Mark Van Tine, the long-time CEO of Jeppesen and vice president of digital aviation at parent company Boeing, is retiring on June 30 after a more than 35-year career with the company. Succeeding Van Tine in those roles is Kevin Crowley, who has been vice president of technology development at Boeing.

Van Tine had spent 14 years as CEO of Jeppesen and 16 years as a Boeing executive. During that time he helped in the transition of Jeppesen from paper charts to a digital format. Van Tine began his career in 1981 with flight planning and weather specialist Lockheed DataPlan, which Jeppesen acquired in 1989. He relocated to Denver in 1995 to oversee Jeppesen’s worldwide flight information development, printing and distribution operations and IT organizations. He later became chief information officer and then CEO in 2002. He also has been actively involved in aviation issues, serving as a past chairman of the General Aviation Manufacturers Association and on the board of the Experimental Aircraft Association.

Crowley has served with Boeing since 1989, beginning as a software engineer. He has held a number of positions with Boeing Commercial Airplanes and Defense and Space engineering. Before becoming vice president of  technology development, he was vice president of 787 partnering for success integration in the Boeing Commercial Airplanes supplier management organization.
