## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed AD was prompted by multiple occurrences of pilot and co-pilot seats locking in a fore-aft position due to the seat fore-aft adjustment mechanism disconnecting, caused by a broken cotter pin in the seat base egress linkage. This proposed AD would require modifying the pilot and co-pilot seats by replacing the hardware of the seat base egress linkage, as specified in a Transport Canada AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
