Tiffin Aire, Inc is located at the Seneca County Airport (K16G) in Northwest Ohio. Seneca County Airport offers a 4000’ runway with parallel taxiway as well as GPS, VOR, and NDB approaches.

Lodging, food and entertainment are just minutes from the airport. Tiffin Aire, Inc offers courtesy cars, catering and 24 hour self-service fuel.


Based at the Seneca County Airport, Tiffin Aire Inc. was founded in 1968 by Dwight and Jeanne Gnepper. It began with only three employees, two single engine aircraft, two hangars, and an office. In 1989, after many years of growth and expansion, the Gneppers retired and sold Tiffin Aire to their daughter and son-in-law, Brad and Kim Newman.

By 1996 Tiffin Aire offered aircraft charter, flight instruction and rental, aircraft sales, aircraft maintenance, parts and oil sales, and propeller/governor sales and service. De-ice boot sales/installation and the Tiffin Aire Tug were added to the company product line in later years.

With son Andrew Newman joining the company, Tiffin Aire is now in its third generation of family. We take great pride in being a family owned and operated business!
