AN ACR MD80 FLT WAS ABORTED DUE TO NOISE; EPR FLUCTUATION; AND YAW; DURING TKOF ROLL. POSTFLT INSPECTION REVEALED BENT FAN BLADES ON THE R ENG; AND ICE ON THE WINGS AND LEADING EDGES OF THE FLAPS. THE CAPT BELIEVES THAT THE ACFT WAS NOT PROPERLY DEICED.

Narrative

BEFORE THE FLT FROM YYC TO ORD THE GND SVC CREW TOWED ACFT TO THE GATE FROM ITS OVERNIGHT PAD. THE ACFT HAD ICE ON THE WINGS SO WE INFORMED THE CREW WE WOULD NEED TO BE DEICED. THE WX WAS CLR WITH A TEMP OF 3 DEGS C. WE STARTED THE ENGS AT THE GATE AND APPLIED ENG ANTI-ICE. WE THEN PREPARED THE ACFT FOR DEICING WHICH APPEARED TO TAKE PLACE NORMALLY. AFTER DEICING WE TAXIED TO RWY 34 WITH NO DELAYS AND WERE CLRED FOR AN IMMEDIATE TKOF. IT WAS MY TKOF AND WE WERE MAKING A MAX PWR TKOF. I ADVANCED PWR TO 1.4 EPR AND CALLED AUTOTHROTTLES; WHICH THE CAPT ACTIVATED. ACCELERATION WAS NORMAL UNTIL ABOUT 80 KTS WHEN I NOTICED A MUFFLED NOISE AND THE ACFT YAWED SLIGHTLY R. I GLANCED ONCE MORE AT THE AIRSPD AND SAW 90 KTS AND THEN FOCUSED MY ATTN BACK OUTSIDE. THE ACFT YAWED R ONCE MORE AND THE CAPT INITIATED THE ABORT BTWN 90-100 KTS. WE RETURNED TO THE GATE AND LEFT THE FLAPS EXTENDED SO AN INSPECTION COULD BE MADE TO INSURE THERE WAS NO DAMAGE TO THE FLAPS. UPON INSPECTION OF THE R ENG; A NUMBER OF FAN BLADES WERE BENT OUT OF SHAPE. CONTRACT MAINT INFORMED US THAT THE FAN WOULD HAVE TO BE CHANGED IF NOT THE WHOLE ENG. UPON INSPECTING THE WINGS NO DAMAGE WAS FOUND; BUT THERE WAS ICE ON THE WINGS JUST AFT OF THE HEATER BLANKETS AND ON THE LEADING EDGES OF THE FLAPS. SUPPLEMENTAL INFO FROM ACN 324727: ACFT COMMENCED TKOF ROLL ON RWY 34 USING MAX PWR DUE TO HAVING BEEN DEICED AT GATE. AT APPROX 80-90 KTS I NOTICED THE R EPR FLUCTUATE AND FELT ACFT PULL SLIGHTLY TO R. I INITIATED AN ABORT WITHOUT INCIDENT AND CLRED RWY. AFTER ARR AT GATE I AND THE FO ALONG WITH MAINT; OBSERVED SEVERAL BENT BLADES ON THE FOREMOST COMPRESSOR BLADE. WE ALSO OBSERVED SEVERAL SMALL SPOTS OF ICE ON THE AFT PART OF THE R WING. IT IS UNLIKELY THIS WAS PICKED UP DURING TAXI OR EVEN DURING THE ABORT AS THE WX CONDITIONS WERE CLR AND THE RWY WAS ALSO BASICALLY FREE OF CONTAMINANTS. THIS LEADS ME TO BELIEVE THAT THE ACFT WAS NOT PROPERLY DEICED TO BEGIN WITH.
