I was just curious since someone told me that it is the same engine that is on the Canadair Challenger 600. I thought the CL-600 was the only airplane made with that engine, but I was wrong. The CL-600 has the Avco-Lycoming ALF-502-L-2C. That engine has been plagued with problems for that airplane.
Actually, the hot and high performance is quite abysmal. I can remember many a hot summer day out in Denver watching 146's roll down a large portion of the runway and wondering if they were going to make it over the fence. However, it is the only jet aircraft in its weight class that will be able to land and takeoff from Aspen, CO in the middle of the summer.
