Availability and Summary of 

Documents for Incorporation by 

Reference 

This document proposes to amend 

FAA Order 7400.11E, Airspace 

Designations and Reporting Points, 

dated July 21, 2020, and effective 

September 15, 2020. FAA Order 

7400.11E is publicly available as listed 

in the ADDRESSES section of this 

document. FAA Order 7400.11E lists 

Class A, B, C, D, and E airspace areas, 

air traffic service routes, and reporting 

points. 

The Proposal 

The FAA is proposing an amendment 

to 14 CFR part 71 by: 

Amending the Class D airspace to 

within a 4.3-mile (increased from a 4.2- 

mile) radius of Ardmore Municipal 

Airport, Ardmore, OK; updating the 

geographic coordinates of the airport to 

coincide with the FAA’s aeronautical 

database; and replacing the outdated 

term ‘‘Airport/Facility Directory’’ with 

‘‘Chart Supplement’’; 

Amending the Class E airspace area 

designated as an extension to Class D 

airspace at Ardmore Municipal Airport 

within 1.4 (increased from 1.3) miles 

each side of the Ardmore VORTAC 050° 

(previously 056°) radial extending from 

the 4.3-mile (increased from 4.2-mile) 

radius of airport to 7.4 (decreased from 

8.4) miles southwest of airport; updating 

the geographic coordinates of the airport 

to coincide with the FAA’s aeronautical 

database; and replacing the outdated 

term ‘‘Airport/Facility Directory’’ with 

‘‘Chart Supplement’’; 

And amending the Class E airspace 

extending upward from 700 feet above 

the surface at Ardmore Municipal 

Airport by adding an extension within 

1.5 miles each side of the Ardmore 

VORTAC 050° radial extending from the 

6.8-mile radius of the airport to 8.4 

miles southwest of the airport; within 

1.1 miles each side of the 315° bearing 

from the airport extending from the 6.8- 

mile radius of the airport to 7 (increased 

from 6.9) miles northwest of the airport; 

updating the geographic coordinates of 

the airport to coincide with the FAA’s 

aeronautical database; and removing the 

extension northwest of the Ardmore 

VORTAC as it is no longer required. 

These actions are the result of 

airspace reviews caused by the 

decommissioning of the Arbuckle NDB 

which provided guidance to instrument 

procedures at these airports. 

Class D and Class E airspace 

designations are published in paragraph 

5000, 6004, and 6005, respectively, of 

FAA Order 7400.11E, dated July 21, 

2020, and effective September 15, 2020, 

which is incorporated by reference in 14 

CFR 71.1. The Class D and E airspace 

designations listed in this document 

will be published subsequently in the 

Order. 

FAA Order 7400.11, Airspace 

Designations and Reporting Points, is 

published yearly and effective on 

September 15. 

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, is non-controversial and 

unlikely to result in adverse or negative 

comments. 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 will only affect air 

traffic procedures and air navigation, it 

is certified that this rule, when 

promulgated, would 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

Pilots’ Medical Certificate Validity 

Period 

AGENCY: Coast Guard, DHS. 

ACTION: Notice of proposed rulemaking. 

SUMMARY: The Coast Guard proposes to 

extend the maximum period of validity 

of merchant mariner medical certificates 

issued to first-class pilots and masters or 

mates serving as pilot from 2 years to 5 

years. This proposed rule would reduce 

the frequency of medical certification 

application submissions to the Coast 

Guard. First-class pilots and masters 

and mates who serve as pilot on vessels 

of 1,600 gross registered tons or more 

would be required to submit the results 

of their annual physical examinations to 

the Coast Guard between medical 

certificate applications if: The mariner 

does not meet the physical ability 

requirements; the mariner has a 

condition that does not meet the 

medical, vision, or hearing 

requirements; the mariner is deemed 

‘‘not recommended’’ by a medical 

practitioner for a medical certificate; or 

upon request by the Coast Guard. The 

proposed rule will not compromise 

safety because it maintains the 

requirement for pilots to obtain annual 

physicals and because it provides the 

Coast Guard opportunity to review the 

medical examination of pilots who may 

become medically unqualified between 

medical certificate applications. 

DATES: Comments and related material 

must be received by the Coast Guard on 

or before October 26, 2021. 

ADDRESSES: You may submit comments
