## Summary

We propose to supersede Airworthiness Directive (AD) 2015-17- 04, which applies 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 requires replacement of left and right fixed control rods and lever assemblies of the elevator control system. Since we issued AD 2015-17-04, we have received a report indicating that certain revisions of the service information were missing instructions. This proposed AD would require a detailed visual inspection of the key washers and self- locking nuts of the elevator control linkages and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.
