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.
