Plaintiff-Appellant US Airways, Inc. (“US Airways”) filed this action in the United States District Court for the District of New Mexico seeking to enjoin Defendants-Appellees New Mexico state officials (“New Mexico”) from regulating, pursuant to the New Mexico Liquor Control Act (“NMLCA”), N.M. Stat. § 60-3A-1 et seq., the alcoholic beverage service that airlines provide to passengers on flights. The district court concluded that federal law does not preempt the NMLCA and granted summary judgment for New Mexico. US Airways appeals that decision.
On appeal, U.S. Airways argues that the Airline Deregulation Act of 1978 (“ADA”) expressly preempts state regulation of airlines’ alcoholic beverage services provided to passengers. In addition to express preemption, U.S. Airways argues that federal law impliedly preempts the application of the NMLCA to U.S. Airways. Specifically, U.S. Airways contends that the Federal Aviation Act of 1958 (“FAA”) and the federal regulations promulgated pursuant to the FAA occupy the field of aviation safety to the exclusion of state regulation and *1322 that NMLCA’s application to an airline implicates the field of aviation safety. Exercising jurisdiction under 28 U.S.C. § 1291, we conclude that New Mexico’s regulatory scheme is impliedly preempted as it falls within the field of aviation safety that Congress intended federal law to occupy exclusively, but that the Twenty-first Amendment of the United States Constitution requires a balancing of New Mexico’s core powers and the federal interests underlying the FAA. Accordingly, we reverse and remand for the district court to conduct a Twenty-first Amendment balancing.

A.
NMLCA regulates the sale, service and public consumption of alcoholic beverages in the State of New Mexico. See N.M. Stat. § 60-3A-1 et seq. NMLCA states, in relevant part, that “[ejvery person selling alcoholic beverages to travelers on ... airplanes within the state shall secure a public service license.” N.M. Stat. § 60-6A-9. Further, NMLCA prohibits any person from being “employed as a server on a licensed premises unless that person obtains within thirty days of employment alcohol server training pursuant to the provisions of [N.M. Stat. § 60-6E-1 et seq.].” N.M. Stat. § 60-6E-4.

US Airways, an interstate airline carrier regulated by the Federal Aviation Administration of the United States Department of Transportation, operates flights that travel to and from the State of New Mexico at the Albuquerque International Sun-port Airport. See Aplt.App. at A325, A1015. These flights generally originate from or arrive at locations outside New Mexico. See id. at A329, A1015.
US Airways serves alcoholic beverages during its flights, including those that arrive in and depart from New Mexico. Id. at A1015. However, passengers are not permitted to remove from the aircraft the alcoholic beverages served during flight. Id. at A1231. Further, the U.S. Airways beverage carts containing the alcoholic beverages are not removed from the aircraft in New Mexico. Id. at A330-31, A1231-32. US Airways does not stock its aircraft with alcoholic beverages and does not purchase or store such beverages in New Mexico. Id. at A330. Prior to 2007, U.S. Airways provided alcoholic beverage service to passengers on flights departing from and arriving in New Mexico without possessing a public service license as required by NMLCA. See id. at A1016, A1231.
C.
In November 2006, Dana Papst was a passenger on a U.S. Airways flight departing from Phoenix, Arizona and arriving in Albuquerque, New Mexico. Id. at A1016. He allegedly purchased and consumed alcoholic beverages during his U.S. Airways flight. See id. at A1017. During his drive home from the Albuquerque airport and approximately three hours after deplaning, he caused an automobile accident that resulted in his death and the death of five others. Id. at A589, A1232. An analysis of Papst’s blood drawn after the accident revealed that Papst’s blood alcohol content was approximately 0.329. See id. at A1232. After conducting an investigation of the incident, the Federal Aviation Administration declined to take any action against U.S. Airways or its employees. Id. at A32, A1233.
