I remember during an earlier discussion on the construction details of the main Rotor that I referred to a lightning strike report on G-BHBF in 1999 which gave a very good description on the rotor structure .... I asked if G-BHBF was in fact the same aircraft that was lost in the current incident but was told correctly that it was not! ....... just noticed in the AAIB report that in fact the failed rotor component was indeed the same item hit in the 1999 incident ...... its a small world I guess!
