Ascent Aviation Services has opened two new 90,000-square-foot wide-body maintenance hangars at its Pinal Airpark facility in Marana, Arizona. The $70 million investment more than doubles the site’s total hangar capacity, enabling heavy maintenance, overhauls, and special-mission modifications on Boeing 777, Airbus A330, and other large-jet platforms.
The grand opening, reported on December 12, 2025, follows groundbreaking in April 2024 with an initial estimated cost of $55 million. The expansion supports Ascent’s commercial relationship with Israel Aerospace Industries for Boeing 777-300ER passenger-to-freighter conversions, after the FAA issued the supplemental type certificate in August 2025. Each hangar adds 90,000 square feet, including 180,000 square feet of hangar space and 60,000 square feet of storage and shop areas overall.
The project creates over 300 high-wage aviation jobs, contributing to economic growth in southern Arizona. Joe Snell, president and CEO of the Chamber of Southern Arizona, noted the outstanding regional economic impact. Ascent, a Class IV 14 CFR Part 145 certified repair station, specializes in maintenance for narrow- and wide-body aircraft, including D checks on Boeing 747s.
