It looks to me like there might be a lot of right rudder
applied, possibly by a frightened passenger, and the pilot is using
left aileron to counteract it. The overall drag gets too high and
brings the airplane down in a marginal DA and gross weight situation,
maybe aggravated by a distracted pilot trying to get the passenger off
the pedals.
Just a guess, but there's a frame or two where the rudder
looks cocked right.
