President George W. Bush signs into law the Century of Aviation Reauthorization Act in November. The bill contains important provisions for general aviation, including authorization of certification of design organizations (CDO), protection from the unauthorized use of type certificates, the return of general aviation operations to Ronald Reagan National Airport in Washington, DC, and a change in responsibility for conducting background checks on aliens seeking flight training from the U.S. Department of Justice to the U.S. Transportation Security Administration.
