They also state that there was no evident pre-impact internal failures.
There quite possibly could have been some external component that has failed resulting in a loss of power (ie fcu). (note, I am not stating any kind of hypothesis here, just trying to highlight what the terminology in the prelim report is saying).
Like I said previously, the prelim report won't answer all the questions and we have to wait for a more thorough report after further investigation. All this has done is stated some known facts- not necessarily anything about the causal factors..
Spinex, you said it mate, more questions than answers.
fairly sure Ng will go to zero if engine is shut down. Np will do whatever the prop is doing.
FCU drive shear should go to full noise. Well on a - 20 and -34, maybe -41 and -42 have different arrangement. In my uneducated opinion
