Notice of proposed rulemaking (NPRM).
Summary
The Federal Aviation Administration (FAA) is proposing a new safety rule that would require certain Airbus A350‑900 and A350‑1000 aircraft to be upgraded after a series of hydraulic pump failures were reported. The rule would call for changes to the aircraft’s hydraulic‑monitoring software, updates to the flight manual, and replacement of specific pump components. It also would ban the installation of the faulty parts and the use of the problematic software on these airplanes, aiming to prevent future pump failures that could affect the aircraft’s handling and safety. This proposal comes from the FAA, the U.S. agency that oversees aviation safety, and it applies to operators of the affected Airbus A350 models that are registered in the United States. Airlines, maintenance providers, and owners of these planes will need to comply with the required modifications if the rule is finalized. The notice was published on September 9, 2026, and comments must be submitted by October 26, 2026. After the comment period closes, the FAA will review the feedback and decide whether to adopt the rule as written, modify it, or take another action. If adopted, the FAA will issue a final airworthiness directive with a compliance timeline that airlines will have to follow to keep their aircraft airworthy.

Official abstract
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.
