Airbus Engine Bottles Face Crack Detection Mandate
Published Date: 2/20/2026
Proposed Rule
Summary
The FAA wants to fix a safety problem on all Airbus A330-841 and A330-941 planes because some engine fire extinguisher bottles have cracks. They’re proposing to require changes to these bottles and stop using the cracked parts to keep everyone safe. Comments on this plan are open until April 6, 2026, and airlines will need to act soon to avoid risks and extra costs.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
Prevents Fire Extinguisher Failures Onboard
The FAA proposes this rule because cracks were reported on the discharge outlet of certain engine fire extinguisher bottles (part number 34500063-11) on Airbus A330-841 and A330-941 airplanes; the rule requires replacing the discharge outlet to address stress corrosion cracking and prohibit installing that part number to prevent a possible extinguisher agent leak and ensure the fire extinguishing system functions as intended.
Airlines Must Replace Cracked Extinguisher Parts
If you operate Airbus A330-841 or A330-941 airplanes, the FAA would require you to modify affected engine fire extinguisher bottles by replacing the discharge outlet and to stop installing parts with part number 34500063-11, in accordance with EASA AD 2025-0034. The FAA estimates the labor for the required action at 11 work-hours x $85/hour = $935 per product and estimates the action would affect 35 U.S.-registered airplanes for a total estimated cost of $32,725; parts cost is not provided and some costs may be covered under warranty.
