The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by reports that during airplane wing fatigue testing, fatigue cracks were found on the lower right-hand-side wing plank at the end of the integrally machined stringers, which led to a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require, for certain airplanes, revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.
