so Steve says:
...We are aware it at least has massive TCAS issues with every component replaced and unable to fix. That may be the reason it is on the deck but the issues with a heavy landing are still circulating. It could almost kill the 787 if true so the security and secrecy over the matter would be a high priority.
If there was a heavy landing, it would be a skill/judgement issue for the drivers - certainly not rare, but not common either - and could happen on any aircraft on any given day. Certainly not likely to "almost kill the 787" as a type.
If there is a TCAS wiring fault, is it a loom design fault, a manufacturing fault or a one-off connection fault that is apparent statically or only when the airframe is dynamically loaded? Of those options, only the loom design fault would have any lasting impact on the reputation of the design. Given that there are quite a few 787s flying around at the moment, whatever it is seems unlikely to satisfy Steve's "almost kill the 787" throwaway line.
If we are that desperate to trash something, I think it is much better fun trashing management rather than aeroplanes or front line people
