Docket No. FAA-2007-0414
Amendment 39-15413
AD 2008-06-01

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on January 4, 2008 (73 FR 830). (A correction of the rule was published in the Federal Register on January 31, 2008 (73 FR 5767).) That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:
We revised paragraph (f)(1) of this AD to add a reference to “Transport Canada Civil Aviation (TCCA) (or its delegated agent)” for approval of a particular document. We also revised paragraph (f)(2) of this AD to specify that no alternative inspections or inspection intervals may be used unless they are part of a later approved revision of Section 3, “Fuel System Limitations,” of Part 2 of Bombardier CL-600-2C10, CL-600-2D15, and CL-600-2D24 Maintenance Requirements Manual CSP Start Printed Page 13099B-053, Revision 9, dated July 20, 2007, or unless they are approved as an alternative method of compliance (AMOC). Inclusion of this paragraph in the AD is intended to ensure that the AD-mandated airworthiness limitations changes are treated the same as the airworthiness limitations issued with the original type certificate.
We estimate that this AD will affect about 289 products of U.S. registry. We also estimate that it will take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of the AD on U.S. operators to be $23,120, or $80 per product.
2008-06-01 Bombardier, Inc. (Formerly Canadair): Amendment 39-15413. Docket No. FAA-2007-0414; Directorate Identifier 2007-NM-340-AD.
The assessment showed that supplemental maintenance tasks [for the fuel tank wiring harness installation, and the hydraulic system No. 3 temperature transducer, among other items] are required to prevent potential ignition sources inside the fuel system, which could result in a fuel tank explosion. Revision has been made to Canadair Regional Jet Models CL-600-2C10, CL-600-2D15 and CL-600-2D24 Maintenance Requirements Manual, CSP B-053, Part 2, Section 3 “Fuel Start Printed Page 13100System Limitations” to introduce the required maintenance tasks.
(1) Within 60 days after the effective date of this AD, or on or before December 16, 2008, whichever occurs first, revise the ALS of the Instructions for Continued Airworthiness to incorporate the inspection requirements 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 (“the MRM”). 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, the initial compliance times start from the later of the times specified in paragraphs (f)(1)(i) and (f)(1)(ii) of this AD, and the repetitive inspections must be accomplished thereafter at the interval specified in the MRM, except as provided by paragraphs (f)(1) and (g)(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) 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 interval is part of a later revision of the 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, that is approved by the Manager, New York ACO, FAA, or TCCA (or its delegated agent); or unless the inspection or interval is approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (g)(1) of this AD.
(h) Refer to MCAI Canadian Airworthiness Directive CF-2007-28, dated November 22, 2007; and 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; for related information.
(i) You must use 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, to do the actions required by this AD, unless the AD specifies otherwise.
(3) You may review copies at the FAA, Transport Airplane Directorate, 1601 Lind Avenue SW., Renton, Washington; or at the National Archives and Records Administration (NARA).
