First up im a newbie and this tragedy brought me here.
Condolences to the families and all those involved.
For what it is worth I was trained in that aircraft and it was a good one when it was at airborne, I liked it.
Having had a brief look at the flight tracking info on this accident it makes little sense to me and we will wait for the investigation.
With the flap issue pointed out in this post by
Deaf that does make some sense, i was taught based on my memory, after downwind do a gumps check abeam the runway, set 1500 rpm, 10deg of flaps, trim wait for 80 knots or 45deg to runway and turn base.
It would seem whatever befell this poor student would have happened somewhere when I was trained about when flaps 10 were selected.
This is all without evidence of course and not worth much but I felt compelled to share.
