Hartzell Engine Tech has acquired the assets of Kelly Aero, a manufacturer of aftermarket aircraft magnetos, replacement parts and ignition harnesses for general aviation and military applications.

"With this acquisition, Hartzell Engine Tech is excited to add manufacturing capabilities for aircraft ignition products to our existing lines of engineered, firewall forward, engine accessories," says president Keith Bagley. "We extend our appreciation to Jeffrey Kelly, his family and Neil Clark for creating and stewarding a great product line that will integrate nicely with Hartzell Aviation's 'Built on Honor' philosophy."

Beginning in early 2024, and after a thorough technical evaluation and receipt of PMA approval, Hartzell will rebrand the newly acquired products as PowerUp Ignition Systems. This will be the largest operation in Hartzell’s product portfolio, joining Janitrol Aero, Fuelcraft, Plane-Power, Sky-Tec and AeroForce Turbocharger Systems, and will be incorporated within its main Montgomery manufacturing facility. Hartzell's total workforce will increase by about 40 employees as a result of the acquisition.

Kelly Aero’s former facility will be used to expand the capacity of Hartzell's existing machine shop. The customer direct magneto service work will be accomplished at Quality Aircraft Accessories, a sister company in Tulsa, Oklahoma and Fort Lauderdale, Florida.