In January 2007, the Alcohol and Gaming Division (“AGD”) of the New Mexico Regulation and Licensing Department served U.S. Airways with a citation assert *1323 ing that U.S. Airways had served alcohol to an intoxicated person, namely Dana Papst. Id. at A33. The AGD also served U.S. Airways with a cease-and-desist order directing U.S. Airways to “refrain from selling, serving and otherwise dispensing, storing or possessing alcoholic beverages of any kind in the State of New Mexico” without properly complying with the requirements of NMLCA. Id. at A35-38.
In February 2007, while noting its belief that federal law preempted the application of NMLCA to an airline, U.S. Airways applied for a public service license to serve alcoholic beverages to passengers on aircraft in New Mexico. Id. at A43. In response to the application, AGD issued U.S. Airways a ninety-day temporary license. See id. at A51. However, in June 2007, AGD declined to extend U.S. Airways’ temporary license explaining that U.S. Airways’ alcohol server training did not comply with NMLCA’s requirements. Id. at A86-88. AGD ultimately rejected U.S. Airways’ application for a license in November 2007 citing as reasons for the denial the Dana Papst incident and another incident which involved a passenger who had been served alcoholic beverages on a U.S. Airways flight and was apprehended for driving while intoxicated approximately an hour after he had deplaned at Albuquerque. Id. atA404-05.
D.
US Airways filed this action seeking to “enjoin New Mexico state officials [in the AGD and the New Mexico Regulation and Licensing Department] from enforcing laws that purport to govern U.S. Airways’ alcoholic beverage service on flights departing from or arriving into New Mexico.” Id. at A6 (Compl. at 1). US Airways asserted both express and implied preemption in support of its request for injunction. Id. at A6-9 (Compl. at 1-4). Specifically, U.S. Airways argued that the enforcement of NMLCA against an airline violated the Supremacy Clause of the United States Constitution as the ADA expressly preempts state regulation of airline services, including the alcoholic beverage service provided to passengers on flights. Id. Alternatively, U.S. Airways contended that federal law impliedly preempts the application of NMLCA to airlines as the application of NMLCA to an airline implicates the field of aviation safety, which federal law regulates to the exclusion of state regulation. Id. Further, U.S. Airways asserted that New Mexico’s regulatory efforts could not be otherwise authorized pursuant to the Twenty-first Amendment to the United States Constitution. Id.
The parties filed cross-motions for summary judgment. See id. at A1265 (Op. at 1). The district court concluded that federal law neither expressly nor impliedly preempts New Mexico’s regulation of the alcoholic beverage service that airlines provide. Id. at A1287 (Op. at 23). Specifically, the district court narrowly construed the explicit preemption provision in the ADA, concluding that the provision’s reference to “service” did not include an airline’s alcoholic beverage service. See id. at A1283 (Op. at 19). The district court reasoned that the narrow interpretation necessarily avoided rendering the ADA preemption provision violative of § 2 of the Twenty-first Amendment. See id. at A1275 (Op. at 11). Further, the district court addressed field preemption and concluded that federal law did not preempt the field of alcohol service on airlines. Id. at A1287 (Op. at 23). In reaching this decision, the district court reasoned that, when enacting the FAA, “Congress was addressing the need for exclusive and complete rules for the physical and mechanical operation of aircraft.” Id. at A1285 (Op. at *1324 21). The district court then denied U.S. Airways’ motion for summary judgment and granted New Mexico’s motion. Id. at A1287 (Op. at 23).
II.
“We review the district court’s grant of summary judgment de novo, applying the same legal standard as the district court.”
Christian Heritage Acad. v. Okla. Secondary Sch. Activities Ass’n,
On appeal, U.S. Airways reasserts its contention that federal law both expressly and impliedly preempts NMLCA’s regulation of an airline’s alcoholic beverage service provided on aircraft. Aplt. Br. at 1. Further, U.S. Arways argues that New Mexico cannot avoid the preemption of NMLCA’s application to an airline’s alcoholic beverage service by applying the Twenty-first Amendment. Id.
