A U.S. government watchdog is going to audit the Federal Aviation Administration's (FAA) oversight of Boeing (NYSE: BA) manufacturing, a fresh reminder that the dark clouds that have been hanging over the aerospace giant for years have not yet receded. On a down day for markets the news was enough to cause a 5% decline in Boeing's share price Thursday morning. Boeing has been trying to rebuild its reputation and normalize plane production for nearly four years now.
