California Power Systems now carries Rotax 912 engine rubber replacement kits. These kits are furnished with the parts most commonly needed for the five-year engine service requirement. They were developed by Roger Lee for the Flight Design CT, but they will also work for other aircraft. Just re-measure the fuel, oil, and coolant lines for lengths needed on different installations. If other lengths are needed, contact CPS before ordering, as the parts will need to be ordered individually instead of by the kit part number.
