Maintenance Concept; Factory Repair - Garmin GMA 347 Maintenance Manual

_________________________________________________________________
1.2 MAINTENANCE CONCEPT
The maintenance concept for the GMA 347 is to fault isolate down to board level and return
the audio panel to operating condition. There is no component level repair.
Avionics shop repair is limited to replacing the parts listed in Section 4. All repairs can be made
at the bench with an appropriate replacement spare part. For information pertaining to spares
stocking (suggested quantities, etc.) contact Garmin at one of the addresses listed on the inside
cover.
This manual is written for field shops not equipped with Garmin Automated Test
Equipment (ATE) and not having access to Garmin proprietary repair
documentation. Send the unit to Garmin for repair when any troubleshooting,
testing, or repair falls outside the scope of this manual.
1.3 FACTORY REPAIR
A "Return Merchandise Authorization" (RMA) number must be requested from Garmin before a
unit is returned. Units returned without an RMA will be refused and returned at the sender's
expense. Send units with assigned RMA numbers to the following address:
