Duncan Aviation is nearing completion on a 36,000-square-foot Pratt & Whitney Canada Designated Overhaul Facility (DOF) in Lincoln, Nebraska for PW300 and PW500 turbofan engines. The project marks a major expansion of the company’s turbine engine capabilities and aims to deliver faster, more efficient service to customers.

Designed by Tectonic Management Group and constructed by Hausmann Construction, the new facility is fully enclosed and progressing with interior fit-out. It includes twelve engine maintenance bays, expanded backshops with advanced tooling, a parts inventory warehouse, and modern customer and employee areas.

Sixteen overhead cranes have been installed to improve precision and safety when handling large components, while infrastructure upgrades include a larger evaporator drain pit and a 12,000-gallon fuel tank with backup systems to ensure continuous test cell operations.

The addition will feature a new test cell and control room from Atec, Inc., designed for quieter and more efficient testing. The DOF is expected to begin operations in November 2025, with overall project completion set for April 2026.

“These comprehensive in-house capabilities underscore our unwavering commitment to providing unparalleled, cost-effective and high-quality engine maintenance services,” says Doug Alleman, vice president of Duncan Aviation’s engine operation. “We are dedicated to maximising aircraft performance, minimising downtime and ensuring the long-term value of our customers’ investments.”
