How to or How NOT to?

What are you talking about?

C'mon guys, EVERY engine has teething problems.

GE90 was having issues upon its EIS
The RB211 ruined Rolls(ya not a good example)
The JT-9D by P&W on the 747 test fleet was surging due to ovalization of the compressor frame
...just to name a few from memory

Rolls has built dozens of commercial straightpipes and fans over the last half century and has successfully logged millions of flight hours.
 
I must say though it was a creative burn, and I did leave the door wide open(that's what she said).

Just curious though, how many un-contained failures have there been from other manufactures? I remember the DC-10 that crashed landed because an engine had an un-contained failure. Weren't those GE engines?

Yep, the UAL 232 was an uncontained failure of a CF-6. I went to a GE class a couple of months ago and there has been only one other uncontained failure of a GE commercial engine. Well....this is what we were told (not sure if this is fact or not). The UAL failure was blamed on both UAL for not finding a crack during rebuild and GE for having a metallurgical flaw during manufacture.
 
I take it back. The GE rep was full of crap. A simple search has revealed that the CF6 has had a history of HPT failures. Did you see in the report on N330AA that parts of blade 1 from the HPT was found 2600 feet away? Damn!

Yeah, that's insane. I think that the high-pressure rotor on those engines can rotate up to somewhere around 11,000 RPM.
