Duncan Aviation has confirmed the promotion of Scott Stoki to Vice President of Engine Operations. A highly experienced professional with a strong technical foundation and many years at the company, Stoki’s elevation reflects Duncan Aviation’s ongoing focus on delivering advanced MRO services and sector-leading expertise to aircraft operators.
Stoki takes over from Doug Alleman, who will retire at the end of the year after 38 years of service. The succession plan ensures operational stability for customers, while leveraging Stoki’s more than two decades of hands-on industry experience to enhance engine reliability and further reduce aircraft time out of service.
Over the past five years, Duncan Aviation’s engine services division has experienced sustained and rapid growth, and in his new role Scott Stoki will seek to build on this trajectory through a series of targeted initiatives aimed at enhancing the customer experience. His priorities include expanding engine maintenance capabilities across appropriate platforms to meet evolving market demand, optimising the company’s 36,000 ft2, Designated Overhaul Facility by reorganising in-house backshop functions such as paint, inspection and test cell operations to reduce turnaround times, and strengthening strategic parts sourcing. Working closely with Duncan Manufacturing Solutions, he also intends to increase in-house component repair capability and refine procurement processes to deliver more cost-effective, efficient support for operators.
Stoki joined Duncan Aviation in 2005 as an Engine Line Technician. Progressing from hands-on work in the hangar to roles in Quality Assurance and later into management, he has developed a comprehensive, end-to-end understanding of the maintenance process. This breadth of experience enables him to translate complex engine technicalities into practical solutions aligned with the strategic needs of flight departments.
“Scott has an unparalleled blend of technical acumen and strategic foresight,” commented Mike Minchow, Duncan Aviation President. “His leadership will be pivotal as we continue to expand our capabilities and deliver the exceptional service our customers have come to expect.”
