Narrative:

On a through flight crew change, I picked up the aircraft. On my walk around I noticed some ice on nose gear splash guard and cleaned it off. Maintenance performed a walk around as I did mine. The maintenance man found a small amount of ice on a flap and he cleaned it off. No other ice was found. Taxi out was uneventful on takeoff. As we passed about 100 KTS, we heard a bang and the aircraft yawed. The captain aborted the takeoff and we cleared the runway and stopped. We had the aircraft inspected and slush/ice was found falling out of the wheel well areas. The runway was inspected for foreign object damage and none was found, and both engines were running normally at idle. No aircraft damage was found and we taxied to the gate. After shutdown, slush was found falling from the wheel well areas. The aircraft had come from pdx where it was very snowy and slushy. As this was a crew change, we were not aware of the conditions at pdx and the possibility of previous engine damage from the takeoff from pdx. Perhaps we should have a logbook entry and an expanded postflt procedures for aircraft coming out of snowy/slushy airports. We are trained to have a clean aircraft. However, when the WX is clear and the wings/fuselage area is clean, we may not think about the previous stops. Also, the hidden areas of the wheel wells are not a part of our normal walk around, and we are not required to open the gear doors for inspection. Callback conversation with reporter revealed the following information: this crew flies the md-82 for a second level united states air carrier. They had never flown together before and had never even met each other before. They agree that this had nothing to do with the incident as their air carrier is rightfully proud of its crew standardization. The first officer said that this was 'a good cockpit resource management exercise.' he is a strong advocate of cockpit resource management. The incoming crew failed to tell this crew of the ice and slush problem at pdx, so this crew did not think to look especially for it. There is no chance that the ice came from the wings. Captain thinks that the damage was done previously, maybe on approach, and did not show up till their takeoff. The first officer thinks that the ice may have come from the flap area. He inspected the flaps while they were up, and ice may have dropped off on takeoff roll. The sea runway, as the sky, was completely clear. The air carrier gave the crew another aircraft immediately to complete their trip. Supplemental information from acn 296231: while parked at the gate, after our abort, slush was observed falling from upper gear well areas and landing on lower gear hardware. This slush was hidden from view by gear doors that are usually not lowered during preflight. Also, slush was found under the nose gear jack point and this also was hidden from normal view. I suspect foreign object damage was done during the portland departure from a contaminated runway/taxiway or during gear extension at landing in sea.

Title: HIGH SPD ABORT.

Narrative: ON A THROUGH FLC CHANGE, I PICKED UP THE ACFT. ON MY WALK AROUND I NOTICED SOME ICE ON NOSE GEAR SPLASH GUARD AND CLEANED IT OFF. MAINT PERFORMED A WALK AROUND AS I DID MINE. THE MAINT MAN FOUND A SMALL AMOUNT OF ICE ON A FLAP AND HE CLEANED IT OFF. NO OTHER ICE WAS FOUND. TAXI OUT WAS UNEVENTFUL ON TKOF. AS WE PASSED ABOUT 100 KTS, WE HEARD A BANG AND THE ACFT YAWED. THE CAPT ABORTED THE TKOF AND WE CLRED THE RWY AND STOPPED. WE HAD THE ACFT INSPECTED AND SLUSH/ICE WAS FOUND FALLING OUT OF THE WHEEL WELL AREAS. THE RWY WAS INSPECTED FOR FOREIGN OBJECT DAMAGE AND NONE WAS FOUND, AND BOTH ENGS WERE RUNNING NORMALLY AT IDLE. NO ACFT DAMAGE WAS FOUND AND WE TAXIED TO THE GATE. AFTER SHUTDOWN, SLUSH WAS FOUND FALLING FROM THE WHEEL WELL AREAS. THE ACFT HAD COME FROM PDX WHERE IT WAS VERY SNOWY AND SLUSHY. AS THIS WAS A CREW CHANGE, WE WERE NOT AWARE OF THE CONDITIONS AT PDX AND THE POSSIBILITY OF PREVIOUS ENG DAMAGE FROM THE TKOF FROM PDX. PERHAPS WE SHOULD HAVE A LOGBOOK ENTRY AND AN EXPANDED POSTFLT PROCS FOR ACFT COMING OUT OF SNOWY/SLUSHY ARPTS. WE ARE TRAINED TO HAVE A CLEAN ACFT. HOWEVER, WHEN THE WX IS CLR AND THE WINGS/FUSELAGE AREA IS CLEAN, WE MAY NOT THINK ABOUT THE PREVIOUS STOPS. ALSO, THE HIDDEN AREAS OF THE WHEEL WELLS ARE NOT A PART OF OUR NORMAL WALK AROUND, AND WE ARE NOT REQUIRED TO OPEN THE GEAR DOORS FOR INSPECTION. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THIS CREW FLIES THE MD-82 FOR A SECOND LEVEL UNITED STATES ACR. THEY HAD NEVER FLOWN TOGETHER BEFORE AND HAD NEVER EVEN MET EACH OTHER BEFORE. THEY AGREE THAT THIS HAD NOTHING TO DO WITH THE INCIDENT AS THEIR ACR IS RIGHTFULLY PROUD OF ITS CREW STANDARDIZATION. THE FO SAID THAT THIS WAS 'A GOOD COCKPIT RESOURCE MGMNT EXERCISE.' HE IS A STRONG ADVOCATE OF COCKPIT RESOURCE MGMNT. THE INCOMING CREW FAILED TO TELL THIS CREW OF THE ICE AND SLUSH PROB AT PDX, SO THIS CREW DID NOT THINK TO LOOK ESPECIALLY FOR IT. THERE IS NO CHANCE THAT THE ICE CAME FROM THE WINGS. CAPT THINKS THAT THE DAMAGE WAS DONE PREVIOUSLY, MAYBE ON APCH, AND DID NOT SHOW UP TILL THEIR TKOF. THE FO THINKS THAT THE ICE MAY HAVE COME FROM THE FLAP AREA. HE INSPECTED THE FLAPS WHILE THEY WERE UP, AND ICE MAY HAVE DROPPED OFF ON TKOF ROLL. THE SEA RWY, AS THE SKY, WAS COMPLETELY CLR. THE ACR GAVE THE CREW ANOTHER ACFT IMMEDIATELY TO COMPLETE THEIR TRIP. SUPPLEMENTAL INFO FROM ACN 296231: WHILE PARKED AT THE GATE, AFTER OUR ABORT, SLUSH WAS OBSERVED FALLING FROM UPPER GEAR WELL AREAS AND LNDG ON LOWER GEAR HARDWARE. THIS SLUSH WAS HIDDEN FROM VIEW BY GEAR DOORS THAT ARE USUALLY NOT LOWERED DURING PREFLT. ALSO, SLUSH WAS FOUND UNDER THE NOSE GEAR JACK POINT AND THIS ALSO WAS HIDDEN FROM NORMAL VIEW. I SUSPECT FOREIGN OBJECT DAMAGE WAS DONE DURING THE PORTLAND DEP FROM A CONTAMINATED RWY/TXWY OR DURING GEAR EXTENSION AT LNDG IN SEA.
