I reckon he’s talking about the JQ TOGA tap incident at Melbourne??? Musta been 10 years ago? Very vague memory of it!
If that is what he is talking about then it had nothing to do with coming off another type! It had a lot to do with not understanding modes (common to Boeing and Airbus). If it is something else I would really like to know the circumstances as I would want to know what someone coming off a 787 could do on an Airbus that could cause a near catastrophe.
The TOGA tap incident was, hard to believe, 16 years ago.
