[1] On 6 June 1986, the companies agreed to another MoU during the 1986 Hanover ILA air show to start the second phase of feasibility studies.
MBB also signed an MoU at that event with General Electric to determine whether its unducted fan (UDF) propulsion technology could be scaled down to power the MPC 75.
The feasibility study also declared that the General Electric's 42.8-kilonewton thrust (4,360-kilogram-force; 9,620-pound-force) GE38-B5 UDF was the only suitable engine investigated, with a takeoff thrust-specific fuel consumption of 6.8 grams per kilonewton per second (0.240 pounds per pound-force per hour), and a cruise SFC of 14.7 g/(kN⋅s) (0.519 lb/(lbf⋅h)) at Mach 0.8 and 11,000-metre altitude (35,000 ft).
However, at their respective baseline configurations, the 501-M80E had a superior specific fuel burn value of 0.0285 kg per nautical mile per seat, compared with the GE38-B5's 0.0324 kg/nmi/seat.
[5] On 31 October 1988, MBB and CATIC announced that they had founded a joint firm in Hamburg called the MPC-75 GmbH, which would administer all activities related to the aircraft.
[8] The name "MPC" was formed from "MBB" and "People's Republic of China" because the project was a German - Chinese joint venture.
On 13.12.1994 the company was renamed to MPCA Multi Purpose Commuter Aircraft GmbH reflecting the end of the German-Chinese cooperation.
