RANS S-9 Chaos loses a wing

I'm working for a German ultralight manufacturer (whereas European
ultralights compare more to US LSA than to US ultralights), and all
our aircraft are required by law to have a BRS installed. We've had
several of our customers come down safely under a 'chute.

Of course it is preferable to never have to use a recovery system.
Events like wings folding, control systems breaking or similar are
very rare. In most cases where the BRS has to be used, it's when the
engine quits _and_ there's no place to safely make an emergency
landing, like over water, forest or swamp.

Even if you have a BRS installed, it is advisable to try an emergency
landing in a suitable field, since very likely the structure of the
airplane will suffer less damage. As someone pointed out, the airplane
comes down nose first, usually with a speed of about 5-6 m/s (15-20 ft/
s). That can break a lot of expensive stuff (prop, engine, fuselage).
In an emergency landing, done properly, you may only have to replace
the landing gear and cover up a few bruises on the fuselage.
