ACTION: Final rule. –––––––––––––––––––––––––––––––––– SUMMARY: The FAA is revising an existing airworthiness directive (AD) that applies to certain Bombardier Model CL-600-2C10 (Regional Jet series 700 & 701) series airplanes and Model CL- 600-2D24 (Regional Jet series 900) series airplanes. That AD currently requires revising the Airworthiness Limitations section of the Instructions of Continued Airworthiness by incorporating new repetitive inspections and an optional terminating action for the repetitive inspections, and repairing any crack. This new AD clarifies the applicability of the existing AD. This AD results from reports of hydraulic pressure loss in either the number 1 or number 2 hydraulic system due to breakage or leakage of hydraulic lines in the aft equipment bay and reports of cracks on the aft pressure bulkhead web around the feed-through holes. We are issuing this AD to prevent loss of hydraulic pressure, which could result in reduced controllability of the airplane, and to detect and correct cracks on the aft pressure bulkhead web, which could result in reduced structural integrity of the aft pressure bulkhead. DATES: This AD is effective December 3, 2008. On July 27, 2005 (70 FR 35987, June 22, 2005), the Director of the Federal Register approved the incorporation by reference of Bombardier CRJ 700/900 Series Temporary Revision MRM2-129, dated June 1, 2004. ADDRESSES: For service information identified in this AD, contact Bombardier, Inc., Canadair, Aerospace Group, P.O. Box 6087, Station Centre-ville, Montreal, Quebec H3C 3G9, Canada. 2 Examining the AD Docket You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this AD, the regulatory evaluation, any comments received, and other information. The address for the Docket Office (telephone 800-647-5527) is the Document Management Facility, U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC 20590. FOR FURTHER INFORMATION CONTACT: Pong Lee, Aerospace Engineer, Airframe and Propulsion Branch, ANE-171, FAA, New York Aircraft Certification Office, 1600 Stewart Avenue, Suite 410, Westbury, New York 11590; telephone (516) 228-7324; fax (516) 794-5531. SUPPLEMENTARY INFORMATION: Discussion The FAA proposed to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) with an airworthiness directive (AD) to revise AD 2005-13-02, amendment 39-14138 (70 FR 35987, June 22, 2005). The existing AD applies to certain Bombardier Model CL-600-2C10 (Regional Jet series 700 & 701) series airplanes and Model CL-600-2D24 (Regional Jet series 900) series airplanes. The proposed AD was published in the Federal Register on May 19, 2008 (73 FR 28754) to continue to revise the Airworthiness Limitations section of the Instructions of Continued Airworthiness by incorporating new repetitive inspections and an optional terminating action for the repetitive inspections, and repairing any crack. The proposed AD also clarifies the applicability of the existing AD. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. Request To Withdraw NPRM Comair requests that the NPRM be withdrawn. Comair states that the minor editorial correction to the Applicability section of the NPRM should not warrant a revised or new directive, and that the revised AD will not increase the airworthiness of any airplane. Comair also states that a review of the airplane log will indicate which service bulletins have been incorporated by Bombardier, on a limited basis, before delivery to a customer. We do not agree with Comair to withdraw the NPRM. When a previously issued AD is changed, we issue a correction, revision, or supersedure AD, depending on the nature of the material being changed. In the case of this AD, a revision AD is the appropriate means to clarify the Applicability section of AD 2005-13-02. We have determined that issuance of this AD is necessary because Bombardier does not incorporate service bulletins in production and operators may misinterpret which affected airplanes are subject to the requirements of this AD. Requests To Revise the Applicability Section Comair notes that Bombardier Service Bulletin 670BA-29-008 is currently at Revision B, dated August 28, 2007. Paragraph (c) of the NPRM (i.e., Applicability section) refers to the initial issue, dated March 12, 2004; and Revision A, dated May 5, 2004; of that service bulletin.
