Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Within 3 months after the effective date of this AD: Do a general visual inspection to determine the part number of the left and right nacelle upper strut bushings, in accordance with the Accomplishment Instructions of Bombardier Alert Service Bulletin 215-A3173, dated April 11, 2012 (for Model CL-215-6B11 (CL-215T Variant) airplanes); or Bombardier Alert Service Bulletin 215-A4453, dated April 10, 2012 (for Model CL-215-6B11 (CL-415 Variant) airplanes). (1) If any bushing with part number (P/N) 85410265-103 is installed: Before further flight, install the bolts and preload indicating (PLI) washers, in accordance with paragraph 2.G. of the Accomplishment Instructions of Bombardier Alert Service Bulletin 215-A3173, dated April 11, 2012 (for Model CL-215-6B11 (CL-215T Variant) airplanes); or Bombardier Alert Service Bulletin 215-A4453, dated April 10, 2012 (for Model CL-215-6B11 (CL-415 Variant) airplanes). (2) If any bushing with P/N 85410265-105 is installed in either the left or right nacelle: Do the actions in paragraph (h) of this AD.

Unsafe condition

This AD was prompted by several reports indicating that shorter nacelle strut bushings were inadvertently installed on certain airplanes. We are issuing 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.

Affected ADs

None.
