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.

Most of the Collins Proline I components were originally manufactured in the early 1970s. Collins has continued to produce some of the Proline I components by special order over the past 30 years however large scale production stopped many years ago. Most of the Collins Proline I product lines incorporates 1960s and 70s analog technology. Collins has superseded the Proline I product line several times with the Proline II, Proline IV, and Proline 21 lines. As a result, some service parts needed to maintain and repair original Collins Proline I components are no longer available. Therefore, you may experience limited to no warranty available and unreliability for many of the Proline I units.
