## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and A350-1041 airplanes. This proposed AD was prompted by reports of failure of hydraulic engine driven pumps (EDPs) of the standard EDP-06. This proposed AD would require, depending on airplane configuration, modifying the hydraulic monitoring and control application (HMCA), accomplishing applicable concurrent requirements, revising the existing airplane flight manual (AFM), and replacing affected parts. This proposed AD would also prohibit the installation of affected parts and prohibit the installation of certain HMCA software. The FAA is proposing this AD to address the unsafe condition on these products.