A. Preemption
The Supremacy Clause provides that the laws of the United States “shall be the supreme Law of the Land; ... any Thing in the Constitution or Laws of any State to the Contrary notwithstanding.” U.S. Const, art. VI, cl. 2. Pursuant to this provision, Congress has the power to enact statutes that preempt state law.
Nw. Cent. Pipeline Corp. v. State Corp. Comm’n of Kan.,
There are three types of preemption: 1) “express preemption, which occurs when the language of the federal statute reveals an express congressional intent to preempt state law;” 2) “field preemption, which occurs when the federal scheme of regulation is so pervasive that Congress must have intended to leave no room for a State to supplement it;” and 3) “conflict preemption, which occurs either when compliance with both the federal and state laws is a physical impossibility, or when the state law stands as an obstacle to the accomplishment and execution of the full purposes and objectives of Congress.”
Mount Olivet Cemetery Ass’n v. Salt Lake City,
1.
Field preemption occurs when a “state law ... regulates conduct in a field that Congress intended the Federal Gov
*1325
ernment to occupy exclusively.”
English v. Gen. Elec. Co.,
When conducting a field preemption analysis, we must first identify the legislative field that the state law at issue implicates.
See Martin ex rel. Heckman v. Midwest Express Holdings, Inc.,
Additionally, NMLCA’s regulatory scheme extends beyond the field of airline alcoholic beverage services. Specifically, NMLCA prescribes training and certification requirements for flight attendants and other airline crew members serving alcoholic beverages on aircraft. See N.M. Stat. § 60-6E-4 (“No person shall be employed as a server on a licensed premises unless that person obtains within thirty days of employment alcohol server training pursuant to the provisions of [N.M. Stat. § 60-6E-1 et seq.].”); N.M. Stat. § 60-6E-5(B) (delineating the subjects that the training program for employees serving alcoholic beverages must cover). Thus, we conclude that New Mexico’s regulatory scheme as applied to an airline generally implicates the field of aviation safety.
2.
Having identified the legislative field at issue, we must next evaluate whether Congress intended to occupy the field to the exclusion of the states.
See Martin ex rel. Heckman,
*1326
While we have previously held that Congress did not indicate “ ‘a clear and manifest’ intent to occupy the field of airplane safety to the exclusion of state common law,”
Cleveland v. Piper Aircraft Corp.,
Further, we have recognized that our analysis in
Cleveland
has been called into question based on subsequent Supreme Court opinions.
See Choate v. Champion Home Builders Co.,
Based on the FAA’s purpose to centralize aviation safety regulation and the comprehensive regulatory scheme promulgated pursuant to the FAA, we conclude that federal regulation occupies the field of aviation safety to the exclusion of state regulations. The FAA was enacted to create a “uniform and exclusive system of federal regulation” in the field of air safety.
City of Burbank v. Lockheed Air Terminal Inc.,
The language of the FAA explicitly directs the Administrator of the Federal Aviation Administration to promulgate regulations for the “safe flight of civil aircraft in air commerce.” 49 U.S.C. § 44701(a). Beyond the types of regulations specifically enumerated, the FAA directs the Administrator to regulate any
*1327
“other practices, methods, and procedure the Administrator finds necessary for safety in air commerce and national security.”
Id.
The Federal Aviation Administration has exercised its authority pursuant to the FAA to promulgate regulations addressing “virtually all areas of air safety.”
Air Transp. Ass’n of Am., Inc. v. Cuomo,
Other circuits have similarly concluded that Congress intended federal law to occupy the entire field of aviation safety exclusively.
See Montalvo,
3.
