There are perhaps 3 senarios inplay here:
1) The FO bounced the plane and then touchdown with a very nose high , low energy state. Perhaps -15 below Vapp. Tailstrike.
2) The FO bounced and the Captain took over. Then as above , tried to arrest the sink rate with a very nose high pitch . Tailstrike.
3) The Captain took over at some stage and ultimately failed to initiate the missed approach and his none SOP actions caused the subsiquent tail strike .
Of note is the fact the FO was a former long time 330 operator new to the 321. He had recently missed out on command. A reason the commander should have had his thumb on the red take over button?
As mentioned above , the captain is a senior instructor.
As also mentioned , its fairly normal in ka for instructors to bark and holler in simulators. Arrogance prevails from the instructors seat . De briefs dwell on splitting of hairs and minor errors on a sim check .
FOs are scapegoats for the errors of their captains.
When an instructor in KA is responisble , whether they are well respected or otherwise, its only natural for the silent majority to quietly smirk and think , time to swollow your own medicine.
Ultimately this accident will be brushed under the blanket of incidents that KA contiune to get away with. Recent events inc the 2.8G landing, where ultimately a manager flew back from Penang at FL150 , gear down were never really mentioned in the safety review. How much fuel did that cost? Conviently not mentioned .
And then there was the emergency breach of the FTLs last year by the management pilots wife. Result, nothing . She continues to ply her trade and continues to exhibit fuel compromies. Most local FOs will not fly with her.
Will there ever be a true and level playing field in KA for the regular line pilots? Unlikely. Very unlikly.
