FAA Proposes Rust Checks and Fuel-Vapor Barriers for Airbus Planes

## Summary

The FAA wants to update safety rules for certain Airbus Canada airplanes to keep them flying safely. They’re asking for extra checks on parts that could get rusty and adding a new fuel vapor barrier to prevent problems. Owners need to comment by December 28, 2026, and be ready for these inspections and fixes, which help avoid costly repairs down the line.

## Abstract

The FAA proposes to supersede Airworthiness Directive (AD) 2021-13-20, which applies to certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2021-13-20 requires inspecting the waste box, waste access doubler, and waste service door for corrosion, and doing applicable on-condition actions. Since the FAA issued AD 2021-13-20, the FAA has determined that a full secondary fuel vapor barrier must be applied. This proposed AD would retain all requirements of AD 2021-13-20 and would also require, for certain airplanes, an additional inspection of the waste box, waste access doubler, and waste service door for corrosion, and applicable on- condition actions. The FAA is proposing this AD to address the unsafe condition on these products.

## Effects PRIA read

- New inspections and fuel‑vapor barrier required: cost, high. If you operate Airbus Canada Model BD-500-1A10 or BD-500-1A11 airplanes, this proposed rule would keep the inspections required by AD 2021-13-20 and add additional inspections for certain airplanes and a requirement to apply a full secondary fuel vapor barrier to the waste box. The FAA requires com…
- Corrosion must be repaired before further flight: cost, medium. This AD requires that any corrosion found on the waste box, waste access doubler, or waste service door must be repaired before the airplane is flown again. The proposed rule replaces language in the Transport Canada AD to explicitly require that corrosion repairs be done before further flight afte…
- FAA cost estimate: labor and U.S. fleet impact: cost, high. The FAA estimates this AD would affect 32 U.S.-registered airplanes. The FAA estimates labor for each required action is 8 work-hours at $85 per hour (8 x $85 = $680 per airplane per action), giving $21,760 total cost to U.S. operators per action for the 32 airplanes; parts costs and on-condition r…
