Situational Awareness
Aircraft Equipment Problem Critical
Aircraft Aircraft Damaged; Flight Crew Rejected Takeoff
Aircraft
Both engines started during pushback. Taxi to runway; approximately number 7 in line for takeoff; so 10-15 minute taxi/warmup. Cleared onto runway and cleared for takeoff during turn on to runway. Captain transferred control of aircraft; including throttles to me as we completed the turn. Aligned with the centerline; I advanced the throttles to approximately 1.4 EPR; noted all parameters normal; and called for autothrottle ON. As the autothrottle advanced; a loud bang and immediate yaw to the left was felt. I applied right rudder pedal to keep the aircraft on centerline as the Captain simultaneously retarded the throttles. By the time I looked down to the engine instruments; both engines were still running and showed just over 1.05 EPR. Our speed was always lower than 60 knots; and as we rolled out; we informed the Tower and were instructed to exit the runway. As we exited the runway; I spoke to the FA's and confirmed that there were no additional indications of any problem other than the engine failure and that all passengers were calm and safe. Upon exiting the runway; we were informed by ATC that there were reports of FOD on the runway. We stopped the aircraft; briefly discussed the problem; and agreed that the left engine was the one with the problem. We shut down that engine and felt a bit of an abnormal vibration as it shut down. We then started the APU and eventually taxied back to our assigned gate. Unsure how it could have been prevented. All procedures were followed and a safe outcome was achieved.
Taxied into position for takeoff. After cleared for takeoff; First Officer assumed control of aircraft and pushed throttle up to 1.4 EPR. All engine parameters normal. He then called for autothrottles ON and pushed up throttles while releasing brakes. Right as power reached MAX setting; felt and heard a thunk with a yaw to the left corrected by First Officer. I assumed control and aborted takeoff at around 20 knots retarding the throttles. We informed Tower we were aborting takeoff and requested taxi to next intersection to clear. As we stopped; a flight attendant called to inform us of a loud bang and heavy vibration. We shut down the left engine. I noted higher EGT on left side and that the ART had fired. Tower then notified us that we had FODed out the runway. We started APU; called Operations and taxied uneventfully to a new gate. Maintenance came up after deplaning and said that we had lost aft turbine section of left engine.
MD83 flight crew experiences a left engine failure just as the power is pushed up for takeoff and rejects.
