INSTALLATION APPROVAL NOTE
Presently, no TSO standard exists for airborne FM transceivers. 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) Approvals
(both US and Canadian) on its Airborne FM products for many helicopters currently being delivered
in the US and Canada as well as a number of single engine fixed wing aircraft. The above
referenced DO-160C test data is also on file and available from Technisonic to support approval
requirements in airframes for which Technisonic does not possess an STC.
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 authorized factory dealers/installers are permitted to download and
make use of these documents on behalf of their customers (end users) in support of regulatory
agency approval. Please refer to the Technisonic web site www.til.ca for the latest issue of
available STCs and letter of authorization for use.
