ATC watcher
Then you probably never read an Indonesian investigation report before. (or any other for that matter)
No, but I have read two reports from xxxx nation, which did do everything to blame Boeing. And I have read two reports from xxxx nation, which did exactly the same thing (also to Boeing, but that is merely due to Boeing's commercial reach into those regions).
One interesting preliminary report said that, 'the gear collapsed because the captain landed the aircraft too smoothly....'
So this does happen. Not saying it will here, but it is always in a nation's interest to deflect blame, and the temptation is therefore high. We shall no-doubt see what they say shortly, but the long delay suggests that all is not well between the local CAA and Airbus.
