This notice requests comments on proposed airworthiness standards for acceptance of the BA609 Tiltrotor under 14 CFR 21.17(b), designation of applicable regulations for special classes of aircraft for which airworthiness standards have not been issued.

Pursuant to Section 176 (c) of the Clean Air Act Amendments of 1990, the FAA announces the availability of the Final General Conformity Determination for Proposed Operations of Lynx Aviation, Inc. (Lynx), at Denver International Airport (DEN). FAA has determined that emissions from Lynx's operations at DEN conform to the applicable Colorado State Implementation Plans (SIPs). In accordance with the requirements of 40 CFR Sec. 93.156(b), FAA made the Draft Air Quality General Conformity Determination (Draft GCD) for Proposed Operations of Lynx Aviation, Inc., at Denver International Airport, Denver, CO available for public review beginning on July 20, 2007. FAA published notice of the draft determination in the ``Rocky Mountain News,'' Denver, Colorado on July 20 and 21, 2007 and DEN made copies of the draft determination available at the airport. FAA published the Notice of Availability and Public Comment Period for the Draft General Conformity Determination in the Federal Register on July 20, 2007 (72 FR 39877). FAA received one comment during the public comment period, which ended on August 20, 2007. The commenter stated that jet aviation activity results in excessive pollution and that there should be less aviation activity in general in the United States. The commenter did not provide comments specific to the Draft General Conformity Determination; therefore, a response to the comment is not necessary. Consequently, the Final General Conformity Determination consists of the Draft General Conformity Determination, with two typographical corrections. 1. Page 1, first sentence in the first paragraph under Introduction was revised to read: ``Lynx Aviation, Inc. (Lynx Aviation) has announced its interest in initiating scheduled service at Denver International Airport (DEN), now commencing in October 2007.'' 2. Page 3, first sentence in the second paragraph under Aircraft and Supportng Equipment Emissions was revised to read: ``Under the Proposed Action alternative, Lynx Aviation intends to introduce service at DEN on October 1, 2007.''
