Deborah Hersman has been named as the nominee for chairman of the National Transportation Safety Board. She would replace Mark Rosenker, who has been serving as interim chairman since his term expired last August. Hersman has been a member of the NTSB since 2004 and has led the investigations of many high-profile business aviation accidents, including the takeoff overrun crash of a Bombardier Challenger at Teterboro (NJ) Airport in 2005 and a 2008 Maryland State Police EMS helicopter crash. Hersman also led the investigation into the 2006 fatal Comair takeoff crash in Lexington, Kentucky. General aviation leaders praised the selection of Hersman to lead the safety board. NBAA President and Chairman Ed Bolen said, "She knows that our industry has long recognized that safety is Job One, and that we are constantly working to build upon our already strong safety record. Debbie has always had an open door for NBAA and its members."
