SUMMARY ORDER

UPON DUE CONSIDERATION, IT IS HEREBY ORDERED, ADJUDGED, AND DECREED that the petition for review is DENIED.

Petitioners Kenneth D. Paskar and Friends of LaGuardia Airport, Inc. seek review of an order of the FAA dismissing the City of New York (the “City”) from an action brought on a “Complaint and Request for Investigation” under Part 16 of the FAA regulations. 14 C.F.R. Part 16. Petitioners allege that the FAA and the City have violated grant assurances in agreements between the FAA and the Port Authority of New York and New Jersey (the “Port Authority”) for funding for LaGuardia Airport (“LaGuardia”).

Under § 46110(c) of the Federal Aviation Act, 49 U.S.C. § 46110(c), the FAA’s[*708] factual findings are conclusive if they are supported by “substantial evidence.” 49 U.S.C. § 46110(c). Under the Administrative Procedure Act, 5 U.S.C. § 706(2)(A), an agency’s application of law to fact is upheld unless it is “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law.” Natural Res. Def. Council, Inc. v. FAA, 564 F.3d 549, 555 (2d Cir.2009) (internal quotations omitted). This Court defers to the FAA’s interpretation of a statute if the interpretation is reasonable. Chevron U.S.A., Inc. v. Natural Res. Def. Council, Inc., 467 U.S. 837, 842-44, 104 S.Ct. 2778, 81 L.Ed.2d 694 (1984). We defer to the FAA’s interpretation of its own regulations unless the interpretation is “plainly erroneous or inconsistent with the regulation.” Auer v. Robbins, 519 U.S. 452, 461, 117 S.Ct. 905, 137 L.Ed.2d 79 (1997) (internal quotations omitted).

Upon review of the administrative record and consideration of the parties’ arguments, we hold that the FAA’s factual findings were supported by substantial evidence, and its application of the law to the facts is not arbitrary or capricious, or an abuse of discretion, or otherwise not in accordance with law. The City is not a signatory or party to the grant agreements, nor is it a proper Part 16 “respondent” as defined in 14 C.F.R. § 16.3, as the City is not a “sponsor, proprietor, or operator” of the airport. 14 C.F.R. § 13.3(d).

Although the City owns the land upon which LaGuardia sits, the Port Authority is the operator of LaGuardia and leases the land from the City. The City does not qualify as a “sponsor” under the terms of the grant agreement, statute, see 49 U.S.C. § 47102(26), or regulations, see 14 C.F.R. § 16.3, because it is not an agency that receives financial assistance from the FAA. The City is not a “proprietor” because ownership alone is not sufficient to warrant proprietor status, and the City does not “operate” the airport. See San Diego Unified Port Dist. v. Gianturco, 651 F.2d 1306, 1317 (9th Cir.1981) (holding that the owner, operator and promoter of an airport was the proprietor).

We have considered all of petitioners’ remaining arguments and conclude that they are without merit. Accordingly, the petition for review is DENIED.
