## Summary

We propose to supersede Airworthiness Directive (AD) 2016-11- 02, which applies to all Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes; 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. AD 2016-11-02 requires repetitive inspections of the upper and lower engine pylons for protruding, loose, or missing fasteners; and repair if necessary. Since we issued AD 2016-11-02, we have determined that a terminating action is necessary to address the unsafe condition. This proposed AD would continue to require the repetitive inspections of the upper and lower engine pylons for protruding, loose, or missing fasteners; and repair if necessary. This proposed AD would also require replacement of affected fasteners, which terminates the inspections. We are proposing this AD to address the unsafe condition on these products.
