What this AD requires
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Which aircraft AD 2010-11-10 applies to
Applies only to third stage turbine wheels that incorporate modification AB173 (Turbomeca SB No. 283 72 0091) or modification AB208 (Turbomeca SB No. 283 72 0117) but do not incorporate Turbomeca SB No. 283 72 805. P/Ns 0265257000, 0265257020, and 0265257060 apply at all serial numbers; P/N 0265257050 applies only to the serial numbers listed in Appendix 1 of Turbomeca MSB No. 283 72 0804, Version C, dated October 23, 2009.
Whether AD 2010-11-10 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.
