We propose to supersede Airworthiness Directive (AD) 2010-14- 05, which applies to certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. AD 2010-14-05 requires inspection for the part numbers of the system and brake accumulators, and repetitive replacement of affected accumulators. Since we issued AD 2010-14-05, we have determined that new or more restrictive airworthiness limitations, as well as additional actions, are necessary to address the unsafe condition. In addition to the requirements of AD 2010-14-05, this proposed AD would require relocating the accumulators and revising the maintenance or inspection program to incorporate new or more restrictive airworthiness limitations. This proposed AD would also add optional terminating action for certain airplanes. We are proposing this AD to address the unsafe condition on these products.
