## Summary

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This proposed AD was prompted by reports of failures of the landing gear alternate-extension system. This proposed AD would require replacement of certain nose landing gear and main landing gear electro- mechanical actuators. We are proposing this AD to address the unsafe condition on these products.
