Airworthiness Directive · Amendment 39-15699 · Fuel
Bombardier Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) Airplanes
This AD applies to all Bombardier Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes, certificated in any category, all serial numbers.
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 (h)(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 superseding an existing 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, within 60 days after April 16, 2008 (the effective date of AD 2008-06-01), revise the ALS of the Instructions for Continued Airworthiness to incorporate the inspection requirements in Section 3, “Fuel System Limitations,” of Part 2 of Bombardier CL-600-2C10, CL-600-2D15, and CL-600-2D24 Maintenance Requirements Manual CSP B-053, Revision 9, dated July 20, 2007; or Revision 10, dated March 20, 2008.
Unless already done, do the following actions.
(1) For task numbers 24-90-00-601, 24-90-00-602, 28-00-00-601, 28-11-23-601, 28-11-23-602, 28-12-13-601, 29-30-00-601, and 29-30-00-602 identified in Section 3, “Fuel System Limitations,” of Part 2 of Bombardier CL-600-2C10, CL-600-2D15, and CL-600-2D24 Maintenance Requirements Manual CSP B-053, Revision 9, dated July 20, 2007; or Revision 10, dated March 20, 2008: The initial compliance times start at the later of the applicable “Threshold” and “Grace Period” times specified in Table 1 of this AD, and the repetitive limitation tasks must be accomplished thereafter at the applicable interval specified in Revision 9 or Revision 10 of the Bombardier CL-600-2C10, CL-600-2D15, and CL-600-2D24 Maintenance Requirements Manual CSP B-053, except as provided by paragraph (g)(2) and (h)(1) of this AD.
| Compliance time (whichever occurs later) | Threshold | Grace period |
|---|---|---|
| Tasks with limiting intervals of 8,000 flight hours | Before the accumulation of 8,000 total flight hours | Within 2,000 flight hours after the effective date of this AD. |
| Tasks with limiting intervals of 20,000 flight hours | Before the accumulation of 20,000 total flight hours | Within 6,000 flight hours after the effective date of this AD. |
| Tasks with limiting intervals of 30,000 flight hours | Before the accumulation of 30,000 total flight hours | Within 6,000 flight hours after the effective date of this AD. |
(2) After accomplishing the actions specified in paragraph (g)(1) of this AD, no alternative inspections/limitation tasks or inspection/limitation task intervals may be used unless the inspection/limitation task or inspection/limitation task interval is approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (h)(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.
