Installation and Set-up
  • Each aircraft receives a detailed preflight and flight inspection to
    ensure airworthiness and to document performance of instruments, flight
    controls, landing gear, accessories, lights, and avionics.
  • Discrepancies are brought to customer’s attention. Non-airworthy items must
    be repaired at customer’s expense during RAM proceedings in order for RAM
    to set up, fly, and deliver the finished product.
  • Old engines are removed. Engine beds are cleaned. Mount structures are
    inspected and corrosion treated. Four hours labor per engine is standard.
  • Due to its tendency to contaminate the engine oil supply, if installed, the
    propeller unfeathering accumulators will be disabled unless optionally
    replaced with a newer unit. OHE: $875 / each
  • Applicable RAM R.O.I. Installation Parts and Upgrade Kit are installed.
  • Engines installed & setup, involving multiple flights and fuel.
