Until recently I thought of the Grob 103 as an over-engineered glider,
especially the fuselage and tail. It is quite heavy and I don't have
first hand knowledge of any with broken tail booms. I do know of
several which have been ground-looped without structural damage.

I have heard of, but not seen, G-103's with snapped tail booms.
Locally, over the years, we have had at least two snapped tail booms on
plastic gliders, both from unavoidable groundloops in off-field landings.
It happens.
