Narrative:
This report is about aircraft X specifically. In january; I dumped 80;000 pounds of fuel and returned to ZZZ1 due to a hydraulic status message that had generated the following eg note prior to our flight: 'boeing is concerned about a recent failure (flash fire) of the right-hand acmp on this aircraft.' I was assured that everything was fixed and that the aircraft had been flying around for almost a month with no complaints. 30 minutes into our flight (status messages are inhibited for 30 minutes after liftoff) we got the status message and then returned to ZZZ. Last night I decided to look at the maintenance history of aircraft X to see -- what was the original cause of the problem? Instead of finding problem; I saw that the aircraft has had the same problem ever since my return to the field. The same problem was deferred in ZZZ2 due to time constraints. This is a fire hazard and the operation of this aircraft should be stopped immediately until the real problem is found. I called the flight manager last night to report this.
