Introduction
The Fairchild Dornier 328JET represents the final chapter in the storied history of Dornier aircraft production—a modern regional jet that carried the legendary Dornier name into the 21st century. As the jet-powered derivative of the successful Dornier 328 turboprop, the 328JET combined proven design elements with turbofan propulsion to create a fast, efficient regional airliner. Though it would ultimately be the last aircraft to bear the Dornier name in production, the 328JET demonstrated that the company's tradition of innovation and engineering excellence remained vital to the end.
Evolution from the Dornier 328 Turboprop
The 328JET's story begins with the Dornier 328, a 30-seat turboprop regional airliner that entered service in the early 1990s. The original 328 was designed to serve short-haul regional routes with excellent performance, modern systems, and passenger comfort superior to competing turboprops. The aircraft featured a distinctive T-tail configuration, advanced composite materials, and a spacious cabin that set new standards for regional aircraft.
As the 328 turboprop established itself in the market, Dornier recognized an opportunity to create a jet-powered variant that would offer higher cruise speeds while retaining the proven airframe and systems. The jet version would appeal to operators seeking turbofan performance and passenger appeal while benefiting from commonality with the turboprop variant. This strategy of offering both turboprop and jet versions of the same basic airframe would maximize market coverage and operational flexibility.
Design and Development
Development of the 328JET began in the mid-1990s under Fairchild Dornier, the company formed when Fairchild Aircraft acquired Dornier. The jet variant retained the 328's fuselage, wing, and tail design while replacing the turboprop engines with Pratt & Whitney Canada PW306B turbofan engines mounted in pods beneath the wings. This configuration provided the speed and altitude performance of a jet while maintaining the structural and systems commonality that would reduce development costs and operator training requirements.
The 328JET incorporated several refinements beyond the engine change. The wing was strengthened to accommodate the different engine mounting and thrust characteristics. The fuel system was modified for the turbofan engines' requirements. Avionics were updated to take advantage of the latest navigation and flight management technology. The result was an aircraft that shared approximately 90% commonality with the turboprop version while offering significantly different performance characteristics.
Technical Specifications and Performance
The Fairchild Dornier 328JET accommodates 32 passengers in a comfortable 2+1 seating configuration, with the single seats on one side providing a premium option popular with business travelers. The twin PW306B turbofan engines each produce approximately 5,900 pounds of thrust, enabling cruise speeds of around 750 km/h (465 mph)—significantly faster than the turboprop version's 620 km/h. Maximum range exceeds 2,000 kilometers, suitable for most regional routes.
The aircraft's performance envelope includes excellent short-field capability, allowing operations from airports with runways as short as 1,200 meters. Service ceiling of 35,000 feet enables the 328JET to fly above most weather and turbulence, providing smoother rides than lower-flying turboprops. The combination of jet speed, good range, and short-field performance made the 328JET attractive for regional operators serving diverse route networks.
Cabin Comfort and Passenger Appeal
One of the 328JET's strongest selling points was its spacious, comfortable cabin—unusual for a 30-seat regional aircraft. The fuselage cross-section allowed stand-up headroom throughout the cabin, overhead bins for carry-on luggage, and seat pitch comparable to mainline jets. Large windows provided excellent natural light and views. The quiet, smooth operation of the turbofan engines enhanced passenger comfort, particularly compared to turboprop competitors.
The 2+1 seating configuration meant no middle seats—a significant passenger amenity. The single seats on one side were particularly popular with business travelers who valued the privacy and window access. Lavatory facilities, coat closet, and galley provisions allowed full meal and beverage service on longer flights. These comfort features helped airlines market the 328JET as a premium regional service, commanding higher fares than typical regional aircraft.
Market Position and Competition
The 328JET entered a competitive regional jet market dominated by the Bombardier CRJ series and Embraer ERJ family. While these competitors offered larger capacity (50-70 seats), the 328JET targeted a niche for smaller, more comfortable regional jets suitable for thin routes and premium services. The aircraft's superior passenger comfort and short-field performance differentiated it from larger regional jets that required longer runways and offered less spacious cabins.
Airlines operating the 328JET included regional carriers in Europe and North America seeking to offer jet service on routes with modest passenger demand. The aircraft proved particularly successful in mountainous regions and areas with challenging airports where its short-field capability provided operational advantages. Corporate and government operators also acquired 328JETs for VIP transport, valuing the combination of jet performance and comfortable cabin.
