What the agency says
The FAA is adopting a new airworthiness directive (AD) for all Bombardier Inc. Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600- 2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This AD was prompted by a report of uncommanded nose wheel steering upon landing with touchdown on the runway centerline. This AD requires replacing the nosewheel steering rudder pedal potentiometer universal coupling setscrews. This AD also requires revising the existing maintenance or inspection program, as applicable, to incorporate new life limits for the setscrews. The FAA is issuing this AD to address the unsafe condition on these products.
