ADAPTER PLATE (TCI D120) Part Number 103036 Installation Instructions
Overview
Trans-Cal Industries Adapter Plate part number 103036 allows the avionics
technician to quickly replace existing TCI altitude encoder model D120-P2-T
installations in favor of the latest model 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 D120-P2-T mounting
hole pattern. 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.
