AC 900 (690D) JetProp Commander

The model 900, released in 1981, featured continued advancement of the engines and capabilities of the plane. Shaft horsepower increased to 748.3 per engine while landing weight increased almost 1,000 lbs. over previous models to 10,550 lbs. The most important advancement of the model 900 was the interior layout. Without extending the overall length of the fuselage, the cabin interior was lengthened by three feet increasing total cabin volume to 278 square feet. This change gave the model 900 one of the best cabin volume per passenger ratings in its segment. The model 900 and model 1000 were the only two models designed and released under Gulfstream ownership.
