Darren Fronk has joined Constant Aviation as operational manager at its Cleveland facility. Fronk, most recently regional sales manager for Stevens Aviation, has 20 years of aviation experience. He is a licensed A&P mechanic with experience as a maintenance duty manager, lead technician, warranty analyst and maintenance controller. The MRO recently added a 20,000-sq-ft hangar dedicated to small and midsize aircraft. “Darren’s experience fell right in line for the management of all day-to-day operations and staff at the new facility,” said Dave Bowman, vice president of operations.
