Hi.
All of these losses are reported in the loss records for Schulen und sonstige Verbände, October 18th 1941:

I would say that two of these aircraft can be stated to have been combat losses, to ay that the reason for the last aircraft being wrecked by landing was battle damage would be speculation (and these guys wrecked their 109's at a tremendous rate.... in landing and take-off accidents).
So I guess mystery solved, these aircraft were from the operational Staffel of a fighter school, not a frontline unit. I am not implying that the quality of the pilots necessarily was inferior to the ones in a frontline units, some of the teachers in these schools were rather experienced.
Best regards,
