Rosenker to Depart NTSB

After leading the National Transportation Safety Board for four and a half years, Mark V. Rosenker has announced that he will resign his position as acting chairman and member. He submitted his letter of resignation to President Obama on July 21.  He intends to pursue opportunities in the private sector. Rosenker said he will delay his departure until a new chairman and an additional board member are confirmed to ensure a quorum remains at the Safety Board. Rosenker became a member and the vice chairman of the NTSB in March 2003 and became acting chairman two years later. He was sworn in as the 11th chairman of the Safety Board in August 2006, and was renominated by President Bush for a second term as chairman in October 2007.
