Apologies - I take your criticism onboard. That "jibe" was "toungue in cheek"; I am sure that the German program is just as rigorous as elsewhere in Europe.
I have no problem with observations that in this instance it was a landing that he "might" not have been allowed to make (I am sure that the point will be covered in the investigation), and hence that he was rule- braking. The thread seems to me to be drifting into a "CPL v PPL" bashing. My only point was that trained pilots who stay within their limits are safe. Pilots who fly outside their limits (well trained or not, CPL, PPL, ATPL) are unsafe. Off-airfield landings are no different. They bring different pressures, that's all.
So, in my (humble?) opinion, he crashed because he flew into a power line. Failing to be aware of and to deal with the power line was the element of poor airmanship. There are quite a few examples of PPLs and CPLs doing the same.
