We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2008-0643; Directorate Identifier 2008-NM-094-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD based on those comments.
On February 28, 2008, we issued AD 2008-06-02, Amendment 39-15414 (73 FR 13100, March 12, 2008). That AD required actions intended to address an unsafe condition on the products listed above.
Since we issued AD 2008-06-02, we have determined that, for certain airplanes, the initial compliance times for doing the tasks specified in paragraph (f)(1) of that AD must be reduced. AD 2008-06-02 resulted from Canadian Airworthiness Directive CF-2007-29, dated November 22, 2007 (referred to after this as “the MCAI”).
The MCAI does not provide an initial compliance time for doing the tasks for certain airplanes. In AD 2008-06-02, for those airplanes, we required an initial compliance time that started from the effective date of the AD, or the date of issuance of the original Canadian standard airworthiness certificate or the date of issuance of the original Canadian export certificate of airworthiness, whichever occurs later. Although the initial compliance time for doing the tasks is unstated in the MCAI, we have determined that the intent of the MCAI is for the initial compliance time to start from the initial delivery date of the airplane in order to address the identified unsafe condition in a timely manner.
This proposed AD would require reduced thresholds for the initial compliance times for the airplanes and tasks that are not identified in paragraphs (f)(2), (f)(3), and (f)(4) of AD 2008-06-02. You may obtain further information by examining the MCAI in the AD docket.
2. The FAA amends § 39.13 by removing Amendment 39-15414 (73 FR 13100, March 12, 2008) and adding the following new AD:
Bombardier, Inc. (Formerly Canadair): Docket No. FAA-2008-0643; Directorate Identifier 2008-NM-094-AD.
(b) The proposed AD supersedes AD 2008-06-02, Amendment 39-15414. Start Printed Page 35097
(1) Within 60 days after April 16, 2008 (the effective date of AD 2008-06-02), revise the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate the inspection and maintenance requirements, as applicable, in Canadair Regional Jet Model CL-600-2B19 Airworthiness Requirements in the Maintenance Requirements Manual, CSP A-053, Part 2, Appendix D, “Fuel System Limitations,” Revision 7, dated May 10, 2007 (“the MRM”), task numbers 28-11-00-601, 28-11-00-602, 28-11-00-603, 28-11-00-604, 29-33-01-601, and 29-33-01-602. Except as required by paragraph (g)(1) of this AD, for those task numbers, the initial compliance times start at the applicable time specified in paragraphs (f)(2), (f)(3), and (f)(4) of this AD, and the repetitive inspections must be accomplished thereafter at the interval specified in the MRM, except as provided by paragraphs (f)(5) and (h)(1) of this AD. Accomplishing the revision in accordance with a later revision of the MRM is an acceptable method of compliance if the revision is approved by the Manager, New York Aircraft Certification Office (ACO), FAA), or Transport Canada Civil Aviation (TCCA) (or its delegated agent).
(2) For airplanes having more than 15,000 flight hours as of April 16, 2008, the initial compliance time for Tasks 28-11-00-601, 28-11-00-602, 28-11-00-603, and 28-11-00-604 is within 5,000 flight hours after April 16, 2008. Thereafter, these tasks must be accomplished within the repetitive interval specified in Canadair Regional Jet Model CL-600-2B19, Airworthiness Requirements in the Maintenance Requirements Manual, CSP A-053, Part 2, Appendix D, “Fuel System Limitations,” Revision 7, dated May 10, 2007.
(3) For Task 29-33-01-601, the initial compliance time is within 5,000 flight hours after April 16, 2008. Thereafter, task 29-33-01-601 must be accomplished within the repetitive interval specified in Canadair Regional Jet Model CL-600-2B19, Airworthiness Requirements in the Maintenance Requirements Manual, CSP A-053, Part 2, Appendix D, “Fuel System Limitations,” Revision 7, dated May 10, 2007.
(4) For airplanes having more than 27,500 flight hours as of April 16, 2008, the initial compliance time for Task 29-33-01-602 is within 2,500 flight hours after April 16, 2008. Thereafter, this task must be accomplished within the repetitive interval specified in Canadair Regional Jet Model CL-600-2B19, Airworthiness Requirements in the Maintenance Requirements Manual, CSP A-053, Part 2, Appendix D, “Fuel System Limitations,” Revision 7, dated May 10, 2007.
(5) After accomplishing the actions specified in paragraphs (f)(1), (f)(2), (f)(3), and (f)(4) of this AD, no alternative inspections/limitation tasks or inspection/limitation task intervals may be used unless the inspections/limitation tasks or inspection/limitation task intervals are part of a later approved revision of Canadair Regional Jet Model CL-600-2B19, Airworthiness Requirements in the Maintenance Requirements Manual, CSP A-053, Part 2, Appendix D, “Fuel System Limitations,” Revision 7, dated May 10, 2007, that is approved by the Manager, New York ACO, FAA, or TCCA (or its delegated agent); or 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.
(1) At the times specified in paragraphs (g)(1)(i) and (g)(1)(ii) of this AD, as applicable, do the initial inspection for Tasks 28-11-00-601, 28-11-00-602, 28-11-00-603, 28-11-00-604, and 29-33-01-602, as applicable, in the MRM, and thereafter repeat the inspection at the applicable interval specified in the MRM, except as provided by (g)(2) of this AD.
(i) For airplanes not identified in paragraph (f)(2) of this AD, the initial compliance time for Tasks 28-11-00-601, 28-11-00-602, 28-11-00-603, and 28-11-00-604 is before the accumulation of 20,000 total flight hours, or within 5,000 flight hours after the effective date of this AD, whichever occurs later.
(ii) For airplanes not identified in paragraph (f)(4) of this AD, the initial compliance time for Task 29-33-01-602 is before the accumulation of 30,000 total flight hours, or within 2,500 flight hours after the effective date of this AD, whichever occurs later.
(2) After accomplishing the actions specified in paragraphs (g)(1)of this AD, no alternative inspections/limitation tasks or inspection/limitation task intervals may be used unless the inspections/limitation tasks or inspection/limitation task intervals are part of a later approved revision of Canadair Regional Jet Model CL-600-2B19, Airworthiness Requirements in the Maintenance Requirements Manual, CSP A-053, Part 2, Appendix D, “Fuel System Limitations,” Revision 7, dated May 10, 2007, that is approved by the Manager, New York ACO, FAA, or TCCA (or its delegated agent); or 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.
(2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required Start Printed Page 35098to assure the product is airworthy before it is returned to service.
(i) Refer to MCAI Canadian Airworthiness Directive CF-2007-29, dated November 22, 2007, and Canadair Regional Jet Model CL-600-2B19, Airworthiness Requirements in the Maintenance Requirements Manual, CSP A-053, Part 2, Appendix D, “Fuel System Limitations,” Revision 7, dated May 10, 2007; for related information.
