AD 2013-24-02 Airworthiness Directives; Bombardier, Inc. Airplanes

This AD applies to Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category, serial numbers 7003 and subsequent.

You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.

At the applicable time specified in paragraphs (g)(1) through (g)(6) of this AD, do a detailed or eddy current inspection for cracking and damage (i.e., corrosion or cracking) of both pilot-side rudder pedal tubes having part number (P/N) 600-90204-3, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 601R-27-162, including Appendix A, dated April 5, 2013. (1) For airplanes that have accumulated less than 20,000 total flight cycles as of the effective date of this AD: Do the inspection before the accumulation of 23,000 total flight cycles. (2) For airplanes that have accumulated 20,000 total flight cycles or more, but less than 25,000 total flight cycles as of the effective date of this AD: Do the inspection within 3,000 flight cycles after the effective date of this AD, but not to exceed 26,300 total flight cycles. (3) For airplanes that have accumulated 25,000 total flight cycles or more, but less than 30,000 total flight cycles as of the effective date of this AD: Do the inspection within 1,300 flight cycles after the effective date of this AD, but not to exceed 30,800 total flight cycles. (4) For airplanes that have accumulated 30,000 total flight cycles or more, but less than 33,000 total flight cycles as of the effective date of this AD: Do the inspection within 800 flight cycles after the effective date of this AD, but not to exceed 33,500 total flight cycles. (5) For airplanes that have accumulated 33,000 total flight cycles or more, but less than 37,000 total flight cycles as of the effective date of this AD: Do the inspection within 500 flight cycles after the effective of this AD, but not to exceed 37,300 total flight cycles. (6) For airplanes that have accumulated 37,000 total flight cycles or more as of the effective date of this AD: Do the inspection within 300 flight cycles after the effective date of this AD.

This AD was prompted by reports of fractured rudder pedal tubes installed on the pilot-side rudder bar assembly. We are issuing this AD to detect and correct cracking of both pilot-side rudder pedal tubes, which could result in loss of pilot rudder pedal input causing reduced yaw controllability or a runway excursion.

None.
