Negotiating the exchange price of a unit only limits the allowable repair cap for the core unit. Southeast Aerospace's exchange transactions are based on the return of economically repairable core unit. Once the core is received and evaluated, the core repair cost incurred by SEA cannot exceed 80% of the original exchange price. That is, it cannot cost SEA more than 80% of the original OH/SV exchange price collected from the customer. Therefore, when and if an SEA exchange price is discounted, there is a risk that additional charges may be assessed once the core is returned and evaluated.

The CTL-X0 is 30-40 years old. Service parts from Collins are either no longer available or extremely expensive. It is not cost effective nor possible in some situations to continue to utilize the CTL-X0 controls in your aircraft. Southeast Aerospace recommends converting the CTL-X0 controls over to the Collins CTL-X2 Proline II controls.

The CTL-X2 is not a direct replacement for the CTL-X0 controls. A connector change, CAD adapter, and locally fabricated panel filler plate are required for the change. A qualified avionics technician should perform this modification. While this is a moderately involved retrofit, it is a change that is eminent and will ultimately be required if you continue to use your original Proline I radios.

• To convert from the CTL-20 Comm control, the CTL-22, CAD-31, mating connectors, and CAD bracket are required.
• To convert from the CTL-30 Nav control, the CTL-32, CAD-31, mating connectors, and CAD bracket are required.
• To convert from the CTL-60 ADF control, the CTL-62, CAD-62, mating connectors, and CAD bracket are required.
• To convert from the CTL-90 Transponder control, the CTL-92, CAD-62, mating connectors, and CAD bracket are required.

For an exact SEA quote to convert from your CTL-X0 control, please provide the part number of your CTL-X0. Contact SEA with this information and an SEA rep will provide a quotation immediately.
