Former technician takes the helm at avionics shop
The retirement of the previous long-standing job holder has left a big gap to fill, but stepping into his shoes is Joshua H Chischilly-Keyonnie, himself an 18-year Duncan Aviation veteran.

US MRO Duncan Aviation has promoted an 18-year-veteran of the company, Joshua H Chischilly-Keyonnie, to the position of manager of its Scottsdale satellite avionics shop in Arizona. Chischilly-Keyonnie is stepping in following the retirement of long-time manager Jim Davis.

“As a team member at the Scottsdale shop since 2001, Josh's transition to manager will be a smooth one,” says manager of satellite operations Matt Nelson. “Josh is capable of maintaining the positive environment at the shop as it continues to provide the high quality service our customers expect from a Duncan Aviation facility.”

After joining the Scottsdale satellite shop as an avionics technician, Chischilly-Keyonnie transitioned to crew leader in 2016.

“In my 18 years at Duncan Aviation I've been able to support our customers, and I've been blessed with the opportunity to be a part of business decisions and technical projects,” he says. “I am sincerely looking forward to working with all of our customers, team members, team leaders and managers to achieve our shared goals as a company and provide the support business aircraft operators need.”

Chischilly-Keyonnie will be only the second manager of this avionics shop. Davis recently retired having spent 31 years of his career opening and growing the Scottsdale shop.

“We were the first tenant in the building, which was the only building on that side of the airport at the time,” says Davis. “There were two of us who opened the shop, and now there are five full-time team members and one part-time. It was great to be a part of a company that treated employees and customers with such high standards. I'm grateful to have been a part of Duncan Aviation for the better part of my aviation career.”

Nelson says Davis is the consummate aviation professional and credits him with the growth and success of the Scottsdale avionics shop. “I have known Jim for 31 years,” he says, “and I'm going to miss him.”