Having addressed the field of aviation safety generally, we must consider whether the NMLCA implicates the field as occupied by federal law. Even if we narrowly define the field of aviation safety, we conclude that NMLCA’s regulation of an airline’s alcoholic beverage service directly implicates the field of aviation safety regulated by federal law. As noted, the Federal Aviation Administration has promulgated a federal regulation specifically addressing airlines’ alcoholic beverage services. See 14 C.F.R. § 121.575. 2 Notably, *1328 the Federal Aviation Administration promulgated this regulation to promote aviation safety. See Drinking and Serving of Alcoholic Beverages, 25 Fed.Reg. 168, 168-69 (Jan. 9, 1960) (“The Agency’s responsibility is only for the air safety considerations and not for the social or moral aspects” of alcohol consumption.). Specifically, the Federal Aviation Administration balanced the safety concerns inherent in regulating airline alcoholic beverage service against the imposition of additional responsibilities on flight crew members. See id. (explaining that airline flight crew members would not have the responsibility to “restrain physically a passenger who wished to consume drinks that were not served to him by the carrier”). Additionally, the Federal Aviation Administration considered whether the proposed provision adequately addressed safety concerns, noting that “flat prohibition [of alcohol on aircraft] has not proven successful” and “it might even work adversely, since passengers who wish to drink might ... do so to excess in advance of the flight, knowing that they could not obtain a drink aboard an aircraft.” Id. at 170. Thus, NMLCA implicates the field of aviation safety as occupied by federal law.
Further, New Mexico’s regulatory efforts extend beyond the alcoholic beverage service that airlines provide on flights. By requiring airlines to comply with NMLCA, New Mexico is seeking to impose additional training requirements on flight attendants and crew members serving alcoholic beverages on airplanes. See N.M. Stat. § 60-6E-4 (“No person shall be employed as a server on a licensed premises unless that person obtains within thirty days of employment alcohol server training pursuant to the provisions of [N.M. Stat. § 60-6E-1 et seq.].”); N.M. Stat. § 60-6E-5(B) (delineating the subjects that the training program for employees serving alcoholic beverages must cover). In fact, when New Mexico denied the renewal of U.S. Airways’ temporary public service license, New Mexico noted that U.S. Airways “ha[d] done little if anything to consider implementing applicable portions of [New Mexico’s] required alcohol server training.” Aplt.App. at A87. However, federal law extensively regulates flight attendant and crew member training programs and certification requirements due to the aviation safety considerations involved. See 49 U.S.C. § 44728(a)(1) (“No person may serve as a flight attendant aboard an aircraft of an air carrier unless that person holds a certificate of demonstrated proficiency from the Administrator of the Federal Aviation Administration....”); 14 C.F.R.. §§ 121.404 (requiring that flight attendants and aircraft dispatchers “complete! ] approved crew resource management ... or dispatcher resource management ... initial training”), 121.405 (explaining the approval process for training programs or revisions to existing training programs), 121.415 (delineating the training program requirements), 121.421 (describing the initial and transi *1329 tion ground training requirements for flight attendants), 121.427 (explaining the recurrent training requirements for crew members and dispatchers), 121.433 (describing the mandatory crew member training requirements). Thus, NMLCA’s regulatory scheme implicates the field occupied by federal law.
Based on the pervasive federal regulations concerning flight attendant and crew member training and the aviation safety concerns involved when regulating an airline’s alcoholic beverage service, we conclude that NMLCA’s application to an airline implicates the field of airline safety that Congress intended federal law to regulate exclusively. Thus, New Mexico’s regulatory efforts are impliedly preempted.
B. Twenty-first Amendment
While we conclude that federal law preempts NMLCA’s regulation of the alcoholic beverage service on aircraft, our analysis does not end there. We must next evaluate whether § 2 of the Twenty-first Amendment permits New Mexico’s regulatory scheme, as applied to an airline’s alcoholic beverage service, to override federal policy.
See Capital Cities Cable, Inc. v. Crisp,
1.
Section 2 of the Twenty-first Amendment provides: “The transportation or importation into any State, ... for delivery or use therein of intoxicating liquors, in violation of the laws thereof, is hereby prohibited.” U.S. Const, amend. XXI, § 2. “Notwithstanding the [Twenty-first] Amendment’s broad grant of power to the States, ... the Federal Government plainly retains authority under the Commerce Clause to regulate even interstate commerce in liquor.”
