GTX 23 Installation Manual

Rev. C

Page 3-2

The GTX 23 connector kit includes one Garmin backshell assembly.  Garmin’s backshells give the installer 
the ability to quickly and easily terminate shield grounds at the backshell housing.

Refer to Appendix B for Shield Block Installation Instructions.

Weight and balance computation is required after the installation of the GTX 23.  Follow the guidelines as 
established in AC 43.13-1B, Chapter 10, Section 2.  Make appropriate entries in the equipment list 
indicating items added, removed or relocated along with the date accomplished.  Include your name and 
certificate number in the aircraft records.  Section 1.7.1 identifies the weight of the new GTX 23 
equipment and the drawings in Appendix D shows the center of gravity.

An electrical load analysis should be completed on each aircraft prior to installation in accordance with 
AC43.13-1B, Chapter 11.  Use the following values for computation:

1) Non-Garmin part numbers shown are not maintained by Garmin and consequently are subject to 
change without notice.
2) Extracting the #18 or #20 contact requires that the expanded wire barrel be cut off from the contact.  
It may also be necessary to push the pin out from the face of the connector when using an extractor due 
to the absence of the wire.  A new contact must be used when reassembling the connector.
