Well its irrelevant now as we have even more ridiculous things to enjoy...
if I can remove the duals, then I will.
Mate, I really think you should take up a safer hobby. Something like Cross Stitch, maybe.
Can I be so bold as to suggest a completely different sequence of events? The passenger did not lean back to talk to the rear seat passenger and then pull himself forward again by grabbing the yoke. Instead the inputs were from the newly qualified pilot (albeit with a lot of flying in the year since qualifying) who decided to show his work colleague a negative G move, despite having no aerobatic training.
"Here, watch the pencil float off the dash top"
Va, Yoke full back, hold for a second, yoke full forward.
"Sh1t, where's the wing tip gone?"
Just another hypothesis which is equally invalid when talking about allowing your passenger to experience the controls whilst you remain PIC.
Sorry if my dig seems personal but I see no need to sensationalise this debate with irrelevant AAIB reports. Now if you could show me an AAIB report which stated that the Passenger In Command caused the accident I may sit up and listen.
