Air carrier flight crew reported a rejected takeoff after an engine ingested ice that had come loose from the fuselage due to improper deicing procedures.
I; along with my flight crew arrived at our aircraft [in] the morning. The aircraft had snow and ice on it because there had been a snowstorm that night.We ran through our preflight; the appropriate checklists; started the engines and taxied to a deicing contractor asked us what service we wanted and I told them to deice the entire aircraft; both the body and the wings. (The clean aircraft concept). At some point; we could not communicate with deicing contractor because their radio stopped working. As a result; we had to communicate with deicing contractor through the FBO; the owners of the deicing contractor.At some point; we were informed that the aircraft deicing was complete and that the aircraft was free and clear of ice and snow.At this point; the first officer wrote down the deicing information that was relayed to him. He and I then inspected the leading edges of our wings as instructed in the deicing manual from the cockpit windows. The leading edges looked free and clear of ice on both sides of the aircraft.We ran through the appropriate checklists again; started our engines and taxied to runway XX. We advanced the throttles to max thrust (Contaminated runway; Ice). At 125 knots; we heard multiple compressor stalls; I immediately rejected the takeoff.The Tower told us they heard loud noises (compressor stalls) and that they saw ice leave the fuselage and get ingested engine #1.We taxied back to the company ramp and shut down our engines. Our mechanic; who was on the flight then got off the airplane; reentered the aircraft and said to us; 'You guys are not going to believe what you see on the wings'. We then got off the aircraft and saw that ice was still on the aircraft.We did not see this ice on the aircraft when we conducted our visual inspection. Our flight engineer is thinking that this ice possibly left the fuselage and was deposited on the wings. Identification: After rejecting the takeoff and taxiing to the ramp.[The cause of the incident] was: deicers did not deice the aircraft thoroughly or correctly.[The pilot flying] immediately rejected the takeoff.Suggestions: The deicers need to do their job and deice the aircraft correctly.
I arrived at aircraft to begin my prefight. I immediately noticed that plane was covered in snow and ice and would need to be deiced. After completing our preflight procedures. The captain made his briefing and he was to be the pilot flying. During the briefing the crew discussed moving the airplane to deicing contractor to be deiced. We ran the appropriate checklists and moved the airplane to the east ramp. We established communications with the deicers and they began deicing us with type I fluid. While we were being deiced I worked on the weight and balance and calculated the performance data. The FBO reported that they were done with the deicing and that the plane was clear of snow and ice. The captain and the first officer viewed from their windows and confirmed that there was no visible ice or snow from their vantage points (Ref; Deicing/Anti Icing Manual) We then began with the appropriate checklists to proceed with our trip. Once on the runway after being cleared for takeoff with tower. We advanced the throttles to our max power EPR settings and the aircraft began to accelerate. I immediately heard a thud followed by a few more. The captain then aborted the takeoff and communicated our issue with the tower. The tower commented that they observed a large amount of snow and ice flying off the top of the fuselage and being ingested in the #1 engine. After running the checklists we shut down the airplane. I departed the airplane to do my post flight inspection and noticed the snow and ice on the plane. My initial thought was this must be the snow and ice that came off the top of the fuselage that the tower had stated. We then reported to operations.
