Applicability*9

This AD applies to Bombardier, Inc. airplanes, certificated in any category, identified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD. (1) Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, serial numbers 10002 through 10335 inclusive. (2) Bombardier, Inc. Model CL-600-2D15 (Regional Jet Series 705) airplanes, and Bombardier, Inc. Model CL-600-2D24 (Regional Jet Series 900) airplanes, serial numbers 15001 through 15293 inclusive. (3) Bombardier, Inc. Model CL-600-2E25 (Regional Jet Series 1000) airplanes, serial numbers 19002 through 19036 inclusive.

Compliance

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

Required actions

Within 6,000 flight hours or 30 months, whichever occurs first, after the effective date of this AD: Remove and replace the locking plate having part number (P/N) CC670-12076-1 with an anti-migration assembly having P/N CC670-12370-1, on both the left and right number 3 slats, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 670BA-27-066, dated June 10, 2013.

Unsafe condition

This 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. We are issuing this AD to prevent failure of the eccentric pins at the slat track attachment, and slat panels consequently disconnecting from the wing, leading to the loss of the airplane.

Affected ADs

None.
