Since 'Mig Eater' hit the Fulcrum with JP233, and since (IIRC) the Buccs arrived after the transition from JP233 to medium level PGM use, then the Bucc 'kill' would have happened later. However, I think that the Cub was firmly on the ground at the time, whereas the MiG was in the process of taking off and may have been in flight when brought down: the Cub, as far as I'm aware, wasn't(?).
