Still Canada's best business airplane program with more than 800 manufactured, the Twin Otter stays mainstream for its tough development and valuable STOL execution.

Advancement of the Twin Otter goes once again to January 1964 when De Havilland Canada began configuration deal with another STOL twin turboprop worker carrier (seating somewhere around 13 and 18) and utility transport. The new flying machine was assigned the DHC-6 and model development started in November that year, bringing about the sort's first flight on May 20 1965. In the wake of accepting confirmation in mid 1966, the first Twin Otter entered administration with long time De Havilland Canada supporter the Ontario Department of Lands in Canada.

The principle expansion to the Series 200, which was presented in April 1968, was the broadened nose, which, together with a reconfigured stockpiling compartment in the back lodge, incredibly expanded things stowage range.

The Series 300 was presented from the 231st generation airplane in 1969.
