All newly designed helicopters (regardless of which way round the rotors go) have teething problems, some of which are quite serious. This is pretty much accepted by the industry and by many of our clients (one of which very sensibly requires at least 1000hrs on a new fleet before trusting it to their passengers).
But should it be like that? What is the point in having the certification process when so much slips through it. All it seems to do is prolong the development process, cost a fortune and lull us into a false sense of security. It is clearly not a robust process.
What it most certainly does is to make fixing problems take much longer. Your fancy electronic box has a software bug? Certainly Sir, we can fix that but it will take 3 months to redesign and then another 6 months to get it through certification ( at the end of which there will still be those bugs that we have not yet found!) and in the mean time you'd better get used to the bug!
Perhaps certification should be an internal manufacturer process but have strict rules that when an item is found to be non-compliant, buggy or self-destructive the technical management are publically castrated. That would make them pay attention though I suspect there would still be a lot of squeaky managers!
