On April 20, 1983, a North Korean Ilyushin Il-62M aircraft plummeted into the Fouta Djallon mountains of Guinea, killing all 23 people aboard. The Soviet-built jet, operated by Air Koryo (the state airline of North Korea), was en route when it struck the remote, mountainous terrain in West Africa. The crash claimed the lives of passengers and crew whose identities were difficult to confirm due to the severity of the impact and the remote location of the wreckage. The accident remained shrouded in limited public information, as was typical for incidents involving North Korean aircraft during the Cold War era.

The Ilyushin Il-62M represented the cutting edge of Soviet aviation technology in the 1960s. When the original Il-62 first flew in 1963, it was the world's largest jet airliner, capable of carrying nearly 200 passengers and crew across intercontinental distances. As a long-range, four-engine narrow-body jetliner, it succeeded the popular turboprop Il-18 and became a mainstay of Soviet and allied airlines throughout the Cold War. The Il-62M variant, introduced in the 1970s, featured improved engines and systems. Air Koryo, which had operated the type since the 1970s, relied on such Soviet aircraft for its limited international connections.

The crash highlighted both the isolation of North Korea's civil aviation sector and the challenges of operating aging Soviet equipment. Air Koryo had minimal contact with Western aviation authorities and limited access to modern maintenance facilities or safety upgrades. The remote crash site in Guinea's mountainous interior complicated rescue and recovery operations. This tragedy was one of several accidents involving North Korean and Soviet aircraft during the Cold War, when limited transparency and communication with international aviation bodies made accident investigation and prevention more difficult than in the Western aviation system.
