## Summary

We propose to adopt a new airworthiness directive (AD) for certain 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. This proposed AD was prompted by a determination that for certain slat system jam- disconnect failure cases, the resulting slat skew could lead to failure of the eccentric pin at the slat track attachment. If the pin migrates out of the attachment lugs, this could cause certain slat panels to disconnect from the wing. This proposed AD would require replacing certain locking plates with certain anti-migration assemblies on certain left and right wing slats. We are proposing this AD to prevent failure of the eccentric pins at the slat track attachment, and consequent slat panels disconnecting from the wing, leading to the loss of the airplane.
