Airbus A350s Require Urgent Fastener Coating Fixes
Published Date: 6/4/2026
Rule
Summary
The FAA is requiring fixes on certain Airbus A350-941 airplanes because some fasteners didn’t get the right protective coating during production, which could cause safety issues. Airlines must replace affected parts and add extra protection by July 9, 2026. This update helps keep flights safe without causing big delays or costs.
Analyzed Economic Effects
3 provisions identified: 2 benefits, 1 costs, 0 mixed.
Mandatory Fastener Replacement by July 9, 2026
If you operate an Airbus A350-941 (as identified in EASA AD 2025-0210), you must replace each affected fastener and apply additional head nut cap protection (sealant and corrosion-inhibiting protection) in the center wing box and belly fairing junction. These actions must be done in accordance with EASA AD 2025-0210 (as incorporated) and are effective July 9, 2026.
Lightning-Related Fuel Tank Explosion Risk
The AD responds to a condition where some fasteners were produced without double overcoating sealant and some fasteners are susceptible to rotation; this could lead to loss of fastener clamping and cracking of the nut sealant cover, and in the case of a lightning strike could create a risk of fuel tank explosion and consequent loss of the airplane.
Estimated Compliance Cost to U.S. Operators
The FAA estimates this AD affects 5 U.S.-registered A350-941 airplanes. Estimated cost per airplane is $5,920 (64 work-hours × $85/hour = $5,440 labor plus $480 parts), for an estimated total cost to U.S. operators of $29,600. The AD is effective July 9, 2026.
