# [Amended]
**AGENCY:**
Federal Aviation Administration (FAA), DOT.
**ACTION:**
Notice of proposed rulemaking (NPRM).
**SUMMARY:**
This action proposes to amend Class D, Class E2, Class E4, and Class E5 airspace at Patuxent River Naval Air Station (NAS) (Trapnell Field), Patuxent River, MD. The currently designated Class D, Class E2, and Class E4 airspace do not properly contain instrument flight rule (IFR) operations, which require controlled airspace. The geographic coordinates for Patuxent River NAS (Trapnell Field) would be updated in the airspace legal descriptions. The reference to the decommissioned Patuxent VORTAC would also be updated in the Class E2, Class E4, and Class E5 airspace legal descriptions. Last, the geographic coordinates for the Patuxent River NDB would also be updated in the Class E2 and Class E4 airspace legal descriptions.
**DATES:**
Comments must be received on or before February 2, 2026.

**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 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 would amend Class D, Class E2, Class E4, and Class E5 airspace in Patuxent River, MD.
**Comments Invited**
The FAA invites interested persons to participate in this rulemaking by submitting written comments, data, or views. Comments are specifically invited on the overall regulatory, aeronautical, economic, environmental, and energy-related aspects of the proposal. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should submit only one time if comments are filed electronically, or commenters should send only one copy of written comments if comments are filed in writing.
The FAA will file in the docket all comments it receives, as well as a report summarizing each substantive public contact with FAA personnel concerning this proposed rulemaking. Before acting on this proposal, the FAA will consider all comments it receives on or before the closing date for comments. The FAA will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. The FAA may change this proposal in light of the comments it receives.
*Privacy:* In accordance with 5 U.S.C. 553(c), DOT solicits comments from the public to better inform its rulemaking process. DOT posts these comments, without edits, including any personal information the commenter provides, to *www.regulations.gov,* as described in the system of records notice (DOT/ALL-14 FDMS), which can be reviewed at *www.dot.gov/privacy.*

**Incorporation by Reference**
Class D, Class E2, Class E4, and Class E5 airspace designations are published in paragraphs 5000, 6002, 6004, and 6005 of FAA Order JO 7400.11, Airspace Designations and Reporting Points, which is incorporated by reference in 14 CFR 71.1 on an annual basis. This document proposes to amend the current version of that order, FAA Order JO 7400.11K, dated August 4, 2025, and effective September 15, 2025. These updates would 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 Proposal**
This action proposes to amend 14 CFR part 71 by modifying the Class D, Class E2, Class E4, and Class E5 airspace for Patuxent River NAS (Trapnell Field), Patuxent River, MD. Controlled airspace is necessary for the safety and management of IFR operations in the area for existing instrument approach procedures.
This action proposes to amend the Class D airspace over Patuxent River, MD, by updating the Patuxent River NAS (Trapnell Field) geographic coordinates and increasing the lateral boundary of the Class D airspace to within a 4.7-mile radius of Patuxent River NAS (Trapnell Field) and within a .5-mile radius of Chesapeake Ranch Airpark excluding that airspace within Restricted Areas R-4005 and R-4007 when active. The superseded reference to the “Airport Facility Directory” would also be replaced with “Chart Supplement” in the airspace legal description.
This action also proposes to amend the Class E2 airspace over Patuxent River, MD, by updating the geographic coordinates of Patuxent River NAS (Trapnell Field) and modifying the dimensions from the current configuration to that airspace extending upward from the surface within a 4.7-mile radius of Patuxent River NAS (Trapnell Field) and within 1.8 miles each side of the 047° bearing from Patuxent River NAS extending from the 4.7-mile radius of Patuxent River NAS to 6.5 miles northeast of the airport; and within 1.9 miles each side of the 233° bearing from Patuxent River NAS extending from the 4.7-mile radius to 6.2 miles southwest of the airport; and within 1.8 miles each side of the 137° bearing from Patuxent River NAS extending from the 4.7-mile radius to 10.8 miles southeast of the airport; and within a .5-mile radius of Chesapeake Ranch Airpark, excluding that airspace within Restricted Areas R-4005 and R-4007 when active. This reconfiguration would properly contain the currently published standard instrument approach procedures. The reference to the decommissioned Patuxent VORTAC in the Class E2 legal description would also be removed, and the geographic coordinates of the Patuxent River NDB would be updated.
This action also proposes to amend the Class E4 airspace over Patuxent River, MD, by updating the geographic coordinates of Patuxent River NAS (Trapnell Field) and modifying the dimensions from the current configuration to that airspace extending upward from the surface within 1.8 miles each side of the 047° bearing from Patuxent River NAS extending from the 4.7-mile radius of Patuxent River NAS to 6.5 miles northeast of the airport; and within 1.9 miles each side of the 233° bearing from Patuxent River NAS extending from the 4.7-mile radius to 6.2 miles southwest of the airport; and within 1.8 miles each side of the 137° bearing from Patuxent River NAS extending from the 4.7-mile radius to 10.8 miles southeast of the airport, excluding that airspace within Restricted Areas R-4005 and R-4007 when active. This reconfiguration will properly contain the currently published standard instrument approach procedures. Additionally, the reference to the decommissioned Patuxent VORTAC in the Class E4 legal description would be removed; the superseded reference to the “Airport Facility Directory” would be replaced with “Chart Supplement”; and the geographic coordinates of the Patuxent River NDB would be updated.
Lastly, this action proposes to amend the Class E5 airspace over Patuxent River, MD, by replacing the reference to the decommissioned Patuxent VORTAC with point in space coordinates using the same geographic coordinates.
**Regulatory Notices and Analyses**
The FAA has determined that this proposed 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 Department of Transportation (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 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.
**Environmental Review**
This proposal will be subject to an environmental analysis in accordance with FAA Order 1050.1G, “FAA National Environmental Policy Act Implementing Procedures” prior to any FAA final regulatory action.
