Incident: Minstrel Island, BC, 01-Aug-2001. The float-equipped aircraft had landed at Minstrel Island and was taxiing to the dock when the pilot of a company aircraft that was following C-GNWS to the dock radioed that he saw smoke coming from the lower right area of C-GNWS's engine cowling. The pilot of C-GNWS docked the aircraft, unloaded the three passengers and emptied a fire extinguisher onto the burning aircraft. The fire was not extinguished and the aircraft was pushed away from the dock where it burnt to the water.CADORS report 2001P0638
