last year we had a similar thread on a discussion forum here in europe.

fact is:
i have seen all brands of turbine fail:
endless calls with amt, cause of malfunction, flameout of simjet, behotecs or lost blades of JC. most of them have the same supplier of turbine wheels, bearings a.s.o., combustion chamber design of the same origin, this explains why it is an illusion that there will be a turbine manufacturer with a "perfect" turbine on the market in the near future.

anybody who believes in that, is a dreamer.
cant hear "my turbine worked flawless" anymore.

in two and a half year of turbíne flying my personal list of turbine damage is:
2 shot ECU (my own fault)
1 suspect fuel pump
1 turbine wheel (own fault due to overrev)
1 broken compressor wheel (dirteater )
1 worn NGV
1 turbine wheel (one lost blade)
1 destroyed bearing (own fault due to a selfmade handheld electric starter)
1 heat worn turbine case
(however you have to consider that our turbines always work and are setup at their limits, revs as well as temp).
