## Summary

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-215-6B11 (CL-215T Variant), and CL- 215-6B11 (CL-415 Variant) airplanes. This proposed AD was prompted by several reports indicating that shorter nacelle strut bushings were inadvertently installed on certain airplanes. This proposed AD would require a general visual inspection of the left and right nacelle upper strut bushings; installation of the bolts and preload indicating (PLI) washers, if necessary; and replacement of the bushing or repair of the bushing installation, if necessary. We are proposing this AD to detect and correct inadequate nacelle strut bushings, which provide insufficient engagement in the strut fork end, and could deform under the bearing load and lead to the failure of the joint.
