Technisonic airborne products can be approved for installation in fixed and rotary wing aircraft via the following methods.

ACCESS/A audio controllers are TSO’d and are therefore eligible for installation into any aircraft. This certification facilitates a nice, clean and simple installation approval as most regulatory agencies worldwide recognize TSO compliance and all that such certification represents.

We are not quite so lucky however when it comes to installing airborne FM transceivers into aircraft. Presently no TSO standard exists for airborne FM. To make it easier for installation agencies to provide their customers with an approved installation supported by an effective Airworthiness Approval, Technisonic has secured Supplemental Type Certificate (STC) Approval (both US and Canadian) for most helicopters currently being delivered in the US and Canada as well as a number of single engine fixed wing aircraft. Approved aircraft types are listed in the attachments to the formal STC documents. These STCs are the exclusive property of Technisonic and require the written authority of Technisonic for their use. To assist Factory Authorized Technisonic Dealers in the certification process, we have placed copies of our Canadian and US STCs on our web site along with a letter of authorization for their use. These documents may be downloaded and used as support for the technical submission to FAA or Transport Canada. Only factory authorized dealers are permitted to download and make use of these documents on behalf of their customers (end users) in support of regulatory agency approval.

All documents below (including drawings) are in PDF format.
