Gentlemen, don't you think that the 787's problems fade into insignificance when compared to the horrendous uncontained turbine burst of the A380's engine(s)?? Yet that subject seems no longer to be mentioned. How come?
Probably because the mis-bored oil stub pipes have been identified and replaced on all Trent 900s.
RR have also re-programmed the FADEC to shut off fuel to an engine where an IP turbine overspeed is detected.
This incident is now history. The problems on the 787 are ongoing and the jury is still out on the battery 'fix'.
