On April 15, 2002, Air China flight 129, a Boeing 767-200ER, operated by Air China, en route from Beijing, China to Busan, Korea, crashed on Mt. Dotdae, near Gimhae Airport, Busan. Of the 166 persons on board, 37 persons survived the crash, while 129 occupants were killed. The Korean Aviation Accident Investigation Board (KAAIB) determined that the probable cause of the crash was pilot error due to poor crew resource management and lost situational awareness during the circling approach of the runway. The Chinese investigation team pointed out that the Korean ATC was not fully licensed and mistakenly directed the airliner to descend to a wrong altitude and that the airport did not inform the crew of the weather conditions at the time. A contributing factor was that the airline made all announcements in Chinese and English, while most passengers were Korean.
