Narrative:

After normal preflight of md-80 and a maintenance layover check as well as a security sweep; our aircraft was loaded with passengers and cargo. The aircraft had been sitting at the hangar during the snow storm over the weekend. The aircraft appeared clear of ice and snow during the drag-up; from the cabin overlooking the wings; and during the walkaround in bright sunlight with gusty winds. Taxi and engine starts were normal. During takeoff roll; between 60-75 KIAS; the aircraft appeared to accelerate normally; but both pilots felt what appeared to be a compressor stall in either or both engines. The takeoff was aborted at low speed and the runway was cleared. An after landing check was performed and a notification call to tower was made. After conferring with the aft flight attendants; a decision was made to have the aircraft towed to a gate and the right engine was shut down as we coordinated for a tug. All engine instruments indicated normally throughout the rejected takeoff as well as after the fact. The aircraft was then connected to a tug and the left engine was then shut down. A FOD truck was dispatched to the runway; but only found 'slush' -- no metallic debris. An aircraft behind us said that he had seen debris coming out of the engine on power-up. Another voice on tower frequency also said that another md-80 had the same thing happen and had bent compressor blades earlier in the day. We were towed to a new gate and maintenance met the aircraft. A visual inspection indicated that there was damage to the #2 engine; but nothing appeared abnormal with #1. Maintenance also reported that there was some snow/ice still on the wing roots of the aircraft even though the rest of the aircraft appeared clear. We suspected that some ice FOD had remained in the inlets of the engines and came loose during throttle-up creating the compressor stalls. (The md-80 has some history of this occurrence.) my recommendations to prevent these problems in the future would be: 1) plug or cover engine inlets during times of freezing precipitation to prevent water from entering the engine inlets and freezing -- turning into a potential FOD hazard. 2) have maintenance inspect engine inlets if an aircraft has been sitting in freezing precipitation prior to re-entry into service -- especially if the aircraft has a known history of this type of problem. A visual inspection with some type of lift device would be required as the inlets are too high to inspect from the ground during a walkaround. 3) also; pilots need to be particularly vigilant during times like this. Some ice/snow could still remain on an aircraft in hard-to-see locations even though the rest of the aircraft appears 'clean.' (unusual since normally snow or ice would be all over the aircraft prompting the crew to deice before departure.)
