Narrative: Departed gate dual engine power out onto taxiway. Captain was Pilot Flying. Took off [Runway] XXL heading 220 to 5;000 [feet]. It was a normal ALT-TO1 take off. Prepare for level off at 5;000; reduce power for a 24;000 1000 fpm climb. Prior to 5;000 cleared to 15;000 apply climb power. Stable climb at 24;000. At approximately 5;000 [feet] there was a loud bang and the aircraft shook; moments later the ENG 1 OUT EICAS message is presented. Captain ensured AC control; while the First Officer [advised with ATC] and asked for level off at 8;000 [feet]. Cleared as requested. Captain set a 500 fpm climb and turned on the auto pilot and the First Officer began the engine failure checklist. During the checklist; the Flight Attendant called us to inquire about the bang; told him about the failure and our imminent return to ZZZ and that we would call him back shortly. Completed the engine failure checklist. Engine restart was discussed but we decided not to attempt it because of the bang; there was likely damage. After completion of the engine failure checklist the First Officer began the single engine landing checklist. During this time we leveled off at 8;000 [feet] and received some vectors from ZZZ Departure. While the First Officer prepared the landing data The Captain called the Flight Attendant back and made an announcement to the passengers. Departure reached out shortly after that and the Captain requested an approach to [Runway] XXC and CFR (Crash Fire Rescue equipment) standing by. Transferred to approach continued vectors on course Captain and First Officer quickly reviewed the approach setup and confirmed below landing weight. ACARS message sent to dispatch to inform them of the engine failure and return to ZZZ. Around 500 ft AGL the auto pilot was drifting left of course. Turned the auto pilot off corrected and made a normal touchdown on [Runway] XXC. Exited the runway [and] directed to taxi beyond intersection and CFR was on a separate ground freq. parking break set; after landing complete. CFR confirmed there were no indications of a fire; they followed us to the alley. We parked and deplaned normally. No injuries were reported and no one requested medical attention.


Second narrative: We departed gate with both engines running onto taxiway. Captain was the pilot flying. We executed a normal ALT-TO-1 takeoff from 10L turning to heading 220 and climbing to 5;000 feet. After Takeoff Checklist was complete and we were established in climb power. Captain prepared for level off at 5;000 feet by reducing power for a 240kt 1;000 fpm climb. Prior to 5;000 feet we were cleared to 15;000 feet and additional power was applied reestablishing a stable climb to our new clearance altitude.While climbing through approximately 5;000 feet a loud bang occurred and the aircraft shook. Moments later the ENG 1 OUT EICAS message was presented. Captain ensured aircraft control and we determined that we would climb to 8;000 feet to ensure we would be above weather build-ups in the immediate area while we continued to work through the emergency. I [advised] ATC and asked for level off at 8;000 feet which we were cleared for. Captain set a 500 fpm climb and turned on the autopilot and I began the Engine Failure Checklist. During the checklist the Flight Attendant called us to inquire about the bang. He was told about the failure; our imminent return to ZZZ; and that we would call him back shortly. During completion of the Engine Failure Checklist; a potential restart of engine 1 was discussed. Fuel; Oil; and N1 Rotation were present; however; it was determined that due to the loud bang that occurred; it was likely that substantial damage may have occurred to engine 1 and as such; a potential restart attempt would not be prudent. The Engine Failure Checklist was completed. During this time we leveled off at 8;000 feet and received additional vectors from ZZZ departure. After completing the Engine Failure Checklist; I began the Single Engine Landing Checklist. While I prepared the landing data; Captain called the Flight Attendant back and made an announcement to the passengers. Departure reached out shortly after that and Captain requested an approach to [Runway] XXC and to have Crash Fire Rescue (CFR) standing by. We transferred to approach control and continued vectors to the ILS [Runway] XXC localizer. It was confirmed that both the Engine Failure Checklist and Single Engine Landing Checklist were complete. Captain and I reviewed the approach setup and confirmed the aircraft was below landing weight. I sent an ACARS message to dispatch to inform them of the engine failure and subsequent return to ZZZ and requested a gate be assigned. We continued with the approach. Around 500 ft AGLl the autopilot began drifting left of course. Captain turned the autopilot off; corrected; and made a normal touchdown on [Runway] XXC. We exited [Runway] XXC at exit and were directed to taxi past the intersection and stop on taxiway where CFR was standing by on a separate ground frequency. The parking brake was set and after landing checklist completed. CFR confirmed there were no indications of a fire. Taxi was initiated to gate and CFR followed us to the alley as a precaution. We parked and deplaned normally. No injuries were reported and no one requested medical attention.
