EMER DECLARED AFTER ACFT MLG EXPERIENCES A SERIES OF VIOLENT COMPRESSOR STALLS ON GAR PROC.

Narrative

THE FLT FROM CHARLOTTE TO NEW YORK WAS MOST ROUTINE UNTIL NEARLY CONCLUDING THE LDA-A FINAL APCH COURSE -- LGA. AT A POINT APPROX 3 MI FROM THE RWY THRESHOLD WE WERE INSTRUCTED TO 'GAR' AS A RESULT OF INADEQUATE WAKE TURB SEPARATION FROM THE DEP OF A HVY JET ON INTERSECTING RWY 31. AS THE PWR LEVERS ADVANCED TO THE APPROPRIATE TOGA SETTINGS THE R ENG REACTED WITH A SERIES OF VIOLENT COMPRESSOR STALLS. AS NORMAL FLT OPS WERE SIGNIFICANTLY IMPACTED (BY INTENSE CTLABILITY BUCKING AND BUFFETING); I ELECTED TO IMMEDIATELY DECLARE AN EMER AND SPECIFICALLY REQUESTED STAND BY EMER EQUIP. THERE WAS SIGNIFICANT AIRBORNE TFC AROUND US. WE CLBED SLIGHTLY ABOVE GAR ALT WITH A TCASII ALERT. TFC WAS VISUALLY SIGHTED. AS DIAGNOSTIC PROCS WERE INSTITUTED WE STABILIZED THE ENG TO WITHIN NORMAL OPERATING PARAMETERS -- RESULTANT THRUST WAS MORE THAN ADEQUATE FOR A NORMAL 2 ENG LNDG (EVEN CONSIDERING ANOTHER POSSIBLE GAR) AND THUS NEGATING AN INFLT ENG SHUTDOWN. PAX WERE NOTIFIED OF SIT; LNDG WAS NORMAL; ENG WAS SHUT DOWN WHILE PROCEEDING TO GATE.
