Resumo
The FAA proposes to adopt a new airworthiness directive (AD) for all Safran Helicopter Engines, S.A. Arriel 2C and Arriel 2S1 model turboshaft engines. This proposed AD was prompted by reports of error messages on the full authority digital engine control (FADEC) B digital engine control unit (DECU), caused by blistering of the varnish on the DECU circuit board. This proposed AD would require the replacement of certain FADEC B DECUs. The FAA is proposing this AD to address the unsafe condition on these products.
