Notice of proposed rulemaking (NPRM).


This action proposes to establish two new low-altitude RNAV routes, designated T-306 and T-310, in southwestern United States. The new routes would expand the availability of RNAV within the National Airspace System (NAS) and provide substitute route segments for portions of VOR Federal airways V-16 and V-202.


Comments must be received on or before June 7, 2012.

Persons interested in being placed on a mailing list for future NPRMs 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.

The Proposal

The FAA is proposing an amendment to Title 14, Code of Federal Regulations (14 CFR) part 71 to establish two new low altitude RNAV routes in southwestern United States. Route T-306 would extend between Los Angeles, CA, and El Paso, TX; and route T-310 would extend between Tucson, AZ, and Truth or Consequences, NM. The routes would expand the availability of RNAV within the NAS and provide substitute route segments for portions of VOR Federal airways V-16 and V-202 that will be affected by the scheduled decommissioning of the Cochise, NM, VORTAC in the Fall of 2012.

This action would enhance en route navigation for users, increase the efficiency of the NAS and expand the use of RNAV within the NAS.

RNAV routes are published in paragraph 6011 of FAA Order 7400.9V dated August 9, 2011, and effective September 15, 2011, which is incorporated by reference in 14 CFR 71.1. The RNAV routes listed in this document would be subsequently published 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 modifies the route structure as required to preserve the safe and efficient flow of air traffic.

Environmental Review

This proposal will be subject to an environmental analysis in accordance with FAA Order 1050.1E, “Environmental Impacts: Policies and Procedures,” prior to any FAA final regulatory action.
