Two separate incidents. Not enough detail on either to make a link, IMO.
Sad though these are, the reports add nothing to our understanding with little more than the comments of the neighbours.
I'm not aware on Canadian certification requirements, nor standards pertaining to homebuilts, so would be more interested to see a link to the full reports.
F11? Ah, a sort of D11 copy. I've found this from a quick search: "All in all, the Falconar "Jodel" should not be looked upon as a Jodel, but as a Falconar. This is either good or bad. Just a fact to take into account".
