    UNIT STANDARD NOTES 
    Supplementary Information

    The Engineering Technician performs three levels of maintenance, namely "O', "I" and "D" maintenance.

    "O" Level maintenance. (Operator level maintenance) is carried out by maintenance and operator staff. Equipment fault diagnosis and restoration of service by reconfiguration will be by means of supervisor positions and remote control and monitoring equipment.

    "I" Level maintenance. (Intermediate level maintenance) is carried out by maintenance staff at the sites and the local workshop. Routine preventive maintenance is also carried out on the systems and corrective fault diagnosis, down to module (LRU) level where faults are rectified through module replacement. Only limited repairs to modules where PCB replacement is possible or where a low technology is required will take place at this level. This level of maintenance includes maintenance to the buildings at the site as well as the site itself such as the roads, grass cutting, fencing, aerials, power and communications from the point of supply.

    "D" Level maintenance. (Depot level maintenance) This covers software and hardware and where faulty modules are returned to the central workshop depot, Supplier or their agents for repair/exchange.

    Routine maintenance schedules have been prepared and are in place for each system based on manufacturers' recommendations, operational requirements and support requirements determined from actual field experience during the operational life of the systems.

    International Civil Aviation Organisation (ICAO) recommendations publishes recommendations and standards for all communications, navigational and surveillance systems used in aviation. The ICAO Annex 10 publication includes the recommendations and standards for communication systems.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
