This section presents the instructions for continued airworthiness, as per FAR 25.1529, of the 
HSD-400 Satellite Terminal. 

Installation of the HSD-400 terminal on an aircraft by supplemental type certificate (STC) or

this manual in the operator's Aircraft Maintenance manual and the operator's Aircraft

The following paragraphs describe all maintenance requirements and instructions for

If an HSD-400 terminal is inoperative, remove the terminal, secure cables and wiring, 

collar applicable switches and circuit breakers, and placard them as “inoperative.” Before 

flight, revise the equipment list and weight and balance data as applicable and record the

approved for return to service. All special tools required to test the terminal for approval 

for return to service are listed and described in the Test and Fault Isolation section of this 

manual. Approval for return to service must be entered in the logbook as required by
