I wonder what the time scale is for going back to original design shafts on the L and L2 models. I also wonder if it is possible to rework the existing new design shafts which are in service now or will EC have to start from scratch. I assume it takes a long time to make a shaft due to the manufacturing, chemical treatment and ageing processes involved so the North Sea (and other areas) is probably in for a lengthy disruption.
The loss of a significant proportion of O & G helicopter support worldwide is bound to cause serious concern at the highest levels of the oil companies management and governments.
