Oct. 21, 2009, NBAA, Orlando – Conklin & de Decker is celebrating their 25th anniversary in business at the NBAA Annual Meeting and Convention in Orlando, Florida, October 20-22, 2009.

“It’s hard to believe this all began in 1984,” commented Bill de Decker, President and co-founder of Conklin & de Decker. “We were somewhat surprised by our early success and honored by the way the business aviation market now refers to our cost numbers as the industry standard. It is humbling to see where we are today and the broad base of clients that use our data to successfully run their operation every day,” added de Decker.

Alan Conklin retired from his sales position at Dassault Falcon in 1984 and took with him the model for calculating aircraft operating costs that he and Bill de Decker developed for Falcon Jet in 1971. Conklin developed the first Aircraft Cost Evaluator program during the summer of 1984, started marketing it at the 1984 NBAA convention and a new business was born as Al Conklin & Associates.

Bill de Decker had worked closely with Al Conklin at Dassault and after a successful career with FlightSafety International, Bill joined Al in 1989 and the Conklin & de Decker partnership was created.


Alan Conklin’s extensive aviation career spanned more than six decades and began in the US Army Air Corps and US Air Force where he logged thousands of flight hours. He authored God is My Instructor Pilot and co-authored the Aircraft Acquisition Planning book with Bill de Decker He retired from Conklin & de Decker in 2003 and died in November 2006. 

Bill de Decker remains as President of Conklin & de Decker and leads the company with four product lines, consulting services and numerous seminars conducted each year that focus on taxes and the cost of operating business aircraft today. Bill began his aviation career in 1962 as a design engineer on the Apollo moon landing program followed by a stint at Boeing doing design work and cost analysis on various helicopter programs.  He now celebrates 20 years with Conklin & de Decker and the business has grown to include three additional partners, David Wyndham, Brandon Battles and Nel Stubbs that serve as Vice Presidents of the company.
