What the agency says
The FAA is superseding Airworthiness Directive (AD) 2024-04- 06, which applied to certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2024-04-06 required repetitive operational checks of the gravity cross flow shut-off valve and, for certain airplanes, a one-time inspection of the motive flow fuel-feed tubes at the clamp blocks location and applicable corrective actions. Since the FAA issued AD 2024-04-06, the manufacturer developed additional corrective actions. This AD continues to require the actions in AD 2024-04-06 and requires replacement of the saddle clamp, inspection of the motive flow fuel-feed tubes, and applicable corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
