Aeroflot Flight 418 was an international passenger flight operated by a Tupolev Tu-154A, registered CCCP-85102, that was operating the second leg of a scheduled Luanda–Malabo–N'Djamena–Tripoli–Moscow passenger service. The plane crashed on into a mountain near Malabo Airport on Bioko Island, Equatorial Guinea on 1 June 1976.
The aircraft was en route from Quatro de Fevereiro Airport to Malabo International Airport when it struck a mountain high at Bioko, Equatorial Guinea. All 42 passengers and 4 crew perished.
The cause of the accident could not be determined, but the investigation commission suspected a possible failure of the MSRP-12 radar on the aircraft may have led the crew to be unaware of their position.
