Robinsons provide lower cost flying often to schools with many hours from novice pilots. They set their component and TBO time to allow safe operation but at low cost. The regulators when agreeing the schedules do this on the basis they will be strictly adhered to. Maintenance should never, never be neglected on helicopters it might kill you or others. Bear in mind there are some on this forum who would be nervous flying such a type even if had been meticulously maintained.
