ACTION: Final rule. –––––––––––––––––––––––––––––––––– SUMMARY: We are correcting the address, telephone, and fax information for the reporting requirement in Airworthiness Directive (AD) 2009-08-05, which applies to certain Liberty Aerospace Incorporated Model XL-2 airplanes. AD 2009-08-05 currently requires repetitively inspecting the exhaust muffler for cracks, replacing the exhaust muffler when cracks are found, and reporting the results of the inspections to the FAA. Since AD 2009-08-05 became effective, the FAA's Atlanta Aircraft Certification Office (ACO) moved, which has caused the office personnel problems in receiving fax and mailed copies of the inspection result reports. This document corrects the mailing address, telephone number, and fax information of the Atlanta ACO. DATES: This final rule is effective April 19, 2010. The compliance date of this AD is April 20, 2009, which is the same as the effective date of AD 2009-08-05. As of April 20, 2009 (74 FR 16117, April 9, 2009), the Director of the Federal Register approved the incorporation by reference of Liberty Aerospace, Inc. Service Document Critical Service Bulletin (CSB) CSB-09-001, Revision Level B, Revised on March 18, 2009. ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at 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: –Corey Spiegel, Aerospace Engineer, Atlanta Aircraft Certification Office, 1701 Columbia Avenue, College Park, Georgia 30337; telephone: (404) 474-5574; facsimile: (404) 474-5606; e-mail: corey.spiegel@faa.gov; or 2 –Cindy Lorenzen, Aerospace Engineer, Atlanta Aircraft Certification Office, 1701 Columbia Avenue, College Park, Georgia 30337; telephone: (404) 474-5524; facsimile: (404) 474-5606; e-mail: cindy.lorenzen@faa.gov. SUPPLEMENTARY INFORMATION: Discussion On April 3, 2009, we issued AD 2009-08-05, Amendment 39-15878 (74 FR 16117, April 9, 2009), to require repetitively inspecting the exhaust muffler for cracks, replacing the exhaust muffler when cracks are found, and reporting the results of the inspections to the FAA. Since AD 2009-08-05 became effective, the FAA's Atlanta Aircraft Certification Office (ACO) moved, which has caused the office personnel problems in receiving fax and mailed copies of the inspection result reports. Consequently, the FAA sees a need to correct the mailing address, telephone number, and fax information of the Atlanta ACO in AD 2009-08-05 to assure that the inspection results are received and reviewed to help assure the continued operational safety of the affected airplanes. Thus, the FAA is revising the AD to incorporate the language discussed above and to add the amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 39.13). Since this action only corrects the address, telephone number, and fax information for the reporting requirement and does not require any additional actions over that originally required by AD 2009-08-05, it has no adverse economic impact and imposes no additional burden on any person than was already required. Therefore, the FAA has determined that prior notice and opportunity for public comment are unnecessary. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39–AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by removing Airworthiness Directive (AD) 2009-08-05, Amendment 39-15878 (74 FR 16117, April 9, 2009), and adding the following new AD:
