About the Beech 1900/C-12J

The Beechcraft 1900D is a pressurized twin-turboprop commuter airliner that became the workhorse of regional aviation across North America from the early 1990s onward. Developed as a stretched, stand-up-cabin variant of the original 1900, the 1900D introduced a distinctive raised roofline that allowed passengers to walk upright in the aisle, a rare luxury in 19-seat commuters and a major selling point for airlines operating short-haul routes in Alaska, the Canadian Arctic, and the rural United States. Powered by two Pratt & Whitney Canada PT6A-67D engines producing 1,279 shaft horsepower each, the aircraft cruises at around 280 knots and can operate from short, unpaved strips while maintaining cabin pressurization up to 25,000 feet, making it ideal for mountainous terrain and harsh climates where larger jets cannot venture.

Beechcraft delivered over 300 examples of the 1900D between 1991 and 2002, and the type remains in widespread service with cargo operators, charter companies, and a handful of scheduled passenger carriers. Its rugged landing gear, large cargo door, and ability to carry nearly 4,500 pounds of payload have kept it relevant in freight and medical evacuation roles long after most passenger airlines transitioned to regional jets. The 1900D's handling characteristics are straightforward for pilots transitioning from smaller twins, though its long fuselage and relatively narrow track demand attention during crosswind landings. Maximum operating speed is 266 knots indicated, with approach speeds typically around 110 knots depending on weight and configuration.
