## Summary

We propose to supersede Airworthiness Directive (AD) 2008-24- 14, which applies to all Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. AD 2008-24-14 requires revising the instructions for continued airworthiness to incorporate certain airworthiness limitations for the main landing gear (MLG) trunnion fitting assembly. Since we issued AD 2008-24-14, new airworthiness limitation (AWL) tasks have been introduced with revised inspection, modification, and safe-life requirements. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate certain AWLs. It would also require reworking the trunnion fitting in order to meet new structural safe-life limits. We are proposing this AD to address the unsafe condition on these products.
