2.4 Servicing Information
In the event of a G600 system, GNS 530W, GNS 430W, GMA 347, or GTX 330D failure, troubleshoot the
unit(s) in accordance with Appendix A of the appropriate Modification Summary. In the event of a GMX
200 or WSI AV-200 failure, troubleshoot the unit(s) in accordance with the Installation Manual for that
unit. The Garmin GA 35 GPS Antennas, Comant CI 105 Transponder Antennas, and Comant CI 1530-1
WSI Antenna are non-repairable; in the event of a failure, the antenna must be replaced.
2.5 Periodic Maintenance Instructions
Maintenance of the components installed by this STC is on condition, except as noted in the following
table.
Item Description/Procedure Interval
GRS 77 AHRS
The GRS 77 utilizes an Earth magnetic field model which is
updated approximately every five years as part of the Aviation
Database maintained by the owner/operator. If the magnetic
model is not current, the unit will issue an alert upon startup
indicating the model has expired. The model can be updated by
inserting an aviation database card in the GDU 620 with an
updated IGRF model and powering on the system. A prompt will
direct the user to press ENT to update the model.
On condition
GDC 74A ADC
Test according to 14 CFR Part 91.411 and Part 43 Appendix E.
See the pitot-static checkout procedure in Section 5 of the
appropriate modification summary document.
The tests of Part 43 Appendix E sub-paragraphs (iv)
(Friction) and (vi) (Barometric Scale Error) are not
applicable because the digital outputs of the GDC 74A are
not susceptible to these types of errors.

Antenna
Conduct a visual inspection of the antennas and their mounting.
Verify there are no cracks on the antenna, no cracks or
deformation in the mounting structure around the antenna, and
that all sealing fillets around the antennas are in good condition.
If the antenna is broken, cracked, or dented it must be replaced.
If the attachment is not secure, or the antenna seal shows signs
of damage or decomposition re-attach antenna as described in
section 2.7.7.2 (GA 35 antenna) or section 2.7.10.2 (WSI

Conduct a visual inspection (look for signs of wear, deterioration,
or damage to wires, backshells, or connectors) on units and their
wire harnesses to ensure installation integrity:
1. Gain access to LRU (see General Arrangement Drawing
for LRU locations)
2. Inspect each unit for security of attachment.
3. Inspect all knobs and buttons for legibility.
4. Inspect condition of wiring, routing and
attachment/clamping.
5. Inspect integrity of shield terminations.
6. Inspect for signs of corrosion on equipment and rack
