Synopsis
CE-680 flight crew reported engine failure during departure climb. Returned to departure airport and landed uneventfully.
Narrative
After departing Runway XX at ZZZ on the ZZZZZ SID and climbing through approximately 5000 feet. We had a very loud bang and vibration in the left engine. The left engine overtemped above 950 degrees. The engine appeared to fluctuate in temp and N1 and N2. I retarded the left throttle to assess the controllability of the engine. After a period of time the N2 appeared stabilize at 60%. But we still had a good vibration coming from the left engine. We did not have any secondary indications of the issue. We also did not have any CAS messages. Due to the continued vibration and over temping of the engine we discussed shutting down the engine as we were not sure the nature of the damage that had happened to the engine. We proceeded with the inflight engine shutdown QRC. We [requested priority handling] and received vectors for time to complete other checklists and programming to prepare to return to ZZZ and land on Runway XX. At the time the winds best favored Runway XX. After landing we remained on the Runway for CFR to assess or exterior situation. Once given the all clear we were towed to a maintenance ramp.
Second reporter narrative
We departed Runway XX on the ZZZZZ [SID]. The takeoff and initial climb was normal until reaching approximately 5000 feet when the left engine began to fail. There were several loud bangs followed by heavy vibration which we believed was a compressor stall. There were no associated CAS messages. The left engine rolled back. The captain and Pilot Flying (FP) noted an engine over-temperature. At one point; I believe I saw N1 as low as 30%. We then [requested priority handling] and received delay vectors.We elected to shut down the left engine by running the INFLIGHT ENGINE SHUTDOWN QRC and prepared the aircraft for landing on Runway XX due to winds through the use of the ENGINE INOP APPROACH and ENGINE INOP LANDING checklists. The landing and rollout were normal. We rolled to the end of Runway XX where we were met by CFR.
