Federal Aviation Administration (FAA), DOT.
Notice of proposed rulemaking.
This action proposes to revise Class E airspace at Mountain Home, ID, beginning at 1,200 feet above ground level (AGL), replacing the existing Class G uncontrolled airspace. This airspace action will accommodate the terminal environment transition between Salt Lake Air Route Traffic Control Center (ARTCC) and Mountain Home AFB Radar Approach Control (RAPCON) by placing aircraft in controlled airspace during the transfer of aircraft radar identification between the facilities. In addition, a review of the legal description revealed that it does not reflect the correct airport reference point (ARP) of Mountain Home Municipal Airport and geographic position of the Sturgeon Non-Directional Beacon (NDB). This action will correct those minor discrepancies.
Comments must be received on or before October 5, 2006.

Mountain Home AFB RAPCON works daily with Salt Lake ARTCC, transferring traffic between the facilities' airspace areas. The RAPCON's airspace has been charted into the ARTCC mapping file structure and extended to join with the Owyhee MOA boundary to the southwest of Mountain Home AFB. This wedge of airspace is outside the current 40 DME arc from the Mountain Home TACAN which accommodated the former approach control boundary to the southwest. The 46 DME arc brings that wedge into Class E airspace and is a fluid transition from adjoining Class E airspace along V113 to the southwest and around to V253 to the southeast, incorporating the northern portion of the Jarbridge MOA, accommodating the terminal environment transition and making control procedures more operationally efficient.
The FAA is proposing an amendment to Title 14 Code of Federal Regulations (14 CFR) part 71 to revise the Class E airspace area with a base altitude of 1,200 feet AGL in the vicinity of Mountain Home AFB, ID. Class E airspace is used to transition to and from the terminal or enroute environment, allowing a buffer for arriving and departing IFR aircraft from uncontrolled to controlled airspace. A review of the airspace in southern Idaho revealed a large area of uncontrolled (Glass G) airspace immediately adjacent to the (controlled) Class E airspace currently utilized by Mountain Home AFB RAPCON. Because this airspace is Class G below 14,500 feet mean sea level (MSL), Mountain Home AFB RAPCON does not have the authority to initiate IFR (Instrument Flight Rules) control instructions and vector aircraft transferred to them from Salt Lake ARTCC. IFR operations can take place in Class G, but the ability of the approach control to provide vectors, as an example, should not happen until within the confines of the approach control delegated airspace. The 46 DME arc provides for this buffer where transition from Class G to E can take place (arrival or departure), and allows the approach control in question to provide that vector within Class E. The Mountain Home AFB RAPCON airspace extends only to the 40 DME arc, and therefore, has no safe buffer currently established.
The proposed airspace revision incorporates into Class E airspace that portion of Mountain Home AFB RAPCON delegated airspace that was extended to join with the Owyhee MOA boundary to the Southwest of Mountain Home AFB. This wedge of airspace is outside the current 40 DME arc from the Mountain Home TACAN, which accommodated the former approach control boundary to the southwest.
In addition, the 6500 feet MSL Class E airspace to the southeast within the Jarbridge Military Operations Area (MOA) will be incorporated into this 1200 foot AGL Class E airspace. Neither Mountain Home AFB RAPCON nor Salt Lake ARTCC utilize this airspace at 6500 feet MSL, and containing it at 1200 feet AGL will allow Mountain Home AFB RAPCON to vector aircraft to Jarbridge MOA at lower altitudes.
Class E enroute domestic airspace areas are published in Paragraph 6005 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 Class E airspace designation listed in this document would be published subsequently in this Order.Start List of Subjects
