Mark Wilson, chief executive of the British Business and General Aviation Association (BBGA), is set to leave the organization this month to assume a new position as director of regulatory affairs with NetJets Europe. Wilson joined the General Aviation Manufacturers and Traders Association in 2003 and led its merger with the UK’s Business Aircraft Users Association to create BBGA. He has been closely involved in key European lobbying issues, including the contentious debate about whether fractional ownership should be regulated under a new set of quasi-private rules similar to the U.S. Part 91K standards. Along with other fractional providers in Europe, NetJets currently has to operate under commercial JAR-OPS 1 rules.
