Narrative:
On climb out of dca en route to atl we were cleared to FL330. Passing FL315 we heard a loud bang. We checked the engine instruments and saw that #2 EPR was low with a reading of around 1.4, while all other engine indications were normal. Disconnected the autothrottles and retarded the throttle to idle. Initially requested a descent to FL270. Decided to divert to rdu and began our descent for the approach and landing. A couple of times in the descent did feel some momentary vibration. Eventually we did lose oil pressure and oil quantity. At that time we shut down the engine and declared an emergency. Approach and landing at rdu were normal. We taxied to the gate and then found out we had what appeared to be an uncontained engine failure.

Title: THE RPTR EXPERIENCED A LOUD BANG AND LOW EPR ON CLBOUT. ENG VIBRATION ON DSCNT PROMPTED SHUTTING THE ENG DOWN AND DECLARING AN EMER.
Narrative: ON CLBOUT OF DCA ENRTE TO ATL WE WERE CLRED TO FL330. PASSING FL315 WE HEARD A LOUD BANG. WE CHKED THE ENG INSTS AND SAW THAT #2 EPR WAS LOW WITH A READING OF AROUND 1.4, WHILE ALL OTHER ENG INDICATIONS WERE NORMAL. DISCONNECTED THE AUTOTHROTTLES AND RETARDED THE THROTTLE TO IDLE. INITIALLY REQUESTED A DSCNT TO FL270. DECIDED TO DIVERT TO RDU AND BEGAN OUR DSCNT FOR THE APCH AND LNDG. A COUPLE OF TIMES IN THE DSCNT DID FEEL SOME MOMENTARY VIBRATION. EVENTUALLY WE DID LOSE OIL PRESSURE AND OIL QUANTITY. AT THAT TIME WE SHUT DOWN THE ENG AND DECLARED AN EMER. APCH AND LNDG AT RDU WERE NORMAL. WE TAXIED TO THE GATE AND THEN FOUND OUT WE HAD WHAT APPEARED TO BE AN UNCONTAINED ENG FAILURE.
