Note. Several reports indicate the plane crashed on May 21 or May 22 near Zumba, Ecuador. Other reports suggest that the Twin Otter crashed while flying in formation with the Presidential Beechcraft 200 on May 24, 1981. This accident happened near Macará, Ecuador, killing Ecuadorian President Jaime Roldós Aguilera aboard the Beech 200. Newspaper reported at the time do however not report the simultaneous accident of the Twin Otter. It is thus considered probable that the Twin Otter crashed in a separate accident a few days earlier.
