Airworthiness Directive 2007-24-10
one-timeAirworthiness Directives; Turbomeca Arriel 2S1 and 2S2 Turboshaft Engines
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) provided by the European Aviation Safety Agency (EASA) to identify and correct an unsafe condition on Turbomeca Arriel 2S1 and 2S2 turboshaft engines. The MCAI states the following:
Which aircraft AD 2007-24-10 applies to
Applies to all serial numbers of Arriel 2S1 and 2S2 engines that have a hydro mechanical unit (HMU) installed that was manufactured, repaired, or overhauled before December 8, 2006.
Whether AD 2007-24-10 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.
