✈️Proposed Airworthiness Directive for Bombardier Airplanes
Airworthiness Directives; Bombardier Inc. Airplanes
Summary
The FAA proposes to adopt 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 proposed AD was prompted by a report of uncommanded nose wheel steering upon landing with touchdown on the runway centerline. This proposed AD would require replacing the nosewheel steering potentiometer universal coupling setscrews. This proposed AD would also require revising the existing maintenance or inspection program, as applicable, to incorporate new life limits for the setscrews. The FAA is proposing this AD to address the unsafe condition on these products.

The proposed airworthiness directive (AD) requires business owners operating affected Bombardier models to undertake necessary repairs, impacting compliance and operational costs. The estimated financial impacts include direct costs of $380 per aircraft and potential maintenance program revisions costing an average of $7,650 per operator, which could affect budgets and financial planning.
