Time will tell, but I think it was the US Air Force that used Citation Mustangs at one point and suffered undercarriage issues - modern aircraft are all too lightweight for training,
125 probably too expensive to operate but the Hawker/Nextant 400 is similarly built like a brick outhouse - one of the reasons Nextant chose it for remanufacture and would have been a solid option! Still, Ascent have bought the Phenom, it’s their risk to own. Now, about those CAE/Oxford Air Training shares....
