Engine failures seem to be the hot topic these days. I found this one that's pretty interesting. Great read with some good pics of the damaged components accompany the article.
"The Australian Transportation Safety Board (ATSB) have released their final report concluding the probable cause was:
- The number-2 engine failed as a result of severe localised overheating and burn-through of the stage-1 nozzle guide vanes, and the subsequent destruction of the downstream turbine components.
- Damage to the stage-1 nozzle guide vanes was probably related to pre-existing and undetected defective fuel injector nozzle/s.
Other safety factors
- During the immediate response to the engine failure, the flight crew were unable to activate the number-2 engine fire suppression system.
- The engine condition trend monitoring program did not provide forewarning of the turbine system damage that eventually led to the engine failure, most likely as a result of the localised nature of the developing damage."From:
