Narrative:

Flight xyz was cleared to climb to 17000 ft while outbound on the hugo 5 robax departure from clt. After climbing out of the tops at 14000 ft MSL the left engine failed and the climb rate stopped with loss of airspeed while crew secured engine. We notified ATC of engine failure after 15 seconds and then told them we needed lower. We squawked 7700, landed in clt. I was told we lost separation on another aircraft. 4.6 SM at 600 ft we did get a TA but not a TCASII RA. Callback conversation with reporter revealed the following information: the reporter stated the engine was torn down by maintenance and inspection revealed the bull gear in the pwrplant gear box failed. The reporter said the loss of separation was reported to them by ATC but they never had a visual sighting but did have a TA warning on TCASII.
