## Summary

We propose to adopt a new airworthiness directive (AD) for all 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 new or more restrictive airworthiness limitations are necessary for operational checks of the landing gear alternate extension system (AES). This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new and more restrictive airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.
