Airworthiness Directive · Amendment 39-19036 · Wings
Bombardier, Inc., Airplanes
This AD applies to the airplanes specified in paragraphs (c)(1) through (c)(3) of this AD, certificated in any category.
(1) Bombardier, Inc. Model CL-600-1A11 (CL-600) airplanes, serial numbers 1004 through 1085 inclusive.
(2) Bombardier, Inc. Model CL-600-2A12 (CL-601 Variant) airplanes, serial numbers 3001 through 3066 inclusive.
(3) Bombardier, Inc. Model CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes, serial numbers 5001 through 5194 inclusive; serial numbers 5301 through 5665 inclusive, and serial numbers 5701 through 5851 inclusive.
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601 Variant), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. This AD was prompted by a new life limitation that has been introduced for the side brace fitting shaft and side brace-to-airplane fitting pin of the main landing gear (MLG). This AD requires revising the maintenance or inspection program. This AD also requires an inspection to identify the serial number, to serialize, and to record the accumulated life of the side brace fitting shaft of the MLG. We are issuing this AD to address the unsafe condition on these products.
Within 30 days after the effective date of this AD, revise the maintenance or inspection program, as applicable, by incorporating the life limits for the side brace fitting shaft and side brace-to-airplane fitting pin of the MLG, as applicable, identified in table 1 to paragraph (g) of this AD. The initial compliance time for accomplishing the replacement is at the applicable time in the Bombardier Time Limits/Maintenance Checks (TLMC) Manual revisions specified in table 1 to paragraph (g) of this AD, or within 30 days after the effective date of this AD, whichever occurs later.

Although the service information identified in paragraphs (h)(1) through (h)(4) of this AD specifies to submit certain information to the manufacturer, this AD does not include that requirement.
After the maintenance or inspection program has been revised, as applicable, as required by paragraph (g) of this AD, no alternative actions (e.g., inspections) or intervals may be used unless the actions or intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (k)(1) of this AD.
