Top Eight Questions Customers Have About Aircraft Engines

I travel extensively throughout the Great Lakes Region of the United States visiting Duncan Aviation customers and introducing myself to new prospects. I listen to their needs and answer all their questions. Although they may work for different companies and fly different make/model aircraft, they have the same concerns and questions when it comes to maintaining aircraft.
