ADAPTER PLATE (ACK) Part Number 103059 Installation Instructions
Overview
Trans-Cal Industries Adapter Plate part number 103059 allows the avionics
technician to quickly replace existing ACK 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 ACK mounting tray. The adapter plate is
manufactured from .062” thick aluminum with 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 103067)
