# AGENCY:

Federal Aviation Administration (FAA), DOT.

# ACTION:

Notice of Proposed Rulemaking.

# SUMMARY:

This action proposes to revise Class D airspace at Mesa, AZ, Falcon Field Airport. The airspace would be modified to accommodate general aviation pilots transitioning the Phoenix area as described in the forthcoming proposed Phoenix Class B airspace redesign. Revising the Falcon Field airspace will provide a wider corridor for general aviation pilots to transition north and south beneath the proposed Phoenix Class B airspace and remain west of the Falcon Field Airport Class D airspace.

# DATES:

Comments must be received on or before December 11, 2006.

## Background

Phoenix Class B airspace is in the process of being redesigned. Assuming establishment of the redesign, the eastern boundaries of Class B will change, resulting in an airspace area designated with a floor of 2,700 feet Mean Sea Level (MSL) between six nautical miles and approximately 9.19 nautical miles east of Phoenix VORTAC.

Currently, the Mesa Falcon Field Class D airspace is within a 4.3 nautical mile radius of the Mesa Falcon Field Airport ARP (Airport Reference Point) from the surface to less than 3,400 feet MSL. Class B airspace with a floor of 3,000 feet MSL is captured between the visual reference points of Dobson Road and Gilbert Road, excluding the Mesa Falcon Field Class D airspace. Beneath this airspace area is a suggested VFR flyway utilized by general aviation pilots to traverse the Phoenix area at 2,500 feet MSL.

In the proposed Class B airspace redesign, much of the 3,000 feet MSL airspace floor with change to 2,700 feet MSL. In order to provide the widest possible corridor of airspace of general aviation use under 2,700 feet MSL, it is proposed that a western boundary of Mesa Falcon Field Class D airspace be designated at Gilbert Road.

                    In addition to this available airspace below 2,700 feet MSL, the proposed suggested VFR flyway utilized by general aviation will be moved east of Gilbert Road over Mesa Falcon Field Class D airspace at 3,500 feet MSL, which will be below the Class B floor of 4,000 feet MSL, thus providing a designated suggested VFR flyway as well as more transition area for general aviation below the 2,700 feet MSL Class B airspace.                          ( print page 62398)    

## The Proposal

The FAA is proposing an amendment to Title 14 Code of Federal Regulations (14 CFR) part 71 to revise the Class D airspace area. Utilizing a 6-nautical-mile Distance Measuring Equipment (DME) arc from the Phoenix VORTAC eastward to Gilbert Road, the proposed Class B airspace, in association with this proposed Class D airspace area revision, would provide a similar general aviation airspace transition area between approximately 3.17 and 5 nautical miles wide beneath its floor of 2,700 feet MSL. This area encompasses a small portion of the Mesa Falcon Field Airport Class D airspace area.

In order to accommodate general aviation transitioning north and south below the proposed Class B airspace, and provide an eastern visual boundary and the widest possible corridor of VFR airspace under 2,700 feet MSL between the 6-nautical-mile DME arc and Gilbert Road, it is proposed to revise the Class D airspace to extend only as far west as Gilbert Road; thus allowing aircraft to remain below Class B airspace and outside and to the west of Class D airspace during its hours of operation.

Class D airspace areas are published in Paragraph 5000 of FAA Order 7400.9P dated September 1, 2006, and effective September 15, 2006, which is incorporated by reference in 14 CFR 71.1. The Class D airspace designation listed in this document would be published subsequently in this Order.
