AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Final rule.
SUMMARY:
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a determination that the applicable aircraft flight manual (AFM) was providing an incorrect value for maximum cumulative taxi time in freezing fog conditions. This AD requires revising the existing AFM to provide the flightcrew with normal procedures to follow under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
DATES:
This AD is effective August 5, 2025.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of August 5, 2025.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus SAS Model A350-941 and -1041 airplanes. The NPRM was published in the
Federal Register
on March 26, 2025 (90 FR 13707). The NPRM was prompted by AD 2024-0190, dated October 10, 2024; corrected October 11, 2024, issued by EASA, which is the Technical Agent for the Member States of the European Union (EASA AD 2024-0190) (also referred to as “the MCAI”). The MCAI states the applicable AFM was providing an incorrect value for maximum cumulative taxi time in freezing fog conditions, which could lead to multiple engine surges in a critical flight phase and possibly result in loss of control of the airplane.
