Built in 1954 as a CV340 for a corporate customer (as here) and never flew as an airliner. In 2006 it was converted to a water bomber for the Saskatchewan Government and became C-GSKJ. On 14 May 2006, at La Ronge/SK (CYVC), it crashed while flying training circuits after the LH engine autofeathered at low airspeed due to throttle mishandling.

Ex Convair 440 N776. Converted to CV-580 standard in 02.63 and served mainly as a corporate aircraft, latterly with the US Department of Energy as N30EG.

MAAM sold the aircraft to the Government of Saskatchewan and it was registered C-GSKJ and converted to a firefighter. It crashed and was destroyed on May 14, 2006 during a training flight.
