Aircraft; Procedure; Human Factors
At the gate; we were told that the right engine had been replaced last night. There was no indication of this in our Sabre paperwork. Maintenance was still working on the airplane after it was taxied to the gate. The maintenance release indicated that we needed to confirm normal engine operation prior to entering ETOPS airspace and send a confirmation code. After liftoff an R ENG HI STAGE EICAS appeared. The checklist was completed; but since this was an abnormal indication; we elected to return. Due to uncertainty about the mechanical problem and the fact that we needed to land overweight; an emergency was declared. Engine replacements ought to be in our flight papers. Had the airplane been test flown; this problem could have been found and fixed before inconveniencing our passengers; who now have to wait six hours for another airplane.
B757 Captain is advised that the right engine had been changed over night and that normal engine operation needed to be confirmed prior to entering ETOPS airspace. After liftoff an R ENG HI STAGE EICAS appears and the crew elects to return to the departure airport for an overweight landing.
