MAINTENANCE AND REPAIR
This section provides maintenance and repair information for the A781-200 system, including the
following sections:
• Maintenance
• Repair
• Instructions for Continued Airworthiness
• Visual Inspection and Check
1. Maintenance
The A781-200 system does not require routine maintenance.
2. Repair
If functional problems occur, the SDU BITE identifies the faulty LRU.
As per continued airworthiness instructions, if an SDU or SCM is inoperative, use the Standard
Practices Chapter of the Aircraft Maintenance Manual to:
• remove the unit
• 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 removal of the unit in the log book [refer to section 91.213 of the FAR or the aircraft’s minimum
equipment list (MEL)].
All repairs must be performed at the RCI equipment supplier factory.
3. Instructions for Continued Airworthiness
Periodic inspections of the mechanical and electrical interfaces of the A781-200 system
components to the aircraft should be completed as defined by the governing airworthiness
body’s Instructions for Continued Airworthiness (ICA) for the installation (for example, Transport
Canada, the FAA, the EASA).
Installation of the ARINC 781 SATCOM Avionics System on an aircraft by Supplemental Type
Certificate (STC) obligates the aircraft operator to include the maintenance information supplied
by this manual in the operator’s Aircraft Maintenance manual and the operator’s Aircraft
Scheduled Maintenance Program.
This section provides the special instructions and maintenance requirements for continued
airworthiness of the A781-200 system.
