, -1B70, -1B70/75/P1, -1B70/75/P2, -1B70/P1, - 1B70/P2, -1B70C/P1, -1B70C/P2, -1B74/75/P1, -1B74/75/P2, -1B76/P2, - 1B76A/P2, GEnx-2B67, -2B67B, and -2B67/P model turbofan engines. This AD was prompted by an in-flight shutdown (IFSD) of an engine and subsequent investigation by the manufacturer that revealed an improperly torqued fuel metering unit (FMU) bypass valve (BPV) plug. This AD requires a shim check inspection of the FMU BPV plug and, depending on the results of the inspection, replacement of the FMU. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2022-04-07 applies to
Applies only with (1) a fuel metering unit (FMU) VIN 8062-1094 P/N 2122M20P07, VIN 8062-1176 P/N 2122M20P08, VIN 8062-1106 P/N 2459M17P01, or VIN 8062-1177 P/N 2459M17P02 installed, and (2) that FMU having a serial number identified in Paragraph 4, Appendix A, Table 1 of GE GEnx-1B SB 73-0100 R00 (dated December 3, 2021) or GE GEnx-2B SB 73-0092 R00 (dated December 3, 2021).
Whether AD 2022-04-07 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.
