RAM Overhauled Engine TBO Warranty
100% Engine, propeller, and accessories for the 1st year, or 480 hrs, whichever occurs first. Thereafter, the engine only is warranted on a prorata basis to TBO at RAM’s reduced minimum accrual rate of only 30 hours per month, thus extending coverage over four years. For complete details go to www.ramaircraft.com/ramtbowarranty.

Exchange Core Policy: Engine, crankcase, crankshaft, internal gears, exhaust, accessories, propeller, governor, and hardware items are only sold on an exchange basis, based upon the customer's exchange of like type and normal runout cores as removed from subject aircraft, and serviceable to RAM's overhaul specifications. Cores should be returned within 30 days of RAM OHE engine shipment, or immediately with a RAM installation. Non-serviceable core fees will be due and payable to RAM.
The current replacement cost for a GTSIO-520-H propshaft from CMG is $20,731. We encourage customers to send an overhaulable core replacement if at all possible instead of incurring the core replacement cost if their prop shaft is not overhaulable.

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. Unairworthy 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.
  • Aircraft washed. Interior cleaned prior to delivery and customer acceptance.
