I'd be pretty sure the GE deal came around as part of Air Asia buying engines for their fleet from GE Aviation, however you are quite right in saying GEs portfolio is very diverse. The healthcare equipment could be used but I wouldn't be surprised if GE make/have experience of similar kit for engineering disciplines. They make and service aero engines, locomotives, gas turbines, nuclear reactors even.
GE also have lots of experience with composites and their manufacture.
