Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate previously held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes

FAA / Federal Register · 2020-09946

The FAA is superseding Airworthiness Directive (AD) 2018-25- 04, which applied to certain C Series Aircraft Limited Partnership (CSALP) Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2018-25-04 required repetitive inspections for any dislodged blow-out panel in the forward and aft cargo compartments, reporting of the inspection findings, and reinstallation if necessary. This new AD continues to require repetitive inspections, with a revised inspection interval, for affected panels that have not been replaced. This new AD also requires the replacement of affected blow-out panels with redesigned panels, which terminates the inspection requirement. This new AD also revises the applicability by removing certain airplanes. This AD was prompted by reports of dislodged cargo compartment blow-out panels. The FAA is issuing this AD to address the unsafe condition on these products.
