Airworthiness Directive 2020-08-01
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) CF34-1A, CF34-3A, CF34-3A1, CF34- 3A2, CF34-3B, and CF34-3B1 model turbofan engines. This AD was prompted by an in-flight failure of a fan blade that led to an in-flight shutdown. This AD requires removal and replacement of the affected fan blades. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2020-08-01 applies to
Applies only to engines with a fan blade part number listed in GE Service Bulletin CF34-AL S/B 72-0314 (dated September 27, 2017) or GE Service Bulletin CF34-BJ S/B 72-0306 (dated September 27, 2017), and with a serial number listed in Appendix A of the applicable service bulletin.
Whether AD 2020-08-01 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.
