I have every confidence in the AAIB and the CAA regarding accident investigating, very professional lot. My question is why did Eurocopter not let all operators and maintainers know when the first incident occured. It was an airworthiness issue and we should all have been warned as soon as possible, granted there probably wasn't much anyone could have done but forewarned is forearmed. As an engineer I realise how much trust I put in the manufacturer that they have got it right and how much trust pilots put in engineers that we have got it right. It is worrying when a manufacturer withholds vital information from us all.
