In 2000, Williams joined with Eclipse Aviation to develop an FAA-certified version of the FJX-2, designated the\u00a0Williams EJ-22, to be used on the Eclipse 500<\/a> VLJ due for first flight in June 2002. <\/p>\n\n\n\n

This would be an unprecedentedly short period of time to develop a new man-rated turbofan engine. <\/p>\n\n\n\n

The new EJ22 powered the Eclipse 500 prototype on its first flight in the Summer of 2002.<\/p>\n\n\n\n

Eclipse initially required the engine to produce 770 lbf thrust, exceeding the 700 lbf rating of the FJX-2 by 10%. This was only the first of a large number of continuously changing requirements Eclipse would demand. Ultimately, numerous technical problems with the EJ22, significantly compounded by the frequently changing requirements of Eclipse Aviation, grounded the plane and prompted Eclipse Aviation to terminate its relationship with Williams International in late 2002.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Following termination of the contract, development work was halted shortly thereafter and the engine never came close to FAA certification<\/p>\n\n\n\n
