Duncan Aviation has made leadership changes to its turbine engine services in Lincoln, Nebraska. Scott Stoki, Brad Wales and Tyler Spurling have been named managers of engine services for Pratt & Whitney, Honeywell and line services, respectively.

Duncan's engine overhaul services unit has experienced significant growth since 2015 as the company's Honeywell service authorisation was extended to include HTF7000 (AS907) series minor and then again in 2017, with the designation as a Honeywell TFE731 heavy maintenance facility.

Most recently, its MRO facility in Lincoln was made a DOF (Designated Overhaul Facility) for PW300 and PW500 turbofan engines.

In 2005, Stoki joined Duncan as an engine line technician, where he demonstrated his natural leadership abilities, taking on positions with more responsibilities. He then transitioned into the quality department as an inspector, gaining a new appreciation for detailed paperwork. He returned to engine services in 2019 to manage the Honeywell engine overhaul shop.

With the new DOF announcement, Stoki shifted his focus and has assumed leadership of P&WC overhaul capabilities. He has been instrumental in identifying and purchasing advanced machinery, planning for shop safety enhancements and guiding team member training and growth.

Duncan Aviation will break ground this summer on a 36,000sq ft DOF featuring 12 engine maintenance bays, dedicated storage racks, a new parts inventory warehouse and an expanded backshop area.

Wales started his career at Duncan 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 transition to manager of Honeywell overhaul services gives him day-to-day leadership over the company's 40,000sq ft Honeywell engine complex, which features TFE731 series heavy and HTF700 series minor authorisation services.

In-house engine capabilities such as a clean room, media blasting machines, shot peen equipment, a paint booth, NDT capabilities and a balance room are improving, expanding and centrally located to facilitate maintenance team efficiencies between all OEM-authorised operations.

Since Spurling joined Duncan in 2007, he has worn many hats, beginning as a technician in the engine line shop. Within six years, he became a team leader and again in 2016, leading an engine rapid response team (RRT). In 2019, he took over the LNK MRO airframe and engine RRT, eventually consolidating the mobile airframe AOG and inspection services based at Duncan's three MRO locations in Battle Creek, Michigan; Lincoln, Nebraska; and Provo, Utah. He served as manager of MRO RRT for three years before returning to the shop, where he was originally hired as manager of engine line services.

The engine line services division has a dedicated 4,050sq ft shop just off one of the 40,000sq ft maintenance hangars, where engines are torn down and built up free from aircraft moves and unnecessary interruptions.

Thirty five years ago, Doug Alleman, vice president of engine services, joined the company as an A&P mechanic in the engine shop. He has witnessed first-hand the growth and expansion of the company's engine capabilities and shop facilities and says this growth is a testament to Duncan's more than 30 year relationships with Honeywell and Pratt & Whitney Canada.

"The rapid expansion of our turbine engine overhaul services underscores our commitment to our OEM partners, including Honeywell, Pratt & Whitney, their engines and mutual customers," says Alleman. He goes on to say that with each passing year, the demand for Duncan's engine maintenance services continues to grow. "Nearly 63 per cent of the engines sent in for inspection, repair and overhaul are shipped in from aircraft located at airports worldwide. Our engine RRTs network will be vital in supporting the increased business."

In addition, Duncan Aviation is authorised by GE, Williams International and Rolls Royce to perform a broad spectrum of engine services and inspections.
