In 1985, the FABF also acquired two ex-Soviet Mi-4 transport helicopters from an unknown supplier, followed by an additional two Mi-4s. The Mi-4s were operated by the FABF until the late 1980s, when they were taken out of service. Five Mi-8/17 transport helicopters were later added to the "Escadrille d'Hélicoptères". While supervising the ceasefire after the Agacher Strip War, an FABF SA.316B Alouette III crashed at Kouni on 14 January 1986, leaving only one SA.316B still in service with the "Escadrille d'Hélicoptères".
