Summary

We propose to supersede airworthiness directive (AD) 2013-11- 09 that applies to all Safran Helicopter Engines, S.A., Arrius 2B1 and 2F turboshaft engines. Depending on the engine model, AD 2013-11-09 requires the repetitive replacement of the fuel injector manifolds and privilege injector, or only the privilege injector. Since we issued AD 2013-11-09, we received reports of engine flameouts as a result of reduced fuel flow due to the presence of coking. This proposed AD would retain the repetitive hardware replacement requirements of AD 2013-11- 09, but only allow replacement pipe injector preferred assembly, part number (P/N) 0 319 73 044 0, on the Arrius 2F engines. We are proposing this AD to correct the unsafe condition on these products.
