Airworthiness Directives; Liberty Aerospace Incorporated Model XL-2 Airplanes
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.

Liberty Aerospace Incorporated Model XL-2 Airplanes
Requires you to repetitively inspect the exhaust muffler for cracks and to replace the exhaust muffler when cracks are found.
Full official abstract
Airworthiness Directives; Liberty Aerospace Incorporated Model XL-2 Airplanes
We are adopting a new airworthiness directive (AD) for certain Liberty Aerospace Incorporated Model XL-2 airplanes. This AD requires you to repetitively inspect the exhaust muffler for cracks and to replace the exhaust muffler when cracks are found. This AD is the result of reports that cracks have been found in the exhaust muffler during maintenance and service inspections. We are issuing this AD to detect and correct cracks in the exhaust muffler, which could result in carbon monoxide entering the cabin through the heating system. Carbon monoxide entering into the airplane cabin could lead to incapacitation of the pilot.
