What this AD requires
The FAA is adopting a new airworthiness directive (AD) for
Which aircraft AD 2010-12-03 applies to
Applies only to engines with 25-degree midspan shroud fan blades of the listed part numbers, or fan blade pairs of the listed part numbers, installed. Engines marked CFM56-3-B1 on the data plate are included as CFM56-3; engines marked CFM56-3B-2 are included as CFM56-3B.
Whether AD 2010-12-03 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

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.
