All very true, but as I have studied composite construction and use for 30 years, I can no longer remain silent as I read this thread.
Composites are safe.
Composites age and we have few methods of assessing them as they do so.
But what a lot of you are missing is that these composite tails have a history. Have you forgotten the litres of water drained from AA Airbus tails/ have you forgotten the issue of internal collapse of the structure due not just to oil based contaminants, but also the effect of repeated freezing and expansion in flight cycles of ingress affected composites.
And what about the manufacturing flaws - flaws over and above a critical size. Who is going to look for those. What about the repaired new fins that are alleged to have existed.
The cause of this accident remains unknown. until we know ALL the facts, we will never know what happened as a casue or a consequence.
Best wait until then before we unpack past accidents and past debates.
