De Havilland Canada DHC-8-300 Dash 8
The DHC-8-300 stretched the Dash 8 family by 3.4 m over the -100/-200, raising typical seating from around 39 to 50-56 passengers while keeping the same high-T-tail, twin-turboprop layout. It uses Pratt & Whitney PW123 series engines rated up to roughly 2,500 shp in the later 300B/300E subvariants, giving cruise speeds near 287 knots. The stretch made it a genuine regional airliner rather than a commuter feeder, and it stayed in production after the -100 was discontinued. Many -300s remain in scheduled service with regional carriers worldwide.

The stretched Dash 8-300 gained enough extra cabin length to serve busier regional routes without needing a full-size regional jet.
