I think the real thing was 'they didn't know what they didn't know' hence the blanket grounding while they baselined the situation. That meant a survey of each airframe - no small task.
You can kind of understand that.
I was concerned about the supposed lack of documentation of the repairs and the poor quality of some repairs (just paraphrasing some comments on this thread). Weren't the repairs all done 'in house' by the GRP bay at Syerston ?
