The investigation seems to view it as a manufacture fault, maybe they have other info that corroborates that view. If it is faulty to start with, then surely misalignment would
result in a poor connection, which would then lead to more vibration of the connection, then leading to failure as you state. Or maybe cause and effect as you state. Chicken - egg.
Would be nice to have pictures of the whole pipe assembly - I still feel we're only looking at half (or less) of the picture.
