PI-C434 Scottish Aviation Twin Pioneer
PAL used Twin Pins along with their Otters on their "Rural
Air Services" routes. They had them
re-engined with Pratt
& Whitney R-1340s in place of the original Alvis Leonides.
Not a good idea.
In the event the Twin
Pioneers were operated for less than two years, and were then sold to
CIA operated phantom
airline in Laos known as Continental Air Services Inc (CASI). In
this one never ever flew
with PAL but went directly to CASI as XW-PDP where it was lost in the
1960s on a covert operation
during the Viet Nam War.
