The 1983 Chosonminhang Il-62 crash occurred on 1 July 1983 when an Ilyushin Il-62M being operated by the flag carrier airline of North Korea, Chosonminhang, crashed into mountainous terrain in the West African country of Guinea. All 23 people aboard were killed. The aircraft was flying from Pyongyang with construction cargo and numerous workers ahead of the 1984 Organization of African Unity summit due to take place the following year. It remains the deadliest aviation crash in Guinean history, and was the tenth operational loss of an Il-62 since its introduction.
