An earlier rumor of a catastrophic failure of a Rolls-Royce Trent 800
engine during an Emirates' B777 take-off was confirmed by this week's
Flight International (9/24-9/30). Both R-R and Emirates have been very
quiet about this incidence. Earlier report indicated the compressor
failure was due to a foreign object damage (possibly a birdstrike).
However, Flight International alleged metal-chip detection from the
front bearing cage. (Does Cathay's grounding of the Trent 700-powered
A330 ring a bell?)
In the same issue of the magazine, R-R ran an ad boasting Trent 800's
consumption of less than one quart of engine oil (for lubrication) on
the B777 record-setting round-the-world flight. I was told by a very
reliable source that the engine from one of R-R's American competitors
"consumes" engine oil at least ten times more than the other two B777
powerplants. However, the Trent 800 seems to have experienced many
more woes than either the PW4000 or GE90. (Were I a Delta executive, I
certainly would seriously reconsider the B777 engine selection before
excercising Delta's B777 options.)
