LZ,
thank you for the ethos behind FMECA, I found it most interesting. You appear to have actual hands on experience of the detail of such an analysis on the EH101.
I was surprised that you were so specific in pointing out who, in your opinion was allegedly responsible for removing identified catastrophic events from a FMEA. Were I one of the persons concerned (I am not) I would be keen to question your statement. Nevertheless, your concern for the operators is clear and worthy. Do the operators have access to the Merlin FMEA through their procurement or airworthiness chain? Even if a company put together a weak safety case would it not be checked as part of the airworthiness requirement? Also , was the rotor brake problem that you refer to in your previous post the one that caused the recent EH101 crash? Because if so, surely that would have focussed the airworthiness chains attention on the safety case?
Thanks again
