Nubian, can't agree more! With Jet A1, a bit of grease 8 for the hyd pump and droop ring and a split pin or 2 a 350 will run a ver.........................y long time-so will the 130! Quoting a engine price is valid, but I have been operating with a fleet of 350's, 130's and 120's and unless we stuff it up those parts on Turbomeca's side and especially EC have a long life and unbeatable reliability so I guess one can expect it to cost a bit of money. The scheduled maintenance if done in accordance with the manufacturer Maintenance Program is a breeze due to the margins allowed and a machine should never be grounded unless prefered for these? I stand by these machines despite the French telling you if you do have a problem "it's impossible".
