A “flying wire” broke and was witnessed “hanging down” by the pilot. The flying wires affect the lateral stability of the floats. It was not a broken bracket at that point.

Hmm, I haven't flown any form of Rans S7S, but from pictures the 'fly wires' seem to be very out of sight from the cockpit seated positions. Flying/Fly wires being the cross over wires bracing between the struts on the floats. Which on the S7S are below the seat of the pilot. If it had the full door windows or open doors I might understand, but with the smaller windows It seems hard to see such fittings.
