Airworthiness Directive · Amendment 39-17915 · Landing gear
Bombardier, Inc. Airplanes
This AD applies to Bombardier, Inc. airplanes, certificated in any category, as identified in paragraphs (c)(1) through (c)(4) of this AD.
(1) Model CL-600-1A11 (CL-600) airplanes, serial numbers 1004 through 1085 inclusive.
(2) Model CL-600-2A12 (CL-601) airplanes, serial numbers 3001 through 3066 inclusive;
(3) Model CL-600-2B16 (CL-601-3A and CL-601-3R Variants) airplanes, serial numbers 5001 through 5194 inclusive.
(4) Model CL-600-2B16 (CL-604 Variant) airplanes, serial numbers 5301 through 5573 inclusive, 5579, and 5595.
(5) This AD requires revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (r) of this AD. The request should include a description of changes to the required actions that will ensure the continued damage tolerance of the affected structure.
We are superseding Airworthiness Directive (AD) 2005-15-04 for certain Bombardier, Inc. Model CL-600-1A11 (CL-600), CL-600-2A12 (CL- 601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. AD 2005-15-04 required operators to assign serial numbers or part numbers to certain landing gear parts; establish the number of landings on the parts, if necessary; and revise the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA) to reflect the new life limits of the landing gear parts. This new AD adds airplanes to the applicability, requires operators to assign serial numbers or part numbers to certain additional landing gear parts to establish the number of landings on the parts if necessary, and requires operators to record in all required airplane technical records and manuals the new part numbers, serial numbers, and landings assigned to these parts. This AD was 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.
This paragraph restates the actions required by paragraph (f) of AD 2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005), with revised affected airplanes. Except for Model CL-600-2B16 airplanes having S/Ns 5514 through 5595 inclusive: At the applicable compliance time specified in paragraph (g)(1), (g)(2), or (g)(3) of this AD, add serial numbers and part numbers, as applicable, to the parts identified in the applicable service bulletin specified in paragraph (g)(1), (g)(2), or (g)(3) of this AD. Do all actions in accordance with the applicable service bulletin specified in paragraph (g)(1), (g)(2), or (g)(3) of this AD.
(1) 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 “five years for the parts listed in Part A”: Within 60 months after August 30, 2005 (the effective date of AD 2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005)).
(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 August 30, 2005 (the effective date of AD 2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005)).
(3) For parts identified in 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 August 30, 2005 (the effective date of AD 2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005)).
Note 1 to paragraph (g) of this AD: The Bombardier service bulletins identified in paragraphs (g)(1), (g)(2), and (g)(3) of this AD refer to the Messier-Dowty service bulletins identified in table 1 to paragraph (g) of this AD as additional sources of guidance 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.

This paragraph restates the limitations specified in paragraph (i) of AD 2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005), with revised affected airplanes. Except for Model CL-600-2B16 airplanes having serial numbers 5514 through 5595 inclusive: As of August 30, 2005 (the effective date of AD 2005-15-04), 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 (g) of this AD; and has had the number of landings established in accordance with paragraph (h) of this AD.
