We had two dispatches with an inoperative SAARU. One of the actions required was to select the EEC's in ALTN and do a full thrust takeoff. Pretty short takeoff on a 80 minute flight with not too many pax and a 30 knot headwind. The return flight was interesting because we got a overtemp on the EGT around Vr. Obviously that was a separate issue but it was interesting to discover that concerns about the condition of a very expensive engine(after having the EGT circle turn red) turned out to not be a big deal. The plane was flying again quite quickly and because the overtemp was quite small and fairly brief(because the thrust lever was moved aft fairly quickly), the maintenance center guy said that they would have to do a borescope check some time in the next few days.

Anyways, it is 34-21-07-02. A bunch of other stuff has to be operable. The MEL is a bit tricky because it says "NOTE 1: For ENG EEC MODE L or R status or advisory messages displayed, the airplane must also be dispatched using MEL item 73-21-02-02". But this message was not displayed either time at the gate. But it does display after engine start, so best to go to the other MEL before engine start and that is where the EEC's are set to ALTN for the full thrust takeoff. Best to just plan for the full thrust takeoff with both MEL's completed before pushback. Otherwise, you have to go to the second MEL after engine start and then take the time to go through the set-up for max thrust with the engines running.
