Duncan continues to strengthen its technical team
John Spevak joined Duncan Aviation in 1990 as a mechanic on the Learjet team. Over the years, he has worked on several airframe maintenance teams. Robert Suarez has also joined, as a market research analyst.
John Spevak is both dedicated and personable.

In response to customers' growing needs for Falcon airframe support, Duncan Aviation has added a new technical position at its Lincoln, Nebraska, headquarters. John Spevak has been hired as a Falcon airframe tech rep, providing troubleshooting and technical support to Falcon customers and Duncan Aviation airframe maintenance teams.

Spevak's passion for aircraft and his 31 years of corporate aviation experience began with a tour of Duncan Aviation while he was still in high school. He went on to pursue this passion at Colorado Aerotech, earning an A&P. He joined Duncan Aviation in 1990 as a mechanic I on the Learjet team. Over the years, he has worked on several airframe maintenance teams, gaining experience on Gulfstream, Falcon, Hawker, Cessna, Astra, JetStar and MU-2 aircraft. He worked hard and advanced from a mechanic I to Falcon airframe team leader. Spevak earned his Private Pilot's Licence and has enjoyed many years of flying during this same time.

“John's dedication, experience and personable nature make him valuable in the growth and support of Duncan Aviation's Falcon programme,” says Jeremy Rangel, manager of airframe service. “Our customers and other airframe technicians have come to trust his technical opinions, calling him in to take the lead during complicated airframe maintenance events.”

Meanwhile Robert Suarez has joined the Duncan Aviation aircraft sales and acquisitions team as market research analyst.

Suarez's responsibilities include tracking Duncan core aircraft markets, creating marketing campaigns and assisting in the consignment, acquisition and sale of aircraft. He looks forward to being a part of a team where he can learn and grow as much as possible to ensure the overall success of the Duncan Aviation's aircraft sales and acquisitions services.

“I get most excited about building internal and external customer relationships while learning the aircraft sales brokerage process from some of business aviation's best brokers,” he says.

Aircraft sales and acquisitions market research team leader Rebekah Williams says that Suarez brings a myriad of skills, expertise and personality to round out the aircraft sales and acquisitions team.

“The increase in our volume, the complexity of our transactions and the robust state of the marketplace have placed even more importance on being able to identify, analyse and respond quickly to opportunities on behalf of our clients,” Williams says. “We are very fortunate to have Robert join the aircraft sales and acquisitions team as his passion, energy and aviation knowledge are the perfect fit for our culture and clients.”

Suarez began his career at Duncan Aviation in 2016 and has since attained significant experience in several capacities within the company. Suarez acquired his Private Pilot's Licence in 2019, is IFR rated and is currently working towards earning his Seaplane rating.

“From learning aircraft systems to general flight operations and characteristics, getting my Private Pilot's Licence was without a doubt one of the most fulfilling things I've done,” Suarez continues. “Having that licence will allow me to connect with our brokers, prospective clients and overall customers in being able to relate and cater to their wants and needs when it comes to acquiring or selling an aircraft.”
