ACTION: Final rule. SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 airplanes. This AD was prompted by an inspection that found several anodic burns on the main landing gear (MLG) bogie beam axles following a high velocity oxygen-fuel (HVOF) stripping process. This AD requires replacement of affected MLG bogie beam axles and prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective July 11, 2025. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of July 11, 2025.

The NPRM was published in the Federal Register on February 20, 2025 (90 FR 9955). The NPRM was prompted by AD 2024-0156, dated August 13, 2024, issued by EASA, which is the Technical Agent for the Member States of the European Union (EASA AD 2024-0156) (also referred to as “the MCAI”). The MCAI states that during an inspection conducted at an A350 MLG bogie beam axle supplier, several anodic burns were observed following an HVOF stripping process. Additional MLG bogie beam axle inspections using the same HVOF stripping process at the same facility revealed similar findings. The analysis revealed a detrimental imp…
