Appointment of Dealer as Authorized Dealer and Installer

STC Group hereby appoints Dealer as an authorized, independent, non-exclusive Dealer for the sale and installation in certificated aircraft of hardware designed by STC Group and manufactured pursuant to FAA standards (Installation Kits).  The STC Group holds one or more Supplemental Type Certificates (STCs) for the Installation Kits which permit the installation in specified, certificated aircraft of autopilot control units, servos and related wiring and software (Autopilot Systems) manufactured, marketed and separately warranted by Trio Avionics Corporation (Trio), 1905 N. Marshall Avenue #6, El Cajon, CA 92020.  As used herein Autopilot Systems means and refers only to those autopilot control units, servos and related wiring and software manufactured by or for Trio for use under the authority of Supplemental Type Certificate(s) held by the STC Group and not to any components of the Installation Kits. As used herein, Autopilot Systems does not mean or refer to autopilots manufactured and marketed by Trio for use in non-certificated aircraft, including amateur-built/experimental aircraft.


STC Group’s Relationship with Trio Avionics Corporation Trio sells its Autopilot System directly to each end user customer or a Dealer on the condition that the purchaser or Dealer (1) obtain a Supplemental Type Certificate for the intended aircraft and authorization to use the same in that aircraft from the STC Group, (2) obtain and use an Installation Kit and approved hardware from the STC Group, and (3) agree to install and use the Autopilot System in compliance with the Installation Instructions and Instructions for Continued Airworthiness provided by the STC Group.  All other terms and conditions of sale of the Autopilot System, including the provision of warranty service for the same, are determined separately by Trio.  Conversely, all terms and conditions of sale of the Installation Kits, including the provision of warranty service for the same, are determined separately by the STC Group.

 STC Group’s Obligations to Dealer

STC Group will provide Dealer or Dealer’s end user customer with technical assistance in the installation of all Installation Kits.  The STC Group will also provide Dealer or Dealer’s end user customer with technical assistance in the inputting of initial autopilot settings.  All issues involving software adjustments or calibrations not remedied by standard or basic installation protocols will be referred to Trio for resolution. Both STC Group and Trio will provide Dealer with promotional material such as product literature, or advertisements.   Dealer shall at all times be a sales agent for STC Group and should not hold itself out as a partner of, or joint venturer with STC Group.  

Dealer Obligations

Dealer will promote the sale of Autopilot Systems and the related Installation Kits and will, at all times, conduct business in a manner that reflects favorably on STC Group and Trio, and on the safety, reliability and utility of the Autopilot Systems when installed and used in accordance with the STC Group’s Installation Instructions and Instructions for Continued Airworthiness.  Dealer may set its own price for the sale and installation of Installation Kits.  Dealer will advise and instruct all purchasers of Installation Kits of applicable FAA-approved installation instructions (ICs), Instructions for Continued Airworthiness (ICAWs), the need to comply with all ICs and ICAWs and STC Group’s requirement that it be notified promptly of any difficulty reports relating to the installation or operation of any Autopilot System. Dealer will advise and instruct all purchasers of Installation Kits that all warrant issues involving the Autopilot System, as contrasted to the Installation Kit, should be referred to Trio.   Dealer agrees to support and assist customers with learning and understanding the features of the Trio Autopilot System.  Such support at a minimum should include providing customers with a copy of STC Group’s approved training overview video.   Before accepting any aircraft for installation of an Installation Kit, Dealer will perform an inspection of the basic airframe structure and specifically of all control surfaces, control cables and related components.  Dealer will not install an Installation Kit in an aircraft that will be released to service with a known condition that renders it not airworthy.  Among other items, Dealer will inspect the pitot-static system of each aircraft before and after installing an Autopilot System.  No aircraft should be returned to service if the pitot-static system shows leaks or other defects making it not airworthy. In all cases, no certificated aircraft will be returned to service with an Installation Kit installed unless and until the appropriate entries have been made in the aircraft’s logs returning it to service as airworthy.   In order to give STC Group a first opportunity to review and remedy any problems or issues with its Installation Kits and without limiting Dealer’s right to report any defect, condition, problem, hazard or other issue involving the Installation Kits that might affect the safety of flight to the relevant regulatory entities, owners or aircraft operators, Dealer agrees to give STC Group prompt and detailed notification of any such defect, condition, problem, hazard or other issue before publishing the same to the general public.   Dealer agrees it shall only use approved artwork in advertising.

Dealer shall advise retail customer that the applicable STC and ICAW require the use of STC Group/Trio original equipment parts and accessories (OEM) manufactured under STC Group’s/Trio’s respective PMA authorizations in the installation, repair and/or replacement of Installation Kits or Autopilot Systems. Dealer shall advise retail customer that autopilot systems and parts manufactured by Trio for use in experimental/amateur built aircraft (non-PMA Trio parts) may not under any circumstances be substituted in certificated aircraft for OEM parts.  All invoices used by Dealer for the sale of non-PMA Trio parts shall conspicuously sate “Not for Use in Certificated Aircraft.  Voids Applicable Supplemental Type Certificate Making Aircraft Not Airworthy”.  Dealer shall not represent non-OEM parts as STC Group or Trio OEM parts, or offer non-OEM parts for use in certificated aircraft.
