Qoute... Does that mean they have found the missing blade, I wonder?
They may still be looking for it in Germany...
The photo of the fracture seems to reveal the start of a stress fracture at the 10 or 11 o/clock position, in the position of the black marks. Then the fine tree-ring like lines in the 12 o/c position show the repeated cyclic stress failures. Either these occurred every rev of the prop, or it could have been once every-time the prop exceeded a certain amount of torque. (maybe only once per flight.. who knows?)
