In October 2005, it was determined that continued operation of the Bishop, AK, NDB was in jeopardy at its current location because of riverbank erosion along the Yukon River to within 150 feet of the NDB site. This action is needed to reconfigure the airways to exclude the Bishop, AK, NDB. On December 8, 2005, the FAA published in the Federal Register a notice of proposed rulemaking to amend several Colored Federal Airways in Alaska (70 FR 72949). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal. One comment was received. The commenter suggested that the Bishop NDB should not be decommissioned until Global Positioning System (GPS) becomes a viable Instrument Flight Rules (IFR) navigation system. He pointed out that on some airway segments, made up from the Bishop NDB, Minimum Enroute Altitude (MEA) are lower than those on the associated Very High Frequency Omnidirectional Range airways. He also pointed out that he believes that the NDB will not be affected by Yukon River erosion for several years. The FAA has authorized IFR GPS navigation in Alaska at or above Minimum Instrument Altitudes (MIA) between published waypoints. MIA altitudes are available that are as low as NDB MEAs. Pilots may request GPS routings in the area affected by the loss of the Bishop NDB. The erosion of the Yukon River bank is impossible to accurately predict. For safety purposes, the Bishop NDB has been out of service for several months already. With the exception of editorial changes, this amendment is the same as that proposed in the notice.

Colored Federal Airways are published in paragraph 6009 of FAA Order 7400.9N dated September 1, 2005 and effective September 15, 2005, which is incorporated by reference in 14 CFR 71.1. The Colored Federal Airways listed in this document will be published substantial in the order.

The Rule

The FAA is amending to Title 14 Code of Federal Regulations (14 CFR) part 71 by revoking Colored Federal Airway B-12, modifying three Colored Federal Airways B-4, R-50 and G-7, and establishing Colored Federal Airway R-4 in Alaska. The FAA is taking this action to remove all airways and routes off the Bishop NDB, AK, in preparation for the NDB's eventual decommissioning from the NAS.

The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this regulation: (1) Is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under Department of Transportation 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.
