I thought the fatigue life of each type was assessed by assumed usage spectra, which took into account the frequency of reaching different g levels per flying hour. This lead to some issues when the DA granted a life to a new operator on the basis of exchange rates for existing operators. Again, surely fatigue stats for sqns are monitored to optimise usage of individual airframes, so aren’t those stats fed back to individual pilots as in "Prune, you are becoming unaffordable"
