1. Preface
1.1 Purpose
This document provides guidance for those planning to install a Trig TY96/97 VHF Radio under CS-
STAN, Subpart B CS-SC001a.
1.2 Scope
CS-STAN Installation of VHF is applicable to any Non-complex motor powered EASA Aircraft, with
a maximum cruising speed in ISA conditions below 250kts, non-complex rotorcraft and any ELA2
aircraft. Non-complex as defined in https://www.easa.europa.eu/easa-and-you/general-
aviation/operations-general-aviation
Complex motor-powered aircraft’ shall mean:
(i) an aeroplane:
with a maximum certificated take-off mass exceeding 5 700 kg, or
certificated for a maximum passenger seating configuration of more than nineteen, or
certificated for operation with a minimum crew of at least two pilots, or
equipped with (a) turbojet engine(s) or more than one turboprop engine, or
(ii) a helicopter certificated:
for a maximum take-off mass exceeding 3 175 kg, or
for a maximum passenger seating configuration of more than nine, or
for operation with a minimum crew of at least two pilots, or
(iii) a tilt rotor aircraft;
1.3 Limitations
CS-STAN cannot be used to extend the operational capability of the aircraft, ie: VFR upgraded to IFR.
New installations are limited to VFR operation
An existing IFR radio can be exchanged with a replacement IFR radio.
In the case of rotorcraft approved for NVIS, if cockpit panels are to be inserted, the change cannot be
considered a standard change.
1.4 Changes from Previous Issue
None, this is the first issue
1.5 Changes Forecast
None.

2. Introduction
This guide describes the process of installing a TY96/97 VHF radio, using the EASA document
‘Certification Specifications for Standard Changes and Standard Repairs’, more commonly referred to
as CS-STAN. EASA delivered CS-STAN as a more affordable and much faster alternative to the old
EASA Minor Change process
CS-STAN removes the need for any interaction with EASA to complete the change, and no EASA
admin fee. CS-STAN can be used to complete a wide variety of installations, including transponders,
radios, antenna, moving map systems… the list goes on.

3. Change Details
3.1 Description of Change
This change involves removing an existing radio if applicable, and installing a Trig Avionics TY96/97
VHF Radio.
The processes involved in the change includes pre-testing of any existing installation; verification of
the suitability of the existing power supply wiring; installing the TY96/97 and post-installation testing
as defined in the TY96/97 VHF Installation Manual.
If replacing an existing radio; the original mounting tray will need to be removed and the dedicated
TY96/97 tray must be installed. The connector will also need to be replaced. The existing antenna can
be re-used –provided it is in serviceable condition. Otherwise, need to be replaced or repaired. An
antenna can be replaced under the CS-STAN Section CS-SC004a.
3.2 Radio Selection
The minimum output power specified for the radio is sufficient for the operation depending on the
maximum flight level of the aircraft. The table below is valid for standard antenna installations antenna
type and position) with standard cable length less than 4m and 2 connectors.

For different installations (cable length, connectors), the required output power needs to be assessed by
additional analysis.
For aircraft flying below FL250 the TY96 (nominal power of 10W) is sufficient. For aircraft flying
above FL250 and up to FL400, the 16W TY97 Radio must be installed.
3.3 Acceptable installation methods, techniques and Practices
The installation and return to service test must be carried out in accordance with the TY96/97
Installation manual, available on the Trig website at http://www.trig-avionics.com/products/ty96/
The TY96/97 meets all requirements of CS-STAN as laid out in Section 3 of CS-SC001a; certified to
ETSO 2C169a, capable of both 8.33KHz and 25Khz spacing.
In CS-STAN, It is stated that the installer must ensure that the radio is suitable for environmental
conditions to be expected during normal operation. The TY96/97 is certified for wide variety
environmental stress, as detailed in the TY96/97 Installation Manual.
3.4 Continued Airworthiness Instructions
An approved aircraft maintenance program will normally include periodic functional checks of the
communications radio installation.

______________________
Trig Avionics Limited Page 6
Other than for periodic functional checks required by the regulations, the TY96/97 VHF Radio has
been designed and manufactured to allow “on condition maintenance”. This means that there are no
periodic service requirements necessary to maintain continued airworthiness, and no maintenance is
required until the equipment does not properly perform its intended function.
3.5 Acceptable Means of Compliance
The Installation must be carried out by an EASA Part M or EASA Part 145 organisation. The work
required includes an entry in the aircraft log book and the completion of a Form 123. Below is an
example of the Form 123, which can be used as a template;
3.6 Form 123
The original Form 123 remains with the legal or natural person responsible for the embodiment of the
SC/SR. The aircraft owner should retain a copy of this form. The aircraft owner should be provided
with copies of the documents referenced in box 6 marked with an asterisk '*'.
