Russian officials plan to resume production of the An-2 — a light “corn duster” aircraft designed in the 1940s — after years of failed attempts to develop a replacement for the Soviet biplane. Previously, officials tried to fill the gap by certifying the Il-114-300, but that aircraft turned out to be completely unfit for real-world operation — in addition to being too expensive for customers. As for the flagship projects MC-21 and SJ-100, even if they can be certified and put into production, they risk ending up as commercial failures.
