Conklin & de Decker will now be recognized as a JSSI company, retaining the name that was created by founders William ‘Bill’ de Decker and the late Alan H. Conklin in 1984. The Conklin & de Decker collection of products and services include its flagship cost comparison tool, Aircraft Cost Evaluator; the Life Cycle Cost budgeting program; the Aircraft Performance Comparator; MxManager for maintenance tracking; and the State Tax Guide planning tool. In addition, they offer aircraft acquisition, fleet planning, finance, and tax consulting services, as well as educational seminars focused on aircraft acquisition, operating cost, and tax planning.

Bill de Decker, co-founder of Conklin & de Decker commented, “Our companies have many similarities, and all of us at Conklin & de Decker look forward to building on our synergies, especially our dedication to a service-based culture. We have worked very closely with the JSSI team since its inception in 1989, and now we are very proud to be a part of this successful and innovative company.”
