Dassault Aviation has appointed Thierry Betbeze the new CEO of Dassault Falcon Jet, its U.S. business aviation subsidiary. He will replace John Rosanvallon, who is stepping down after a 44-year career with the French OEM.

Rosanvallon, who will serve as special senior advisor to Dassault Aviation chairman and CEO Eric Trappier during a transition period, led DFJ for the past 23 years from its Teterboro Airport base in New Jersey. In the role, he headed sales, marketing, and support activities for the Americas, successfully growing the Falcon fleet and brand recognition.

“John has built a record of success for the Falcon Jet business and our industry,” said Trappier. “We are pleased we can continue tapping into the wealth of business jet market experience he has accumulated to help improve and expand the Falcon line in the future.”

Betbeze, who has been senior v-p of finance at DFJ since 2016, began his career at Dassault Aviation in 1984 as a cost accountant. He switched to export financing with responsibilities that included treasury and currency hedging before being promoted to senior v-p of finance in 2004.

“Thierry’s appointment is the latest in a number of recent changes intended to reinforce our worldwide sales, marketing, and customer-support effort," said Trappier. "His extensive experience in international finance…will ensure the enduring success of the Falcon brand in today’s demanding business aviation environment.”

Rosanvallon joined Dassault Aviation in 1975 and four years later moved over to DFJ in Teterboro as assistant to the president. After 11 years back in France serving in various executive capacities within Dassault Aviation, he returned to Teterboro as senior v-p of sales and marketing with a mandate to consolidate worldwide Falcon commercial activities. He was appointed CEO of DFJ in 1996.
