In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.

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.
