Airworthiness Directives; Bombardier, Inc., Airplanes

FAA / Federal Register · 2019-04411

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This proposed AD was prompted by reports that certain aft fuselage fittings are susceptible to cracking because they were not manufactured correctly. This proposed AD would require replacement of those fittings with correctly manufactured parts, an eddy current inspection of certain fastener holes for cracking, and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.