Crisp,
The Supreme Court has recognized that “there is no bright line between federal and state powers over liquor.”
Cal. Retail Liquor Dealers Ass’n v. Midcal Aluminum, Inc.,
New Mexico contends that Twenty-first Amendment balancing is inapplicable in this case. Specifically, New Mexico argues that cases “involving core powers of licensing do not require balancing under the Twenty-first Amendment.” Aplee. Br. at 41. While NMLCA represents an exercise of a state’s core powers reserved by the Twenty-first Amendment,
see Crisp,
In fact, in
North Dakota v. United States,
the state regulations at issue “f[e]ll within the core of the State’s power under the Twenty-first Amendment.”
New Mexico also contends that the Twenty-first Amendment analysis is controlled by
National Railroad Passenger Corp. v. Miller,
Further, the Twenty-first Amendment analysis in
Miller
is inconsistent with more recent Supreme Court decisions. Specifically, the
Miller
court reasoned that “a state has the right to legislate concerning intoxicants brought from without the State for use and sale therein, unfettered by the commerce clause.”
Id.
at 1327. However, the Supreme Court has subsequently stated that “there is no bright line between federal and state powers over liquor,” endorsing the use of a balancing of the state and federal interests involved.
Midcal,
2.
While we defer to the district court to conduct the balancing of state and federal interests in the first instance, we
*1331
offer some guidance for this analysis. The key inquiry in balancing state and federal interests is “whether the interests implicated by a state regulation are so closely related to the powers reserved by the Twenty-first Amendment that the regulation may prevail, notwithstanding that its requirements directly conflict with express federal policies.”
Crisp,
In conducting this balancing, the court should be guided by the following three-step framework:
First, the court should examine the expressed state interest and the closeness of that interest to those protected by the Twenty-first Amendment.... Second, the court should examine whether, and to what extent, the regulatory scheme serves its stated purpose.... Simply put, is the scheme effective? ... [T]he answer to this question may ultimately rest upon findings and conclusions having a large factual component. Finally, the court should balance the state’s interest ... (to the extent that interest is actually furthered by the regulatory scheme) against the federal interest....
TFWS, Inc. v. Schaefer,
In this case, the district court never conducted any balancing of state and federal interests. Thus, the district court did not have the opportunity to evaluate the effectiveness of New Mexico’s regulatory scheme in furtherance of its interests protected under the Twenty-first Amendment. As this inquiry may ultimately depend upon factual findings and conclusions, we remand this case to the district court to conduct the balancing of state and federal interests.
See Miller v. Hedlund,
The district court’s order granting summary judgment for New Mexico is REVERSED and the case is REMANDED for the district court to conduct a balancing of state and federal interests. In further response to the parties’ joint motion to withdraw their motions to seal their briefs, which we have granted, Volume III of the Appellant’s Appendix will remain sealed.
Notes
. However, while concluding that federal regulation occupies the field of aviation safety to the exclusion of state regulation, some circuits have narrowed the field of air safety.
See Elassaad v. Independence Air, Inc.,
. Section 121.575 provides in full:
(a) No person may drink any alcoholic beverage aboard an aircraft unless the certifi *1328 cate holder operating the aircraft has served that beverage to him.
(b) No certificate holder may serve any alcoholic beverage to any person aboard any of its aircraft who—
(1) Appears to be intoxicated;
(2) Is escorting a person or being escorted ...; or
(3) Has a deadly or dangerous weapon accessible to him while aboard the aircraft. ...
te) No certificate holder may allow any person to board any of its aircraft if that person appears to be intoxicated.
(d) Each certificate holder shall, within five days after the incident, report to the Administrator the refusal of any person to comply with paragraph (a) of this section, or of any disturbance caused by a person who appears to be intoxicated aboard any of its aircraft.
