The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-1A11 (CL-600), Model CL-600-2A12 (CL- 601), and Model CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) airplanes. This AD requires operators to assign serial numbers or part numbers to certain landing gear parts and to establish the number of landings on the parts, if necessary. This AD also requires operators to revise the Airworthiness Limitations section of the Instructions for Continued Airworthiness to reflect the new life limits of the landing gear parts. This AD is prompted by reports that landing gear parts that have safe-life limits but do not have serial numbers or part numbers can be removed from one landing gear and re-installed on another, making tracking difficult. We are issuing this AD to prevent life-limited landing gear parts from being used beyond their safe-life limits, which could lead to collapse of the landing gear.
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 compliance time specified in paragraph (f)(1), (f)(2), or (f)(3) of this AD: Add serial numbers and part numbers, as applicable, to the parts identified in the service bulletins. Do all actions in accordance with the applicable service bulletin.
(1) For parts identified in the Bombardier Service Bulletin 600-0710, Revision 01, dated December 15, 2003; and Bombardier Service Bulletin 601-0546, Revision 01, dated December 15, 2003; as having a compliance time of “five years for the parts listed in Part A': Within 60 months after the effective date of this AD.
(2) For parts identified in Bombardier Service Bulletin 600-0710, Revision 01, dated December 15, 2003; and Bombardier Service Bulletin 601-0546, Revision 01, dated December 15, 2003; as having a compliance time of “ten years for the parts listed in Part B': Within 120 months after the effective date of this AD.
(3) For parts identified in the Bombardier Service Bulletin 604-32-014, dated May 31, 2002, as having a compliance time of “no later than a calendar time of 8 years': Within 96 months after the effective date of this AD.
Note 1: The Bombardier service bulletins refer to the Messier-Dowty service bulletins in Table 2 of this AD as additional sources of service information for adding part numbers or serial numbers by vibro-peening the numbers on main landing gear (MLG) and nose landing gear (NLG) components that do not have them; and for determining the number of landings for parts without a part number or serial number on which the time since new (TSN) and cycles since new (CSN) have not been tracked.

At the applicable time specified in paragraph (f) of this AD: If a component does not have a serial number and the CSN or TSN were not tracked, use the formula in the applicable Messier-Dowty service bulletin in Table 2 of this AD to establish the number of landings (TSN or CSN), and record the newly calculated TSN or CSN in the aircraft log books.
Within 30 days after the effective date of this AD, revise the ALS of the applicable Instructions for Continued Airworthiness to reflect the new life limits of the landing gear parts by inserting copies of the Canadair temporary revisions (TR) in Table 3 of this AD into the ALS of the applicable Canadair Time-Limits/Maintenance Check Manual. When the contents of the TRs are included in the general revisions of the ALS, these TRs may be removed provided the relevant information in the ALS is identical to that in the TRs.

(i) As of the effective date of this AD, no person may install on any airplane a landing gear part, unless it has had the applicable part number or serial number added in accordance with paragraph (f) of this AD; and had the number of landings established in accordance with paragraph (g) of this AD.
Although the service bulletins identified in paragraph (f) of this AD specify that operators submit incorporation notices to Bombardier after each new part number or serial number and landings assigned to these parts is added, this AD does not include that action.
Actions done before the effective date of this AD in accordance with Bombardier Service Bulletin 601-0546, dated May 31, 2002; and Bombardier Service Bulletin 600-0710, dated May 31, 2002; are acceptable for compliance with the corresponding actions specified in this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
