Airworthiness Directive 2002-01-02
one-timeAirworthiness Directives; Turbomeca S.A. Arrius 1A Turboshaft Engines
What this AD requires
This amendment adopts a new airworthiness directive (AD) that is applicable to Turbomeca S.A. Arrius 1A turboshaft engines. This action requires replacement of the 10 main fuel injectors in Arrius 1A engines with new or overhauled injectors. This amendment is prompted by routine inspections conducted in the repair workshop demonstrating that some main fuel injectors were partially or totally blocked. The actions specified in this AD are intended to prevent blocked main fuel injectors that could lead to engine flameout during engine deceleration or that could prevent the engine from obtaining the 2\1/2\ minute one engine inoperative (OEI) power.
Which aircraft AD 2002-01-02 applies to
Applies to Arrius 1A turboshaft engines; requires replacing all 10 main fuel injectors on a schedule keyed to accumulated operating hours since new or last overhaul (before further flight if over 1,350 hours; otherwise before reaching 1,350 hours), to prevent blocked injectors causing flameout or failure to reach 2-1/2 minute OEI power. See Turbomeca (Group Snecma) Alert SB No. A319 73 0071; also addressed by French DGAC AD 2000-532(A).
Whether AD 2002-01-02 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.
