Aircraft; Procedure
During a maintenance evaluation flight of Aircraft X; the right engine flamed out during a go around. A restart was attempted and unsuccessful; landed roughly 20 minutes later on Runway XX. I was the Pilot Flying for the evaluation flight. We departed ZZZ; flew the planned route up to FL360. The test flight was conducted to examine the right engine which had been 'slow to spool'. Departure; enroute; descent; and approach phases all appeared normal. The evaluation flight requested two CATIII approaches to go arounds and one full CATIII autoland. During the first go around; we climbed out; cleaned up the aircraft and were given vectors back for another approach to Runway XX. As we were leveling off at 4;000 feet; we began a 90 degree turn; at this point the L and R Utility Busses came offline and the right engine flamed out. I remained in control of the aircraft; and also operated the radios. The Captain ran the QRH and was unsuccessful at a relight. We agreed on a course of action to return to ZZZ; we ran the appropriate checklist and joined the approach for Runway XX; landed without issue.
Released flight ZZZ-ZZZ test flight for Aircraft X a slow to spool right engine; and following was to be performed by the crew.Flight profile/request/mission for evaluating specific system/problem: - Normal takeoff and climb as flight planned and ATC to FL 350 or above for an hour. Monitor engine parameters.- Crews should be aware of proper system functions and note discrepancies.- Normal CAT 3B approach to ZZZ; shooting missed approach. Perform 2nd. CAT 3B approach to ZZZ; shooting missed approach. If no engine issues flight to continue to ZZZ for full Cat 3B approach and landing.- Notify Maintenance and Flight Control via aircraft radio of any problems or write-ups for review. Crews should be aware of proper system functions and note discrepancies.I noticed the last missed approach on FUSION and then after landing; Captain called [and] asked me about an [event] and I said I was not aware of one; he said Aircraft X he believed had one. I then asked Maintenance and [operations] and was advised that yes flight had [advised ATC of an event] due to a right engine failure. No further information at this time but the flight has landed on/in times ZZZ safely. Flight did [advised ATC] and CFR rolled; no other information was given to me by the crew or anyone else.
B767 Pilot and dispatcher reported during a maintenance check flight; the right engine flamed out on final.
