U.S. watchdog auditing FAA checks of Southwest Air after engine failure

The U.S. Transportation Department's inspector general is auditing the Federal Aviation Administration's oversight of Southwest Airlines Co after a midair incident in which an engine exploded and one person was killed. The inspector general said "our objective is to assess FAA’s oversight of Southwest Airlines’ systems for managing risk." The office will write a report after it completes the review and may make recommendations. A Southwest Boeing 737 engine failed in midair on April 17 after it lost a fan blade, killing one passenger.
