14 CFR Part 71

[Docket No. FAA-2008-0038; Airspace Docket No. 07-ANM-16]

 
Proposed Establishment of Low Altitude Area Navigation Routes (T-
Routes); Southwest Oregon

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: This action proposes to establish a low altitude Area 
Navigation (RNAV) route, designated T-274 in the State of Oregon. T-
routes are low altitude Air Traffic Service (ATS) routes, based on 
RNAV, for use by aircraft having instrument flight rules (IFR)-approved 
Global Positioning System (GPS)/Global Navigation Satellite System 
(GNSS) equipment. The FAA is proposing this action to enhance safety 
and improve the efficient use of the navigable airspace in the State of 
Oregon.

DATES: Comments must be received on or before March 31, 2008.

ADDRESSES: Send comments on this proposal to the Docket Management 
Facility, U.S. Department of Transportation, Docket Operations, M-30, 
1200 New Jersey Avenue, SE., West Building Ground Floor, Room W12-140, 
Washington, DC 20590-0001; telephone: (202) 366-9826. You must identify 
FAA Docket No. FAA-2008-0038 and Airspace Docket No. 07-ANM-16 at the 
beginning of your comments. You may also submit comments through the 
Internet at http://www.regulations.gov.

The postcard will be date/time stamped and returned to the commenter.
    All communications received on or before the specified closing date 
for comments will be considered before taking action on the proposed 
rule. The proposal contained in this action may be changed in light of 
comments received. All comments submitted will be available for 
examination in the public docket both before and after the closing date 
for comments. A report summarizing each substantive public contact with 
FAA personnel concerned with this rulemaking will be filed in the 
docket.

    Persons interested in being placed on a mailing list for future 
NPRM's should contact the FAA's Office of Rulemaking, (202) 267-9677, 
for a copy of Advisory Circular No. 11-2A, Notice of Proposed 
Rulemaking Distribution System, which describes the application 
procedure.

Low Altitude RNAV Route Identification and Charting

    Low altitude RNAV routes are identified by the letter ``T'' prefix 
followed by a three digit number. The ``T'' prefix is one of several 
International Civil Aviation Organization designators used to identify 
domestic RNAV routes. The FAA has been allocated the letter ``T'' 
prefix and the number block 200 to 500 for use in naming these routes. 
The FAA uses the ``T'' prefix for RNAV routes in the low altitude en 
route structure of the National Airspace System.
    T-routes are depicted in blue on the appropriate IFR en route low 
altitude chart(s).
    Each route depiction includes a GNSS minimum en route altitude to 
ensure obstacle clearance and communications reception.

The Proposal

    The FAA is proposing an amendment to Title 14 Code of Federal 
Regulations (14 CFR) part 71 to establish a low altitude RNAV route in 
Southwest Oregon. The route would be designated T-274, and would be 
depicted on the appropriate IFR En Route Low Altitude charts. T-routes 
are low altitude RNAV ATS routes, similar to Very High Frequency Omni 
directional Range Federal airways, but based on GNSS navigation. RNAV-
equipped aircraft capable of filing flight plan equipment suffix ``G'' 
may file for these routes.
    The T-route described in this notice is being proposed to enhance 
safety, and to facilitate the more flexible and efficient use of the 
navigable airspace for en route IFR operations transitioning through 
mountainous terrain of Southwest Oregon.

[[Page 8629]]

    Low altitude RNAV routes are published in paragraph 6011 of FAA 
Order 7400.9R signed August 15, 2007 and effective September 15, 2007, 
which is incorporated by reference in 14 CFR 71.1. The low altitude 
RNAV routes listed in this document would be published subsequently in 
the Order.
    The FAA has determined that this proposed regulation only involves 
an established body of technical regulations for which frequent and 
routine amendments are necessary to keep them operationally current. 
Therefore, this proposed regulation: (1) Is not a ``significant 
regulatory action'' under Executive Order 12866; (2) is not a 
``significant rule'' under Department of Transportation (DOT) 
Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); 
and (3) does not warrant preparation of a regulatory evaluation as the 
anticipated impact is so minimal. Since this is a routine matter that 
will only affect air traffic procedures and air navigation, it is 
certified that this proposed rule, when promulgated, will not have a 
significant economic impact on a substantial number of small entities 
under the criteria of the Regulatory Flexibility Act.
    The FAA's authority to issue rules regarding aviation safety is 
found in Title 49 of the United States Code. Subtitle I, Section 106 
describes the authority of the FAA Administrator. Subtitle VII, 
Aviation Programs, describes in more detail the scope of the agency's 
authority.
    This rulemaking is promulgated under the authority described in 
Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the 
FAA is charged with prescribing regulations to assign the use of the 
airspace necessary to ensure the safety of aircraft and the efficient 
use of airspace. This regulation is within the scope of that authority 
as it establishes RNAV T-Routes in Southwest Oregon.

Environmental Review

    The FAA has determined that this action qualifies for categorical 
exclusion under the National Environmental Policy Act in accordance 
with FAA Order 1050.1E, ``Environmental Impacts: Policies and 
Procedures,'' paragraph 311a, 311b, and 311k. This airspace action is 
not expected to cause any potentially significant environmental 
impacts, and no extraordinary circumstances exist that warrant 
preparation of an environmental assessment.
