## Aviation Safety Council Chairmanship

### Aviation Safety Council Chairmanship appointment

Upon his appointment as Chairman of the [Aviation Safety Council](/source/Aviation_Safety_Council) (ASC), Chang said that he had set a goal of zero aviation accidents. Having served as the Director-General of Civil Aeronautics Administration, he would continue to promote and elevate flight safety with his administrative experience and professional knowledge of flight safety management. His top priority would be to reorganized the ASC and make it an official, independent government organization in coordination with the [Executive Yuan](/source/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]
