The free-wheeling outer race was outside the manufacturer’s specification for roundness. This, over time eventually, resulted in slippage of the spraggs, the end result being the shearing of the stub shaft. This effectively disconnected the engine from the drive train with no indication to the crew of the actual problem and resulted in an out of control condition from which they could not recover.
