The FAA's summary their words, unchanged

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601 Variant), and CL-600-2B16 (CL-601-3A and CL-601-3R Variants) airplanes. This AD was prompted by a report of laminated shims that may have been improperly installed at a certain wing tie beam. This AD requires revising the maintenance or inspection program to incorporate certification maintenance requirement tasks that introduce revised checks of the tie beam. We are issuing this AD to address the unsafe condition on these products.
