Narrative:

Just as we began our descent; the right engine compressor stalled and failed immediately thereafter. During first approach; we did not have enough rudder authority to maintain alignment for touchdown; so a single engine missed approach was executed. We landed successfully out of the second approach; but rudder authority was still limited.supplemental information from acn 733027: we declared an emergency with center and received priority vectors. During short approach we drifted too far right for a safe landing; and executed a go around. We then were vectored to the ILS and executed the approach and landing without further incident. Arff met the aircraft as we taxied clear; and verified there were no indications of smoke or fire.callback conversation with reporter revealed the following information: the reporter stated the rudder authority/authorized on approach was limited to one and one half degrees; much less than normal. The reporter alleged the limited rudder authority/authorized compromised the flight crew's ability to align the aircraft with the runway during the crosswind approach; leading to the single engine go around. The reporter stated he is in contact with his air carrier maintenance personnel to attempt to determine the cause of the limited rudder authority/authorized. The reporter stated rudder authority/authorized is limited at cruise speeds; and that limited authority/authorized would have been in effect at the time of the engine shutdown; but the rudder authority/authorized should have increased as the speed was reduced for the approach; but did not do so.

Title: AN MD80 FLT CREW EXPERIENCED A COMPRESSOR STALL AT TOP OF DSCNT; SHUT DOWN THE ENGINE; AND DECLARED AN EMER. ON APCH; THE PF NOTICED LIMITED RUDDER AUTH; WHICH LED TO A SINGLE ENGINE GAR AND SUBSEQUENT SUCCESSFUL LNDG.

Narrative: JUST AS WE BEGAN OUR DSCNT; THE R ENGINE COMPRESSOR STALLED AND FAILED IMMEDIATELY THEREAFTER. DURING FIRST APCH; WE DID NOT HAVE ENOUGH RUDDER AUTHORITY TO MAINTAIN ALIGNMENT FOR TOUCHDOWN; SO A SINGLE ENGINE MISSED APCH WAS EXECUTED. WE LANDED SUCCESSFULLY OUT OF THE SECOND APCH; BUT RUDDER AUTHORITY WAS STILL LIMITED.SUPPLEMENTAL INFO FROM ACN 733027: WE DECLARED AN EMER WITH CTR AND RECEIVED PRIORITY VECTORS. DURING SHORT APCH WE DRIFTED TOO FAR R FOR A SAFE LNDG; AND EXECUTED A GAR. WE THEN WERE VECTORED TO THE ILS AND EXECUTED THE APCH AND LNDG WITHOUT FURTHER INCIDENT. ARFF MET THE ACFT AS WE TAXIED CLR; AND VERIFIED THERE WERE NO INDICATIONS OF SMOKE OR FIRE.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE RUDDER AUTH ON APCH WAS LIMITED TO ONE AND ONE HALF DEGS; MUCH LESS THAN NORMAL. THE RPTR ALLEGED THE LIMITED RUDDER AUTH COMPROMISED THE FLT CREW'S ABILITY TO ALIGN THE ACFT WITH THE RWY DURING THE CROSSWIND APCH; LEADING TO THE SINGLE ENGINE GAR. THE RPTR STATED HE IS IN CONTACT WITH HIS ACR MAINT PERSONNEL TO ATTEMPT TO DETERMINE THE CAUSE OF THE LIMITED RUDDER AUTH. THE RPTR STATED RUDDER AUTH IS LIMITED AT CRUISE SPEEDS; AND THAT LIMITED AUTH WOULD HAVE BEEN IN EFFECT AT THE TIME OF THE ENGINE SHUTDOWN; BUT THE RUDDER AUTH SHOULD HAVE INCREASED AS THE SPEED WAS REDUCED FOR THE APCH; BUT DID NOT DO SO.
