I'm flabbergasted that some here think that this incident was in any way related to or as a result of the late selection of flap 40, or the handover of control.
The FDR clearly shows that the aircraft was, and remained throughout, just about on the profile and also pretty close to the target speed - until the last 100 feet or so. It was only then, WAY after the flap 40 selection, that things started to get out of shape.
Using the logic of the author of this report, I'm surprised that he didn't look back even further and study just what SOPS the crew might have busted while flying the departure!
The fact of the matter is the FO screwed up at a very late stage in the approach. The Captain warned him that things were getting out of shape, and then she screwed up the recovery after she had taken control. It was a clusterfkuc, but of course the report can't simply state that....it MUST find a reason.
All of us make a bad landing from time to time...and many times we can't explain why. Often times there is no explainable reason, but of course the NTSB have to find some tosh to write....and that is exactly what they did this time.
