I don't know if this is of the great importance but I'd like to give some information on the Russian and post-Soviet aircraft.
Tupolev Tu-204 first production aircraft - 17/08/1990
Ilyushin Il-96-300 - first production aircraft - 29/12/1992
Yakovlev Yak-42 - first production aircraft - 1979
Yakovlev Yak-42D - entered service in 1987
Also only Antonovs An-2, An-10, An-14, An-28, An-24, An-38, An-74TK-200, An-74TK-300, An-140 and An-148 were passanger aircraft, while An-26, An-32, An-72, An-74 were cargo planes and were capable of paratroops carriage only, the same refers to Il-76 which is a pure frighter with no passanger options.
