## Summary

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. This proposed AD was prompted by a determination that no instructions for continued airworthiness exist for the nose landing gear (NLG) alternate extension actuator of the NLG alternate release system. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate a new airworthiness limitation task for the NLG alternate extension actuator. We are proposing this AD to prevent failure of the NLG alternate release system and, if the normal NLG extension system also fails, failure of the NLG to extend, and consequent damage to the airplane and injury to occupants.
