Duncan Aviation is expanding its turbine engine capabilities in Lincoln, Nebraska, with a new overhaul center, a significantly larger HTF7000 facility, and an upcoming heavy maintenance service for Honeywell RE100 APUs slated for 2027.
Business aviation service provider Duncan Aviation is scaling up its turbine engine operations through a series of facility expansions and authorization milestones. The developments span several engine platforms, introducing dedicated overhaul lines, expanded square footage, and new technical sales personnel to handle growing demand across the aviation maintenance sector.
Pratt & Whitney Engine Overhaul Center Opens in Lincoln
A new overhaul center dedicated to Pratt & Whitney Canada engines—specifically the PW300 and PW500 models—now features 12 maintenance bays. The facility incorporates dedicated original equipment manufacturer sinks, specialized chemicals, and cleaning processes designed to handle engine subassemblies and major module separations.
To support testing requirements for these powerplants, Duncan Aviation plans to build a new 20,000-pound-thrust Atec test facility. Scott Stoki, VP of engine operations, noted that the company’s existing 20,000-pound-thrust test cell—operational since 2017 for Honeywell TFE731 engines—runs continuously.
Alongside the Pratt & Whitney lines, the updated engine center houses a parts warehouse stocked with 4,362 lines of inventory. Non-destructive testing methods including dye penetrant, eddy current, magnetic particle, and ultrasonic inspection are utilized within the shop to detect cracks and subsurface defects.
Honeywell Facility Expansion and New Sales Expertise
Duncan Aviation recently quadrupled the size of its Honeywell HTF7000 engine shop in Lincoln, Nebraska, bringing the specialized maintenance space to 20,000 square feet under program manager Shawn Schmitz.
The company also extended its service footprint by bringing in Stacy Hollis to join its Turbine Engine Service Sales team. Operating out of Marietta, Georgia, Hollis focuses on business development across the southeastern United States for both scheduled and unscheduled turbine engine services. Hollis brings three decades of aircraft engine experience spanning Honeywell, Pratt & Whitney, and Rolls-Royce platforms.
“Stacy fits perfectly into Duncan Aviation’s Engine Service Sales team. He brings a wealth of knowledge across multiple engine models which not only strengthens our team but diversifies it. Stacy is well-versed in the Honeywell and Pratt & Whitney engines. We are extremely happy to have him join Duncan Aviation.”

Upcoming APU Capabilities and Apprenticeship Support
Beyond turbine overhauls, Duncan Aviation secured authorization from Honeywell to perform RE100 auxiliary power unit (APU) heavy maintenance. The company expects this capability to come online in 2027, adding to its existing authorized repair work for Honeywell HTF7000 engines—which includes 4,800-hour borescope inspections—and its 65-team-member, three-shift TFE731 overhaul operation.
Technical training remains a core component of the operation. The company’s technical education center supports a 20-month AMT apprenticeship program launched in 2020, running two cohorts annually. The facility also aids in onboarding new hires and supports designated mechanic examiner testing for new Federal Aviation Administration mechanics.
