There could be more to this than meets they eye at first glance. A Falconar is basically a jodel D11 with a wider steel U/C spaced out on the wing . The trade mark turned up outer panel is closer to the fus with less dihedral.
The structure is basically the same, but the U/C may impose different stresses into the spar because of the way it is mounted.
Basically the Falconar range are well respected and proven aircraft.
The jodel d9 is a single seat aircraft that was designed to 10 g ultimate wing strength. Falconar also do a version of this model.
Some d9's are flying in Europe with light weight two stroke engines as ulm's ( microlights ) but very care full attention to weight whist building is needed. Some people are known to aerobat them regularly.
The d9 in the UK is usually VW powered ( I own one) and heavier and certainly not cleared for aeros.
If it turns out that this falconar was a 9 ( i.e. single seat) that might explain why it was being aerobated. If it was an 11 , then significant weight ( I would say impossible) savings must have been made to register it as a microlight and maybe important structural items where compromised and that could explain why it failed structurally.
Either way it has no bearing on the English ( or French ) fleet of Jodels.
