Abstract
We are superseding Airworthiness Directive (AD) 2015-17-04, which applied to certain Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet Series 705), and Model CL-600-2D24 (Regional Jet Series 900) airplanes. AD 2015-17-04 required replacement of left and right fixed control rods and lever assemblies of the elevator control system. This AD adds a detailed visual inspection of the key washers and self-locking nuts of the elevator control linkages and corrective actions if necessary. This AD was prompted by reports of a disconnect between the elevator lever and control rod and a report indicating that certain revisions of the service information were missing instructions for proper installation of certain key washers. We are issuing this AD to address the unsafe condition on these products.
