Business aviation veteran Dan Burkhart, who joined NBAA in 1998 to create the association’s regional program, will retire from his post as director of regional representatives, effective this Friday. Under Burkhart, this division now has six NBAA regional representatives–along with dozens of regional, state and local groups supported by NBAA–who are “dedicated to advancing the interests of the business aviation industry through the power of local leadership.” Burkhart’s role as program director will be assumed by Stephen Hadley, who will also retain his role as NBAA regional representative for the Southwest, a job he has held since 2006.
