See Safety Analysis on p.8 of the report...
During the previous flight, the engine manufacturer’s condition monitoring program had noted some adverse trends in the engine’s operating parameters, prompting the issue of an Urgent Remote Diagnostic Notice that alerted the operator to the potential deterioration of the aircraft’s No 3 engine high pressure compressor (HPC) efficiency. As a result, an inspection of the engine was scheduled upon the aircraft’s return to the main base in Dubai. At the time of the failure event, the engine’s exhaust gas temperature (EGT) and HPC trend monitoring criteria were not yet at a level that would have required an immediate inspection of the engine.
I can't understand why the aircraft was cleared to do another sector AFTER an Urgent Remote Diagnostic Notice was issued as a result of adverse trends in the engine operating parameters.
