Airworthiness Directive 2023-20-08
one-timeAirworthiness Directives; General Electric Company Engines
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) Model CF6-80C2B1F, CF6-80C2B2F, CF6-80C2B4F, CF6-80C2B5F, CF6-80C2B6F, CF6-80C2B7F, and CF6-80C2K1F engines. This AD was prompted by an uncontained engine fire and consequent manufacturer investigation, which revealed that certain bearings were installed improperly. This AD requires inspection of the magnetic chip detector (MCD) probe tip for metallic particles and, if necessary, removal of the engine from service. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2023-20-08 applies to
Applies only to engines with engine serial numbers in the listed ranges that have accumulated less than 400 engine cycles since new (CSN); source text truncated after '...on the'
Whether AD 2023-20-08 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.
