I don't know for a fact that it was catastrophic.  I was merely repeating
what I had heard from two different sources that it was a catastrophic
failure.  For the second time, Flight International reported the
incidence as catastrophic and cited the failure was due to a high
compressor blade fatigue.  If you have evidence that the FI report was
inaccurate, perhaps you should say so to FI.

> By the way, who says Cathay hate twins?

Hate may be a strong word, but I'm seriously doubt they are very
pleased with either the A330 or the B777.  Don't tell me that after
four well-publicized inflight shutdowns in five months, three-week
grounding and other lesser-known incidences that Cathay still love the
A330.  Cathay has been very conservative.  For nearly 15 years,
(between 1980 and early 1990's), Cathay had introduced only one new
aircraft type (a major new derivative, the B747-400; there was the
B747-300, but it's practically the same as the B747-200).  Recently, in
a period of two years, Cathay had introduced three new aircraft types
(the A330, A340, and B777).  IMHO, Cathay's "inexperience" in
introducing new fleet as well as too many new types in a very short
period of time further compounded teething problems that were expected
for new aircraft types.  The problematic Trent 700 certainly made it
worse.  Cathay was one of the few which were very pleased with the A330
initially.  However, I don't think they are as pleased as they used to
be.  Cathay must be very thankful that it has only one A330 route (to
Colombo, Sri Lanka) that rely on the ETOPS certification of the A330.
If Cathay had more ETOPS routes, the suspension of Trent 700-powered
A330 ETOPS rating would be a disaster for its operation.  Of course,
Cathay has no plans to abandon twins, because the airline has made too
much investment in them.  It does not mean that CX likes the planes.
It has just been announced that China Southwestern is going to take
three A340s for domestic operations (see another post).  Singapore
Airlines also uses the A340 on quite a number of short-haul flights.
Thus, I won't be surprised if Cathay will rely more on the A340 in the
future.  Airlines in that region are known to "misuse" planes.
Currently, CX does use the A340 on regional routes, but these flights
are mostly "fill-ins" between long-haul flights to Europe and North
America.
