**AGENCY:**
Federal Aviation Administration (FAA), DOT.
**ACTION:**
Final rule.
**SUMMARY:**
This action modifies the Class E airspace extending upward from 700 feet above the surface at Driggs/Reed Memorial Airport, Driggs, ID. Additionally, this action updates the administrative portion of the airport's Class E airspace legal description. These actions support the safety and management of instrument flight rules (IFR) operations at the airport.
**DATES:**
Effective date 0901 UTC, May 14, 2026. The Director of the *Federal Register* approves this incorporation by reference action under 1 CFR part 51, subject to the annual revision of FAA Order JO 7400.11 and publication of conforming amendments.

**SUPPLEMENTARY INFORMATION:**
**Authority for This Rulemaking**
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 Class E airspace to support IFR operations at Driggs/Reed Memorial Airport, Driggs, ID.
**History**
The FAA published an NPRM for Docket No. FAA-2025-4543 in the *Federal Register* (90 FR 53248; November 25, 2025), proposing to modify the Class E airspace at Driggs/Reed Memorial Airport, Driggs, ID. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received.
**Differences From the NPRM**
The FAA identified a typographical error within the NPRM after publication. A portion of the Class E airspace legal description proposed for Driggs/Reed Memorial Airport, Driggs, ID, was described as being “within an area 1.2 miles northwest and 3.4 miles southeast of the airport's 028° bearing extending to its 5.8-mile radius.” The phrase is corrected to read “5.7-mile radius” within the Final Rule.
**Incorporation by Reference**
Class E5 airspace designations are published in paragraph 6005 of FAA Order JO 7400.11, which is incorporated by reference in 14 CFR 71.1 on an annual basis. This document amends the current version of that order, FAA Order JO 7400.11K, dated August 4, 2025, and effective September 15, 2025. These amendments will be published in the next update to FAA Order JO 7400.11. FAA Order JO 7400.11K, which lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points, is publicly available as listed in the *ADDRESSES* section of this document.
**The Rule**
The FAA amends 14 CFR part 71 by modifying the Class E airspace extending upward from 700 feet above the surface at Driggs/Reed Memorial Airport, ID. The Class E airspace surrounding the airport is reduced due to modifications made to the airport's instrument flight procedures (IFP) that allow for more condensed containment within controlled airspace.
The northern extension is narrowed by 4.3 miles and shortened by 5.5 miles to more appropriately contain the Area Navigation (RNAV) (Global Positioning System [GPS])-A approach procedure. The southwest extension is narrowed by 1.3 miles, shortened by 1.3 miles, and shifted a half mile west to more appropriately contain the RNAV (GPS) Runway 4 approach procedure. The southeastern third of the existing airspace is removed, as it is no longer needed for the containment of IFPs. The western portion of the airspace is removed beyond the airport's 4.8-mile radius, approximately between the airport's 220° and 315° radials, as it is no longer needed for IFP containment.
Finally, the airport's geographic location within its Class E airspace legal description is updated to match the FAA's database.
**Regulatory Notices and Analyses**
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. It, therefore: (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 only affects air traffic procedures and air navigation, it is certified that this rule, when promulgated, does not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
**Environmental Review**
The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with FAA Order 1050.1G, “FAA National Environmental Policy Act Implementing Procedures,” paragraph B-2.5. This airspace action is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exist that warrant preparation of an environmental assessment.
