Airbus A330 Fire Detectors Tainted: Replace Them Now

Published Date: 3/4/2025

Rule

Summary

The FAA is making a new rule for certain Airbus A330 airplanes because some engine fire detector parts got contaminated and might not work right. Airlines must replace these parts and can’t use the old ones anymore, starting April 8, 2025. This keeps flights safe but might cost some money and time for the fixes.

Analyzed Economic Effects

3 provisions identified: 2 benefits, 1 costs, 0 mixed.

Airlines must replace contaminated fire-detector parts

If you operate the listed Airbus A330 models, you must replace affected engine pylon fire detectors and may not install the affected parts starting April 8, 2025. The FAA estimates the work is 7 labor-hours ($595) plus $828 in parts, for a total of $1,423 per airplane and $8,538 for the 6 U.S.-registered airplanes affected.

Reduces risk of undetected engine-pylon fires

You (passenger or crew) benefit from increased safety because the AD addresses contamination of the advanced pneumatic detector pressure switch on engine pylon fire detectors to reduce the chance of an undetected fire. The AD targets specific Airbus A330-200/-200 Freighter/-300 series airplanes and is effective April 8, 2025.

FAA removed EASA's return-of-parts obligation

Although the EASA AD directs operators to send affected pylon fire detectors to Kidde Technologies Inc., the FAA AD does not include that return requirement. Operators therefore are not required by this FAA rule to ship affected detectors to Kidde.
