Hi there
Makes you wonder what does justify the title of "operational", then?...........I well remember inhibiting the Lycomings.I also remember the shuffling around of aircraft when the IRANs were coming up, to get the highest-houred (engine) ones in line for the IRAN, so as not to waste hours.........Agusta were a pain in the arse for spares.Their support was dreadful.
