... The investigation so far has shown that the accident was the result of a fatigue fracture in one of the eight second stage planet gears in the main gear box, a failure with clear similarities with the crash off the coast of Scotland in 2009 with G-REDL. The fatigue crack developed without this being captured by the existing required or supplementary warning systems.
Where does that take us?
Shy of small enough bits breaking off the Gear is there anyway the existing detection and monitoring systems would ever work to prevent such a thing from leading to a Catastrophic failure?
