          - [Docket No. FAA-2007-28529; Airspace Docket No. 07-ANM-12]

# AGENCY:

Federal Aviation Administration (FAA), DOT.

# ACTION:

 Final rule.

# SUMMARY:

This action will modify Class E airspace at Tucson, AZ. Additional controlled airspace is necessary to encompass holding patterns and intermediate segments at Tucson International Airport. The FAA is proposing this action to enhance the safety and management of Instrument Flight Rules (IFR) operations at Tucson International Airport, Tucson, AZ.

# DATES:

*Effective Date:*                         0901 UTC, June 5, 2008. The Director of the Federal Register approves this incorporation by reference action under 1 CFR part 51, subject to the annual revision of FAA                               ( print page 13123)                            Order 7400.9 and publication of conforming amendments.

# SUPPLEMENTARY INFORMATION:

## History

                    On August 29, 2007 the FAA published in the                     **Federal Register**                     a notice of proposed rulemaking to modify Class E airspace at Tucson, AZ (72 FR 49677). This action would enhance the safety and management of Instrument Flight Rules (IFR) operations at Tucson International Airport, Tucson, AZ.                

Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received.

Class E airspace designations are published in paragraph 6005 of FAA Order 7400.9R signed August 15, 2007, and effective September 15, 2007, which is incorporated by reference in 14 CFR part 71.1. The Class E airspace designations listed in this document will be published subsequently in that Order.

## The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 by modifying Class E airspace at Tucson International Airport, Tucson, AZ. Additional controlled airspace is necessary to encompass hold-in-lieu patterns at the LIPTE Initial Fix/Instrument Approach Fix (IF/IAF) at Tucson International Airport, Tucson, AZ and encompass intermediate segments from the ILEEN Distance Measuring Equipment (DME) fix to COPEY DME fix. The FAA is proposing this action to enhance the safety and management of IFR operations at Tucson International Airport, Tucson, AZ.

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 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 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. 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 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 controlled airspace at Tucson International Airport, Tucson, AZ.
