FAA airworthiness directive for Airbus Canada BD-500 aircraft
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
The rule requires added fuel-system checks and repairs on certain Airbus Canada BD-500-1A10 and BD-500-1A11 airplanes. It keeps earlier requirements for repeated checks of the gravity cross-flow shut-off valve and some fuel-feed tube inspections, then adds new work because the manufacturer developed further fixes. Airlines and operators using affected aircraft must replace the saddle clamp, inspect motive-flow fuel-feed tubes, and complete any needed corrective actions. The rule takes effect July 1, 2026, and is aimed at reducing a fuel-system safety risk.
