If you want to compare fatal hull loss accidents in commercial service between Russian and western aircraft then go ahead but you will find that there are no clear correlations eg. Boeing 727 - 112 losses from 1831 aircraft built = 6.1%. Tupolev 154 - 39 from 1025 = 3.8%. Boeing 747 - 49 from 1418 = 3.5%, Ilyushin 86 - 0 from 108 = 0%. This does not take into account flight hours, there are many more ways of comparing but none are conclusive.
YAK 42D production models built 125 number crashed 6 - 4.8%
Aircraft was never a great performer. It was a Soviet copy of a 727/Trident. Only a 193 airframes were produced of all models including prototypes, compared around a 1000 of the 154 that it was supposed to replace.
