Notice of proposed rulemaking (NPRM).

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-500-1A10 and BD-500-1A11 airplanes. This proposed AD was prompted by reports of dislodged cargo compartment blow-out panels. This proposed AD would require repetitive inspections for any dislodged blow-out panel in the forward and aft cargo compartments, reporting of the inspection findings, and re-installation if necessary. We are proposing this AD to address the unsafe condition on these products.
