Primarily for general aviation discussion, but other aviation topics are also welcome.

Can you expand a little? Who wants to submit the paperwork, what kind of paperwork is it and where do they want to send it? I had thought that it was a simple modification of the AFM and maintenance schedule, done by a licensed engineer, but maybe I havenlt understood.

Sorry, still not enough information

CS-STAN can be found here

This is the bit you need, but there are some other notes to read in the main document. Your licensed engineer/CAMO ought to be familiar, and as the doc says, a radio change is not suitable for release to service by the pilot-owner.

Standard Change CS-SC001a
INSTALLATION OF VHF VOICE COMMUNICATION EQUIPMENT
1. Purpose
Exchange of communications (COM) equipment, and for aircraft limited to VFR operation, also installation of
COM equipment. This SC does not include installation of antennas.
2. Applicability/Eligibility
Aeroplanes not being complex motor-powered aircraft with a maximum cruising speed in ISA conditions below
250 kts, rotorcraft not being complex motor-powered aircraft and any ELA2 aircraft.
3. Acceptable methods, techniques and practices
The following standards contain acceptable data:
— FAA Advisory Circular AC 43-13-2B Chapter 2.
Additionally, the following applies:
— The equipment is authorised in accordance with JTSO-2C37d, JTSO-2C37e, ETSO-2C37e, JTSO-2C38d,
JTSO-2C38e, ETSO-2C38e or ETSO-2C169a, or later amendments, or equivalent.
— The equipment is capable of 8.33 kHz and 25 kHz channel spacing.
— 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 4 m and 2 connectors:
Maximum aircraft Flight Level (FL) Minimum output power
up to 100 4 Watts
100 to 150 6 Watts
150 to 200 8 Watts
200 to 250 10 Watts
250 to 300 12 Watts
300 to 400 16 Watts
For different installations (cable length, connectors), the required output power needs to be assessed by
additional analysis:
— The equipment is qualified for the environmental conditions to be expected during normal operation.
— Instructions and tests defined by the equipment manufacturer have to be followed.
4. Limitations
Any limitations defined by the equipment manufacturer apply.
CS-STAN
CS-SC001a
CS-SC001a — 4
The equipment installation cannot be used to extend the operational capability of the specific aircraft (e.g.
from VFR to IFR operation).
In the case of rotorcraft approved for NVIS, if cockpit panels are to be inserted, the change cannot be
considered an SC.
5. Manuals
Amend the AFM with AFMS containing or referencing the equipment instructions for operation, as required.
Amend the Instructions for Continuing Airworthiness to establish maintenance actions/inspections and
intervals, as required.
6. Release to service
This SC is not suitable for release to service by the Pilot-owner

thanks for your reply , according to both the seller of the radio , Trig themselves and a helpful chap at the CAA the trig form does away with the need to carry out the "minor mod " paperwork , just wondered if anyone else has had their installer carry this out ,, and if they charged £200.00+ for filling this out

because apparently it takes 2-3 hours to do the paperwork ,,, ???
