          - [Docket No. FAA-2023-1739]

# AGENCY:

Federal Aviation Administration (FAA), DOT.

# ACTION:

Proposed policy: request for comments; extension of comment period.

# SUMMARY:

                        On November 15, 2023, the Federal Aviation Administration (FAA) published a Request for comments seeking input on its proposed policy update of the FAA's Office of Airports policy regarding the definition of “aeronautical activity” to include unmanned aircraft systems (UAS), advanced air mobility (AAM), and commercial space launch or re-entry vehicle operations. Under Federal law, an airport operator that has accepted                               ( print page 85720)                            Federal grants or certain Federal land conveyances is obligated to maintain the airport for public aviation use. This proposed update will add UAS, AAM, and commercial space operations to the existing definition of aeronautical activity that is included in FAA Order 5190.6B, FAA Airport Compliance Manual, Appendix Z, and subsequent revisions. The comment period for the request for comments was scheduled to end on December 15, 2023. FAA received several requests to extend the comment period. The FAA is extending the comment period for the request for comments by 30 days.                    

# DATES:

The comment period to the request for comments published on November 15, 2023, 88 FR 78448, is extended from December 15, 2023, to January 15, 2024.

# SUPPLEMENTARY INFORMATION:

## I. Background

                    Under Federal law, Airport owners/operators (“sponsors”) that have accepted grants under the Airport Improvement Program (AIP) must comply with certain Federal policies included in each AIP grant agreement as sponsor assurances. In addition, sponsors who have acquired land from the Federal government using certain conveyance instruments must abide by similar obligations included in property deeds. The Airport and Airway Improvement Act of 1982 (AAIA) (Pub. L. 97-248), as amended and recodified at 49 U.S.C. 47107(a)(1), as implemented by Sponsor Assurance 22,                     *Economic Nondiscrimination,*                     requires that “the airport will be made available for public use on reasonable conditions and without unjust discrimination to all types, kinds and classes of aeronautical activities, including commercial aeronautical activities offering services to the public at the airport.” The FAA defines aeronautical activities as any activity that involves, makes possible, is required for the operation of an aircraft/vehicle, or that contributes to or is required for the safety of such operations (FAA Order 5190.6B,                     *Airport Compliance Manual,*                     Appendix Z, (2009)). The order lists examples of aeronautical activities.                

The FAA's definition has evolved over time, primarily in response to emerging technologies and increased interest in locating certain activities at public use airports not previously contemplated or subject to FAA oversight. This updated definition serves to accommodate commercial space transportation, UAS, and AAM activities, as well as supports Congressional interest in integrating new technology into the array of services and capabilities offered by federally funded airports. As a result, the FAA believes that commercial space activities, UAS, and AAM operations should be considered aeronautical activities for the purposes of access to a federally-obligated airport.

However, some types of commercial space, UAS, or AAM operations may affect the safety of existing airport facilities, airport operations, or the efficiency of the airspace. Consistent with and in support of the airport sponsor's obligation not to introduce or permit unsafe conditions at the airport, and to mitigate such conditions if they arise, the FAA uses its planning approval, safety review, and/or risk assessment processes to make a determination on (1) whether a particular activity can be safely accommodated at the airport and, if so, (2) the terms and conditions to mitigate risk to an acceptable level for that activity at the airport. In that regard, Congress has made the FAA the final arbiter regarding aviation safety (49 U.S.C. 40101 and 47101.)

## II. The Proposed Policy

                    The updated definition of aeronautical activity in FAA Order 5190.6B,                     *FAA Airport Compliance Manual,*                     Appendix Z will be the following:                

Any activity that involves, makes possible, or is required for the operation of an aircraft, launch or reentry vehicle, or that contributes to or is required for the safety of such operations. It includes but is not limited to: general and corporate aviation, air taxi and charter operations, scheduled and nonscheduled air carrier operations, pilot training, aircraft rental and sightseeing, aerial photography, aerial application of agricultural agents, aerial advertising and surveying, aircraft sales and services, aircraft storage, sale of aviation fuel products, repair and maintenance of aircraft, repair and maintenance of launch or reentry vehicles, construction of amateur-built/recreational aircraft, sale of aircraft, sale of launch or reentry vehicle parts, parachute or ultralight activities, certain unmanned aircraft systems (UAS), advanced air mobility (AAM) operations, commercial space vehicle operations, and any other activities that because of their direct relationship to the operation of aircraft, UAS, or commercial space launch and re-entry vehicles can appropriately be regarded as aeronautical activities.

                    Activities such as aircraft and parts manufacturing and storage, aerospace design, research and development, flight simulation/training/management facilities, and/or engine testing facilities that are not associated with the final assembly of an aircraft or commercial space vehicle are not considered aeronautical activities for the purposes of airport access. Model rocket, model aircraft, and recreational UAS                           ( print page 85721)                        operations are not aeronautical activities for the purposes of airport access.

Director, Office of Airport Compliance and Management Analysis.
