His top priority would be to reorganized the ASC and make it an official, independent government organization in coordination with the Executive Yuan. His second priority would be to conduct investigations of aviation accidents that do not involve major affairs, airplane crashes and passenger mortality within one year and figure out the real cause.^[6]
