Imabell :
I scan the BASI web pages on a reasonably regular basis, and haven't seen accident reports for those incidents you mention.
This doesn't mean that I don't believe you - in fact the opposite - but if you know of a web source for accident reports, could you post it ?
As an aside, I find the attitude of BASI a little incomprehensible sometimes. Last year ( if I remember rightly ) a H300 crashed with two fatalities in the Vic mountains but NO accident report followed ( apparently they were too busy ). But a Brantly which ran out of fuel merited a full accident report. Odd.
