Airworthiness Directive · Amendment 39-16112 · Engine controls
Bombardier Model CL-600-2A12 (CL-601) and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) Airplanes
This AD applies to all Bombardier Model CL-600-2A12 (CL-601) and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) 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.
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 of the Instructions for Continued Airworthiness by incorporating the applicable task in the TR listed in Table 1 of this AD.
| For Bombardier model— | Use Canadair Challenger Temporary Revision— | Dated— | To the Airworthiness Limitations section of— |
|---|---|---|---|
| CL-600-2A12 (CL-601) airplanes | 5-236 | July 25, 2008 | Section 5-10-30 of Chapter 5 of the Canadair Challenger Time Limits/Maintenance Checks, PSP 601-5. |
| CL-600-2B16 (CL-601-3A, and CL-601-3R) airplanes | 5-236 | March 22, 2007 | Section 5-10-30 of Chapter 5 of the Canadair Challenger Time Limits/Maintenance Checks, PSP 601A-5. |

Thereafter, except as provided by paragraph (g)(1) of this AD, no alternative TLMC task intervals may be used.
(3) When information in a TR specified in paragraph (f)(1) has been included in the general revisions of the applicable Airworthiness Limitations section, the TR may be removed from that Airworthiness Limitations section of the Instruction for Continued Airworthiness.
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.
