Narrative:
WX conditions: 36 degrees wind 080 to 110 degrees 20-35 KTS. Overnight aircraft covered with wet slush. Scheduled departure time XX20 left. #4 to be de-iced. Completed at XY10 left. First officer inspected wings visually when #1 for takeoff. Runway had been plowed and now covered with 1/2 inch slush (steady rain from XA20 left to XB40 left, then changed to wet snow). Watched an medium large transport and 2 commuters takeoff 1 hour 20 mins before us. PIREP of gusty winds and turbulence by light twin commuter on approach 15 mins prior. Cleared for takeoff, held brakes to 80 percent N1 then began takeoff roll (engine anti-ice on). Called 120 KTS. Shortly after heard series of loud compressor stalls (first officer making takeoff). Speed 110 KTS. Captain immediately initiated abort on runway, no compressor stalls noted during reverse. Slowed to taxi speed on runway with perhaps 1000 ft remaining. Turned off at end and returned to gate. Compressor stalls written up in maintenance logbook and dispatch and maintenance notified. Both engines to be inspected by maintenance. Flight cancelled. Brake temperatures and speeds checked -- normal. No injuries or damage. Suspect water ingestion into engines from runway slush. Crew performance was excellent and immediate, except that in the transition of captain not flying to captain assuming aircraft control with maximum xwinds and slippery runway and short runways, captain initiated full braking and reverse thrust and due to nearly maximum control inputs and strong desire to start stopping, captain overlooked spoiler deployment (manual capability only on takeoffs). Company training emphasizes spoiler deployment during rejected takeoff, but I was so busy I overlooked it. My total concentration was on braking and reverse. First officer said later he saw me forget the spoilers but couldn't reach over my right arm and hands to get to them himself. I erred on procedure and feel damned guilty about forgetting an abort item, but am, at the same time, proud that we did everything else 'first class' and avoided a disaster during extremely harsh conditions. Experience is, however, a great teacher, and makes one very humble. Spoiler deployment will never again be overlooked.

Title: MLG FLC HAS SERIES OF COMPRESSOR STALLS ON TKOF ROLL. TKOF ABORTED.
Narrative: WX CONDITIONS: 36 DEGS WIND 080 TO 110 DEGS 20-35 KTS. OVERNIGHT ACFT COVERED WITH WET SLUSH. SCHEDULED DEP TIME XX20 L. #4 TO BE DE-ICED. COMPLETED AT XY10 L. FO INSPECTED WINGS VISUALLY WHEN #1 FOR TKOF. RWY HAD BEEN PLOWED AND NOW COVERED WITH 1/2 INCH SLUSH (STEADY RAIN FROM XA20 L TO XB40 L, THEN CHANGED TO WET SNOW). WATCHED AN MLG AND 2 COMMUTERS TKOF 1 HR 20 MINS BEFORE US. PIREP OF GUSTY WINDS AND TURB BY LIGHT TWIN COMMUTER ON APCH 15 MINS PRIOR. CLRED FOR TKOF, HELD BRAKES TO 80 PERCENT N1 THEN BEGAN TKOF ROLL (ENG ANTI-ICE ON). CALLED 120 KTS. SHORTLY AFTER HEARD SERIES OF LOUD COMPRESSOR STALLS (FO MAKING TKOF). SPD 110 KTS. CAPT IMMEDIATELY INITIATED ABORT ON RWY, NO COMPRESSOR STALLS NOTED DURING REVERSE. SLOWED TO TAXI SPD ON RWY WITH PERHAPS 1000 FT REMAINING. TURNED OFF AT END AND RETURNED TO GATE. COMPRESSOR STALLS WRITTEN UP IN MAINT LOGBOOK AND DISPATCH AND MAINT NOTIFIED. BOTH ENGS TO BE INSPECTED BY MAINT. FLT CANCELLED. BRAKE TEMPS AND SPDS CHKED -- NORMAL. NO INJURIES OR DAMAGE. SUSPECT WATER INGESTION INTO ENGS FROM RWY SLUSH. CREW PERFORMANCE WAS EXCELLENT AND IMMEDIATE, EXCEPT THAT IN THE TRANSITION OF CAPT NOT FLYING TO CAPT ASSUMING ACFT CTL WITH MAX XWINDS AND SLIPPERY RWY AND SHORT RWYS, CAPT INITIATED FULL BRAKING AND REVERSE THRUST AND DUE TO NEARLY MAX CTL INPUTS AND STRONG DESIRE TO START STOPPING, CAPT OVERLOOKED SPOILER DEPLOYMENT (MANUAL CAPABILITY ONLY ON TKOFS). COMPANY TRAINING EMPHASIZES SPOILER DEPLOYMENT DURING REJECTED TKOF, BUT I WAS SO BUSY I OVERLOOKED IT. MY TOTAL CONCENTRATION WAS ON BRAKING AND REVERSE. FO SAID LATER HE SAW ME FORGET THE SPOILERS BUT COULDN'T REACH OVER MY R ARM AND HANDS TO GET TO THEM HIMSELF. I ERRED ON PROC AND FEEL DAMNED GUILTY ABOUT FORGETTING AN ABORT ITEM, BUT AM, AT THE SAME TIME, PROUD THAT WE DID EVERYTHING ELSE 'FIRST CLASS' AND AVOIDED A DISASTER DURING EXTREMELY HARSH CONDITIONS. EXPERIENCE IS, HOWEVER, A GREAT TEACHER, AND MAKES ONE VERY HUMBLE. SPOILER DEPLOYMENT WILL NEVER AGAIN BE OVERLOOKED.
