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 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.
