ADAPTER PLATE (Sandia) Part Number 103035 Installation Instructions
Overview
Trans-Cal Industries Adapter Plate part number 103035 allows the avionics
technician to quickly replace existing Sandia altitude encoder installations in
favor of Trans-Cal’s SSD120-(XX)N(X)-(X). This adapter simplifies the
mechanical installation task by providing a mounting plate designed for the
SSD120-(XX)N(X)-(X) while utilizing the existing Sandia mounting tray. The
adapter plate is manufactured from .062” thick aluminum with a chem-film
treatment to inhibit corrosion. The adapter is shipped with stainless steel
fastening hardware to secure the digitizer to the plate.
Please note:
The SSD120-(XX)N(X)-(X) and this adapter plate are approved under TSO-C88a
and ETSO-C88a. It is the responsibility of the installer of this equipment, within a
specified type or class of aircraft, to determine that the aircraft operating
conditions are within TSO or ETSO standards.
Assembly and Installation Instructions (Refer to TCI Drawing 103081)
1. Secure the altitude digitizer (item 1) to the adapter plate (item 2) using four
flat head screws, lock washers and nuts (items 3, 4 and 5) as shown on

(item1) as per the digitizer installation instructions.
3. Place this assembly into the existing Sandia mounting tray (item 7) and
snug the Sandia retaining knob (item 6) to secure the unit to the tray.
