What the agency says
The FAA proposes to adopt a new airworthiness directive (AD) for all MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by the discovery of ten ultrasonic inspections associated with airworthiness limitations (AWL) tasks and structural deviation inspection requirements (SDIR) tasks potentially not detecting cracks. This proposed AD would require repetitive ultrasonic inspections of certain structural areas for cracking as specified in a Transport Canada AD, which is proposed for incorporation by reference (IBR), and repair of cracking, as applicable. This proposed AD would also prohibit use of the previous revisions of certain procedures and mandate the use of the revised procedures when performing the inspections required by the associated AWL and SDIR tasks. The FAA is proposing this AD to address the unsafe condition on these products.
