stretched 928 model also continued. However, the 528 ultimately received little interest from the airlines, leading to it being quietly removed from the family plan. Operational history Three prototypes, TAC 01 - TAC 03 (Test aircraft) were built. TAC 01 was completed with equipment, the second prototype was a complete fuselage in an unfinished stage of installation. TAC 03 was just a fuselage for structural tests. It was brought to Dresden before the insolvency of Fairchild Dornier. The auction sold (besides many other things) also the prototypes. The German Aerospace Center (DLR) in Göttingen purchased TAC 01 for €19,000. It was sought for cabin testing, which meant the DLR only required the fuselage. After deciding it was too complicated to remove the wings correctly, they were cut off. Therefore, the fuselage went to the DLR research facilities with "stubby wings" of 6 m span. TAC 02 belongs to Deutsches Technikmuseum Berlin now owns the fuselage. TAC 03 remained in Technik Museum Speyer. Variants All of the variants planned a high degree of commonality, including engine type, and flightdeck, which would have allowed for a common pilot type rating. 728 The 728-100 was to have a passenger capacity of 70 to 85. The 728 had the largest cabin in its class, being 0.51 m wider than the Embraer 170/190, and 0.70 m wider than the CRJ-700) with five-abreast seating. The 200 was planned to have a 3,000 kg (6615 lbs) higher MTOW and a 750 km (400 NM) increase in range. Uprated CF34-8D3 engines were to be used on the 728-200, in place of the CF34-8D1 engines used in the 728-100. 928 Planned to follow the 728 into service, the 928 had a stretched fuselage that would have enabled the aircraft to achieve a passenger capacity of 95 to 110 seats. The first flight was scheduled for late 2003 with entry into service in 2005. The 928 featured an increased wing span and more powerful GE CF-34-10 engines. A 928-100 version, as well as a 928-200 version that had an increased maximum takeoff weight (MTOW), was planned. 1128 The 1128, sometimes referred to as 1128JET, was an envisaged further stretch of the 928 to accommodate roughly 110 to 120 passengers. 528 The 528 was to have a shortened 23.38 m (76 ft 9 in) fuselage length and 15.84 m (52 ft 0 in) cabin length would have followed the 928.
