Overview of Pinal Airpark in Marana, Arizona

Pinal Airpark in Marana, Arizona, is a county-owned public-use airport in Pinal County, about 30 miles northwest of downtown Tucson along Interstate 10, best known for large-scale commercial aircraft storage, maintenance, and military training in the Sonoran Desert. Often called Pinal County Airpark and widely recognized as an airplane boneyard, it serves aviation professionals, aircraft leasing and maintenance teams, private jet travelers, business executives, and anyone evaluating aircraft storage or private flight access in the Marana-Tucson area.

The surrounding Sonoran Desert environment is central to the airpark’s role. Low humidity, minimal rainfall, and abundant sunshine help limit aircraft corrosion, which makes the site especially well suited for long-term preservation and storage. Across 2,080 acres, Pinal Airpark supports commercial aircraft parking, MRO and parts recovery, military helicopter and parachute training, limited general aviation activity, and a broader regional airport function that matters to operators and travelers who need to understand where private jets can land and access different types of airports in southern Arizona.

Historical Background: From Marana Army Air Field to Modern Air Park

Pinal Airpark was originally Marana Army Air Field in 1942, constructed by Del Webb construction companies and Sundt as part of the U.S. Army Air Forces pilot-training network during World War II. The airfield opened in March 1943 and quickly became a major training base for basic flight training, instrument flying, and multi-engine instruction. Over 10,000 pilots were trained at Marana during WWII, including transport pilots who went on to serve across multiple theaters of the world war.

After World War II ended, the Army closed the field in 1945. Pinal County took ownership of the airfield in 1948 and leased the property to multiple tenants over the following years. The Darr Aeronautical Technical Company reconstructed runways, roads, and buildings during the early 1950s. Through the Cold War era and the Vietnam War period, the airpark saw intelligence-related and defense aviation activity, including operations linked to Intermountain Aviation. Commercial aircraft storage began around 1972.

Evergreen Air Center opened in 1982 for aircraft maintenance, establishing large-scale MRO service at the facility. Pinal County leased portions of the property to Evergreen until 2011, when the maintenance center was sold and renamed Marana Aerospace Solutions. Figures like Jim Petty contributed to the airpark's development and management over the decades. Today, the historic Marana Army Air Field name still appears in local history discussions, though the official designation remains Pinal County Airpark.

Runways, Layout, and Facilities at Pinal County Airpark

Pinal Airpark covers approximately 2,080 acres and has a single primary runway suitable for transport-category aircraft. Key facility details include:

• Runway 12/30: 6,849 feet long by 150 feet wide, asphalt surface, capable of handling narrow-body and some wide-body commercial aircraft under typical conditions

• Aircraft parking: Extensive aprons and storage pads where Boeing 737, 747, 757, 767, and Airbus A319/A320/A321 airplanes are stored nose-to-tail

• Secure storage: Pinal Airpark has nearly 500 acres of secure aircraft storage managed by on-site operators

• Infrastructure: Maintenance hangars with doors offering maintenance access, parts reclamation areas, fuel facilities, offices, and buildings connected to Interstate 10 via local access roads

• Heliport: Four helipads at the co-located Silverbell Army Heliport (three approximately 100 × 100 feet, one approximately 165 × 165 feet)

Pinal Airpark had 58,200 aircraft operations in 2020, averaging about 159 per day. Roughly 86% were military and 14% general aviation. There is no scheduled commercial passenger service. Pinal County departments are responsible for airport oversight, management, and ongoing development at Pinal County Airpark.

Military Presence: Silverbell Army Heliport and Parachute Training

Pinal Airpark is co-located with the Silverbell Army Heliport, which supports Army National Guard units and serves as the home of the Western Army National Guard Aviation Training Site (WAATS), established in 1986. The airpark supports various military aviation activities through the adjacent heliport.

• WAATS training: WAATS provides training for the UH-72A Lakota helicopter and previously operated AH-64 Apache flight and maintenance courses. WAATS discontinued AH-64 Apache training in 2012 as Army aviation requirements evolved.

• Units: The Arizona Army National Guard's 1-285th Aviation Regiment ("Desert Hawks") and related units have operated from Silverbell, along with international partner programs such as Singapore's Peace Vanguard initiative.

• USSOCOM facility: The U.S. Special Operations Command acquired 480 acres in 1992 to establish a parachute training and testing facility west of the runway. Pinal Airpark hosts this facility, which is used for advanced parachute operations, equipment testing, and evaluation in Arizona's stable weather conditions.

Commercial Aircraft Storage, Maintenance, and Ascent Aviation Services

Pinal Airpark serves as a boneyard for civilian commercial aircraft and is one of the most recognizable aircraft storage sites in the country, with parked airliners visible from nearby Interstate 10. It also serves as a global lifecycle hub for managing aircraft at the end of their service.

The dry climate of the Sonoran desert is ideal for aircraft storage. The desert climate significantly reduces aircraft corrosion, which preserves resale value and keeps reactivation costs lower than at humid coastal locations.

Ascent Aviation Services is the main tenant, operating a 500-acre facility at the airpark. Ascent Aviation provides:

• Heavy aircraft maintenance, painting, and modifications

• Long-term storage and preservation (fuel draining, protective coverings, periodic engine runs)

• Aircraft dismantling and parts reclamation (typically 70–100 aircraft per year)

• Boeing 777 passenger-to-freighter conversion work

The airpark has hosted fleets from major U.S. and international airlines. About 38 Delta airliners are parked at Pinal Airpark, alongside aircraft from other carriers. Pinal Airpark experienced significant storage activity during 2020–2021 when the COVID-19 pandemic forced airlines to ground large portions of their fleets. While the facility is sometimes called an abandoned jet yard, many stored airplanes are temporarily parked rather than scrapped, with a portion returning to active service after market conditions improve.

Regional Context: Pinal County, Marana, and Nearby San Manuel Airport

Pinal Airpark sits near the Pinal–Pima county line, close to the growing town of Marana and the greater Tucson metropolitan area in southern Arizona. Ground access is straightforward via Interstate 10, with downtown Tucson roughly 30 miles to the southeast and Phoenix Sky Harbor approximately 100 miles north, fitting the broader pattern described in resources on where private jets typically land and operate.

• San Manuel Airport (E77): A smaller public-use general aviation airport located in the town of San Manuel, north of Pinal Airpark, with a single paved runway serving light aircraft and local traffic. It functions as a reliever airport for the region.

• Two airports, different roles: San Manuel Airport serves as a local GA field, while Pinal Airpark is a specialized facility for storage, maintenance, and military training. The distance between them reinforces the diversity of aviation infrastructure across the county.

• Economic impact: The airpark drives employment in maintenance, logistics, security, and aviation support throughout Pinal County. These jobs help diversify the local economy beyond mining, agriculture, and residential development. Marana Air Park's operations support local suppliers, ground service companies, and fuel providers across the region.

Frequently Asked Questions about Pinal Airpark

Can the general public visit or tour Pinal Airpark?

Pinal Airpark is a secure operational facility with both commercial and military activity, so access beyond the entrance gate is restricted. There are no regular public tours. Organized visits may occasionally be arranged through airport management or tenants like Ascent Aviation Services, subject to security rules.
