The first Soviet Annushka rolled out of production in 1946, that is 71 years ago if you are counting. It's Chinese equivalent, the Y-5 revived its production certification in 1958. That's 59 years ago, again look who's counting right? A total of 140 copies entered service by 1989 according to "China Today: Aviation Industry" by the China Aviation Industry Press.
Judging by this set of recently released PR photos depicting airborne recruits' first jump on Y-5s, at least some of them are still going strong.
