I read some time ago, that NW and CO was planning on fitting RR Tays to their DC9 and MD80 fleets as part of conversion to fuel efficiency. Now as we can see it has not happened, but I do not know what happened to the plans. I know NW has retired its MD80s, I know that CO has retired the DC9s, and they are retiring their MD-80s. Is NW still planning on converting the engines to TAYS or BR710s or are they just going to keep the JT8D engines.
BTW -- I read this in a Monthly Employee Newsletter in December 1998/January 1999 for NW
