After use as a Twin Otter Series 300 and water bomber demonstrator, CF-YFT was leased to White River Air Service for NorOntair flights September 20, - October 30, 1971. Flown without titles in the DHC house colors, the aircraft was returned and delivered to Bell Canada in December 1971. Sold to Trigana Air Services, (PK-YPF) in February 1993. After written off in a landing accident, the remaines were sold to SSC International. Although allotted registration N60619, I haven't found any information that the aircraft was actually rebuilt.
