Following the Turkish Airlines Flight 1951 crash , Van Vollenhoven led the investigation by the Safety Board . This investigation brought him into conflict with the Office of the Attorney General , which requested access to the black box data . Citing that there was no reason at that time to suspect foul play and that the Board investigation would be hampered by the threat of legal action against persons , Van Vollenhoven absolutely refused this access
