Bryan Gibbins Collection: converted to the DHC-8-300 prototype "In this form it was first flown on May 15, 1987"; BAE Heritage: "The Dash 8-300 flew in May 1987".[1]Dash 8 Series 300 Stretch Prototype Makes Its First Flight
The original Dash 8 prototype, rebuilt with an 11 ft 3 in fuselage stretch and 2,380 shp PW123 engines, flew for the first time as the 56-seat Dash 8-300 on 15 May 1987.
- Bryan Gibbins's record of C-GDNK (c/n 001) says the first Dash 8 prototype was converted to the 300 prototype with a 3.43 m fuselage stretch, an extra starboard service door, bigger galley and lavatory, wing-tip extensions and 2,380 shp PW123 turboprops, and first flew in that form on 15 May 1987[1]
- The same airframe was withdrawn from use at Las Vegas in September 1989 and broken up at Van Nuys the following March[1]
- Airways says the Series 300 followed in May 1987 as the first stretch, seating 50 to 56, and that the 200 later combined the -100 fuselage with -300 engines[5]
- BAE Heritage lists the -300 as entering service in 1989 and 267 built; production of the 200 and 300 ended in 2009[2]
- Boeing had bought de Havilland Canada in 1986, so the -300 was developed under Boeing ownership before Bombardier acquired the company in 1992[4]
