President Barack Obama will nominate veteran pilot and aviation safety expert Christopher A. Hart to be a member of the National Transportation Safety Board (NTSB). Hart, who previously served on the board from 1990 to 1993, has been working at the FAA since 1995 to create processes to help identify and address potential safety issues before they cause mishaps. An attorney, Hart also has degrees in aerospace engineering and is an experienced pilot with a commercial certificate and multi-engine and instrument ratings. He previously served as a deputy assistant general counsel at the U.S. Department of Transportation and was a lawyer at the Air Transport Association. Hart replaces Steven R. Chealander who resigned this past February to take a senior executive position at Airbus.
