Human error is to blame for a passenger plane crash in Libya in 2010 that killed 103 people, AP quoted civilian aviation officials as saying on Friday. The Afriqiyah Airways plane from South Africa crashed into the desert near Tripoli's airport in May 2010. Most of the passengers were Dutch tourists. A 9-year-old boy was the only survivor. The final report of a two-year investigation, which was released on Friday, confirmed that the plane did not have mechanical failures and did not run out of fuel. It pointed to communication errors and faulty procedures by the flight crew. "The pilots' performance was likely impaired because of fatigue," but that the extent to which this contributed to the crash could not be determined, the aviation authority said. The Libyan authority was assisted in the investigation by U.S. and European experts as well as Airbus, which built the A330-202 plane. -- SPA
