What this AD requires

The MCAI describes the unsafe condition as:
Which aircraft AD 2009-08-08 applies to
Applies only to engines with power turbine module M04 installed, as listed by serial number in Figure 1 of Turbomeca Alert MSB No. A292 72 0827 (Arriel 1B, 1D, 1D1) or MSB No. A292 72 2833 (Arriel 2B, 2B1), Version A, dated March 20, 2009. These engines are installed on, but not limited to, Eurocopter AS 350 B, AS 350 BA, AS 350 B1, AS 350 B2, AS 350 B3, and EC 130 B4 helicopters.
Whether AD 2009-08-08 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
