Airworthiness Directive 2011-05-08

What this AD requires
This action supersedes emergency airworthiness directive (AD) 2011-05-51 that was sent previously to all known U.S. owners and operators of the products listed above. That AD requires inspecting the fuel ejector in the body of the fuel ejector assembly for proper installation by checking that the circlip is properly seated in its groove. That AD was prompted by three reports of incorrectly assembled low-pressure fuel system ejectors; with one of them resulting in an uncommanded engine in-flight shutdown. This AD requires the same actions and compliance times as the emergency AD, after receipt of the emergency AD, and expands the AD applicability by including helicopters having one or two affected engines and experiencing no starting difficulties. 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 2011-05-08 applies to
Applies only to engines that have incorporated Turbomeca Service Bulletin (SB) No. 292 73 0826, Version A, dated October 13, 2009, or incorporated Turbomeca Internal Consign No. 298468.
Whether AD 2011-05-08 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.
