Gregory Polek has spent his entire career in aviation journalism with AIN, starting as a proofreader and assistant to then-managing editor Mary Mahoney in 1995 after serving an internship with&nbsp;New Jersey Monthly&nbsp;magazine and completing his B.A. degree in English/Writing at New Jersey’s William Paterson College. By 1997 Polek accepted a position as an associate editor, covering the regional airline beat for&nbsp;Aviation International News&nbsp;in place of retiring industry veteran Don Anderson. The assignment took Polek across North America and Europe to profile regional airlines varying in size and mission from the likes of floatplane operators Kenmore Air and Chalk’s Ocean Airways to regional jet operators such as SkyWest and American Eagle. Today, in his dual role as Air Transport Editor and International Airshow Editor, Polek writes, edits, and manages AIN’s commercial aviation content while overseeing each of the company’s daily international air show publications in Paris, Farnborough, Singapore, and Dubai. Most recently Polek has assumed oversight of daily coverage of the Helicopter Association International’s annual Heli-Expo convention.

Duncan Aviation has carried out leadership changes at its Turbine Engine Services business in Lincoln, Nebraska, naming Scott Stoki, Brad Wales, and Tyler Spurling managers of engine services for Pratt &amp; Whitney Canada (P&amp;WC), Honeywell, and line services, respectively. The company’s engine overhaul services business has experienced significant growth since 2015, when it extended its Honeywell service authorization to include HTF7000 turbofans. It also earned designation as a&nbsp;Honeywell TFE731 heavy maintenance facility in 2017.
Most recently, Duncan Aviation announced during NBAA-BACE 2023 that P&amp;WC named Duncan Aviation’s MRO facility in Lincoln as a designated overhaul facility for PW300 and PW500 engines. In the third quarter, Duncan plans to break ground &nbsp;on a 36,000-sq-ft powerplant overhaul facility featuring 12 engine maintenance bays, dedicated storage racks, a parts inventory warehouse, and an expanded back shop area.
Stoki joined Duncan Aviation as an engine line technician in 2005 and moved to the quality department as an inspector. He returned to engine services in 2019 to manage the Honeywell engine overhaul shop. With the DOF announcement, Stoki assumes leadership of P&amp;WC overhaul capabilities, where he identifies and purchases advanced machinery, plans for shop safety enhancements, and guides team member training and growth.
Wales, who now serves as manager of engine services for Honeywell engines, started his career at Duncan Aviation in 2015 as a technician in the engine line shop. He quickly progressed through the ranks and became a project manager before returning to the engine line shop as the manager. His move to the position of manager of Duncan Aviation’s Honeywell overhaul services gives him day-to-day leadership over the company’s 40,000-sq-ft Honeywell engine complex, which features TFE731 Series Heavy and HTF700 Series minor authorization services.
Manager of engine line services Spurling joined Duncan Aviation in 2007, beginning as a technician in the engine line shop. Within six years, he became a team leader and in 2016 took over an engine rapid response team (RRT).
In 2019, he took over the Lincoln MRO airframe and engine RRT, eventually consolidating the mobile airframe AOG and inspection services based at Duncan Aviation’s three MRO locations in Battle Creek, Michigan; Lincoln; and Provo, Utah. He served as manager of MRO RRT for three years before returning to the shop, where Duncan originally hired him as manager of engine line services.
Engine Line Services has a dedicated 4,050-sq-ft shop just off one of Duncan Aviation’s 40,000-sq-ft maintenance hangars, where technicians tear down and rebuild engines free from aircraft moves and unnecessary interruptions.&nbsp;
Thirty-five years ago, v-p of engine services Doug Alleman joined Duncan Aviation as an A&amp;P mechanic in the engine shop. He has witnessed firsthand the growth and expansion of the company’s engine capabilities and shop facilities.&nbsp;“The rapid expansion of our turbine engine overhaul services underscores our commitment to our OEM partners, including Honeywell, Pratt &amp; Whitney Canada, their engines, and mutual customers,” said Alleman.
“Nearly 63 percent of the engines sent in for inspection, repair, and overhaul are shipped in from aircraft located at airports worldwide. Our engine RRT network will be vital in supporting the increased business,” he concluded.
