Airworthiness Directive · Amendment 39-15758 · Landing gear
Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
Superseded. A later AD replaced this one: AD 2019-08-11. Comply with the one in force.
This AD applies to all Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category.
Note 1: This AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish the inspections 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 (g)(1) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane. The FAA has provided guidance for this determination in Advisory Circular (AC) 25-1529-1A.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions.
(1) Within 30 days after the effective date of this AD, revise the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate the Airworthiness Limitation (AWL) No. 57-21-161, as identified in Bombardier Temporary Revision 2B-2136, dated May 1, 2008, to the Bombardier CL-600-2B19 Maintenance Requirements Manual, Part 2, Appendix B—Airworthiness Limitations. The initial compliance time for the task starts from the applicable time specified in Table 1 or Table 2 of this AD, as applicable. Repeat the inspection thereafter at the applicable interval specified in Bombardier Temporary Revision 2B-2136, dated May 1, 2008.
| If the airplane has accumulated (as of the effective date of this AD)— | Then phase in the initial inspection— |
|---|---|
| 23,500 total flight cycles or fewer | Prior to the accumulation of 25,000 total flight cycles. |
| 23,501 to 25,000 total flight cycles | Prior to the accumulation of 26,000 total flight cycles, or within 1,500 flight cycles after the effective date of this AD, whichever occurs first. |
| 25,001 to 26,000 total flight cycles | Prior to the accumulation of 26,500 total flight cycles, or within 1,000 flight cycles after the effective date of this AD, whichever occurs first. |
| 26,001 or more total flight cycles | Within 500 flight cycles after the effective date of this AD. |
| If the airplane has accumulated (as of the effective date of this AD)— | Then phase in the initial inspection— |
|---|---|
| 15,667 total flight cycles or fewer | Prior to the accumulation of 16,667 total flight cycles. |
| 15,668 to 16,667 total flight cycles | Prior to the accumulation of 17,333 total flight cycles, or within 1,000 flight cycles after the effective date of this AD, whichever occurs first. |
| 16,668 to 17,333 total flight cycles | Prior to the accumulation of 17,666 total flight cycles, or within 666 flight cycles after the effective date of this AD, whichever occurs first. |
| 17,334 or more total flight cycles | Within 333 flight cycles after the effective date of this AD. |
(2) After accomplishing the actions specified in paragraph (f)(1) of this AD, no alternative inspections or inspection intervals may be used unless the inspection or inspection interval is approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (g)(1) of this AD.
Note 2: This AD differs from the MCAI and/or service information as follows: No differences.
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.
