FAA Mandates Clamp Upgrades for Airbus Oxygen Safety
Published Date: 2/13/2026
Proposed Rule
Summary
The FAA wants all Airbus A350-941 and -1041 planes to swap out old clamps holding oxygen generators for new ones with safer specs. This change stops using outdated maintenance steps and blocks installing the old parts to keep flights safe. Airlines need to comment by March 30, 2026, and get ready for these updates, which might cost some time and money but boost safety big time.
Analyzed Economic Effects
2 provisions identified: 0 benefits, 2 costs, 0 mixed.
Replace A350 Oxygen-generator Clamps
The FAA proposes to require replacing the affected chemical oxygen generator clamps on all Airbus A350-941 and -1041 airplanes in accordance with EASA AD 2025-0138 (dated July 1, 2025) and would prohibit installing the affected parts. The FAA estimates this AD would affect 38 U.S.-registered airplanes, with up to 350 work-hours (at $85/hour = $29,750) plus up to $230,300 in parts per airplane, for a total cost per airplane of up to $260,050 and an estimated cost to U.S. operators of up to $9,881,900.
Ban on Older A350 Maintenance Procedure
The proposed AD would prohibit performing maintenance actions using maintenance procedure task A350-A-35-21-36-A0001-720A-A dated earlier than October 2024. If you operate Airbus A350-941 or -1041 airplanes, you must use the updated procedures and not rely on the older task versions dated before October 2024.
