Yup. 1978, 9Y-TFO (NS-1, TTDF-2): The then National Security Minister John Donaldson, was being flown to Tobago to view the effects of an oil spill following an oil tanker collision. Officially the aircraft ran out of fuel and was forced to ditch, (but), unofficially, since we all know pilots calculate fuel loads with accuracy and precision, all I have to say is RHIPs. I'm sure you can figure out the rest.......
1994, 9Y-TFN (NS-2, TTDF-3) Another aircraft lost all power on approach to the Chaguaramas heliport, and went down close to the shore line.
I recall 9Y-TFU went down somewhere in the northern range (could be wrong). Status unknown.
1996, 9Y-TGU was sold to a private operator in the US (N7448Y) and and the last known civil registration was SX-HDL (Greece). See photo below:
