## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Leonardo S.p.a. (Leonardo) Model AW109SP helicopters. This proposed AD was prompted by reports of an ineligible hydraulic pump being installed on Model AW109SP helicopters. This proposed AD would require inspecting each hydraulic pump for damage and, depending on the inspections results, removing parts from service and accomplishing other corrective actions. This proposed AD would also require removing certain parts from service before they exceed their life limits. The proposed corrective actions would be required to be accomplished as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
