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 STC’s 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 STC’s 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/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 STC s and letter of authorization for use.
