Applicability*9

This AD applies to the airplanes, certificated in any category, identified in paragraphs (c)(1) and (c)(2) of this AD. (1) Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, serial numbers (S/N) 10002 through 10337 inclusive. (2) Bombardier, Inc. Model CL-600-2D15 (Regional Jet Series 705) and CL-600-2D24 (Regional Jet Series 900) airplanes, S/Ns 15001 through 15298 inclusive.

Compliance

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

Required actions

Within 9,200 flight hours or 5 years, whichever occurs first, after the effective date of this AD: Replace the left and right fixed control rods and lever assemblies of the elevator control system with newly designed control rods and lever assemblies, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 670BA-27-062, Revision C, dated February 13, 2015.

Unsafe condition

This AD was prompted by reports of a disconnect between the elevator lever and control rod. We are issuing this AD to prevent a disconnect between the elevator lever and control rod, which could lead to un-commanded elevator movement of the associated control surface, a large difference between the position of the left and the right elevator control surfaces, and consequent reduced controllability of the airplane and degradation of the structural integrity of the horizontal stabilizer.

Affected ADs

None.
