Caribair Convair 640 N3417
In 1965 Caribair began converting its Convair 340s into
Convair 640s by retro-fitting them with
R.Da.10/1 turbo-props. The old orange cheat line was
replaced at that time with
the blue and white livery
seen above. Not one of the more popular conversions, CV640s were
only flown in the U.S.
(originally) by Hawaiian and Caribair. At about that time C.A.B.
was granted permitting
route extensions throughout the West Indies as far afield as Trinidad.
