Airforce Turbine Service (ATS) has appointed Randy Mengel as chief executive officer and Isaias Gomez as chief financial officer, effective immediately, as the Texan aviation services company expands its international PT6A MRO capabilities.

The appointments follow McNally Capital’s acquisition of ATS in December 2025. Mengel brings more than 35 years of aerospace and defence experience, most recently serving as senior vice president of Regional One’s engine division. Before that, as chief operating officer of CTS Engines, he launched GP7200 and F117 MRO programmes supporting the Airbus A380 and C-17 Globemaster III respectively.

During 12 years at StandardAero, Mengel doubled revenue at its Maryville operations, expanded shop capabilities and led engine programmes including the Rolls-Royce AE-1107 and AE-2100, supporting the V-22 Osprey and C-130J.

Mengel says: “ATS has built a strong reputation as a trusted partner to PT6A operators around the world, and I am excited to join the company at such a pivotal point in its growth journey. The team has done tremendous work expanding the global capabilities and footprint, and I look forward to building on that foundation and deepening our operational excellence, growing our aftermarket platform and continuing to deliver the reliability our customers depend on.”

Gomez brings more than 25 years of finance leadership across aerospace, aviation MRO and international operations. Most recently, he served as chief financial officer of Citadel Completions, partnering with the CEO on strategy, capital allocation and organic growth and helping integrate several strategic acquisitions.

Gomez says: “I am excited to join ATS and work alongside Randy and the broader leadership team, and I look forward to bringing financial discipline and strategic focus to support the company’s continued organic and inorganic growth initiatives.”

Mengel and Gomez will work closely with ATS executive chairman Rob Wilson and the company’s existing leadership team. Wilson has served as interim CEO and executive chairman since McNally’s acquisition of ATS and will remain executive chairman. He is the former president of business aviation and general aviation at Honeywell Aerospace.

Wilson says: “Randy and Isaias are the right leaders to help take the business to the next level. Their deep operational and financial expertise will strengthen ATS as the company expands the global footprint of this leading platform for PT6 MRO services and builds on the deep expertise and execution culture of its team across all three locations.”

ATS offers PT6A overhaul, maintenance and AOG field repair, with its global footprint anchored by its PT6A centre of excellence in Mathis, Texas. It also has maintenance centres in Malaysia and South Africa and a sales office in Guatemala.
