## Abstract

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.
