15.5 Unit Installation

Fabrication of a wiring harness is required. Sound mechanical and electrical methods and practices should
be used for installation of the GSA 28. Refer to

Connector kits include backshell assemblies. Garmin's backshell connectors give the installer the ability
to quickly and easily terminate shield grounds at the backshell housing. The instructions needed to install
the Jackscrew Backshell are located in
15.5.1 Pinouts
See Section 23.10 for pinout information.
15.5.2 Mounting Requirements
WARNING
It is vital to ensure the autopilot servo and aircraft control linkage is free to move
throughout its entire range of travel without binding or interference. Failure to ensure
adequate clearance between the moving parts of the control system linkage and nearby
structure could result in serious injury or death. If any control system binding or
interference is detected during installation or preflight inspection, it must be corrected
before flight.
CAUTION
Do not mount the GSA 28 on the 'hot' side (engine side) of the firewall, or in any location
where it would be exposed to radiated heat from the engine.
15.5.2.1 Optional attachments
The GSA 28 is supplied from the factory with a standard crank arm attachment
Figure 15-8.1, Figure 15-8.2, and
011-02952-10 RV-6 roll kit and a capstan attachment available in the 011-02952-02 Capstan Kit. If one of

replace it with the optional attachment. When removing the standard arm, keep the castle nut, lock washer,
