No Great Shock
This is a semi-new airplane with slightly different weight and balance numbers. Tail strike testing was/is on the list, but they got a head start. While no fan of the AB320 series, I'm not worried that it is unsafe. Nuts. AB and the several certificating agencies will obtain and publish the relevant AOA numbers in due time.
A recordable event? Yes. The DFDR data will help the engineers and test pilots proceed through their testing. A panic event, worthy of screeching media attention? Not even close. Record numbers, adjust as necessary and proceed with certification. Duh?
