It is composite, but with a wooden core. The failure occurred near the
counterweights at the hub, and they haven't found the bolt, I gather. The
story that someone has concocted (I hear) is that the propellor suffered a
lightning strike sometime in the past and the failure was a (distant) result.
But, perhaps coincidentally, we have stopped flick manoeuvres in aerobatics.
Another story goes that the manufacturer, Grob, was upset to find that we were
performing these manoeuvres during aerobatic sequences: they cause a fair bit
of stress to the airframe and perhaps to the propellor.
Aeros will be a little less dynamic from now on . . .
