Lin Liguo (, 1945 - September 13, 1971) was the son of the Chinese Communist military leader Lin Biao and the person in charge of Project 571 Outline, a plotted coup against Mao Zedong. Lin joined the People's Liberation Army Air Force in 1967 and was promoted to the deputy director of the Office of the Air Force Command in 1969. Party documents later released state: "the plane was making for the Soviet Union but was inadequately fueled for such a trip; it also had on board neither navigator nor radio operator. It crashed in Mongolia on September 13, 1971, burning to death all on board.".
