Narrative:
4 mi outside FAF on approach level 4000 ft at 180 KTS heard bang that sounded like a bird strike. Second and third bang realized compressor stall was happening on an engine. Had copilot pull out qrc and proceed with checklist. Relief pilot pulled out manual and both proceeded to go through checklists. #1 engine egt started rising and went into red. As I continued on approach I declared an emergency and advised tower we were in process of shutting down an engine. When we pulled back the power on the engine it stabilized at safe levels. Tower called emergency equipment and we proceeded on approach to land with flaps 20 degrees and idle power only on #1 engine. After landing with conditions normal at idle we advised tower that emergency equipment was not needed. We also advised flight attendants to remain seated after touchdown. Crew worked well together and both coplts did an excellent job!
