Unit of competency

Modification History

Release 2. Equivalent to MEA217 Inspect, test and troubleshoot fixed wing autopilot systems and components with amended prerequisite codes.

Application

This unit of competency requires application of hand skills and the use of system/component knowledge and applicable maintenance publications and test equipment to inspect, test and troubleshoot fixed wing multi-axis autopilot systems and components of fixed wing aircraft that have multi-axis autopilot systems, including those incorporating a radio-coupled flight director, during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.

The unit is part of the Avionic Certificate IV (Aircraft Maintenance Stream) training pathway.

The unit is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation safety Authority (CASA).

Where a CASA licensing outcome is sought this unit forms part of the CASA requirement for the granting of the chosen maintenance certification licence under Civil Aviation Safety Regulation (CASR) Part 66, in accordance with the licensing provisions in the Companion Volume Implementation Guide.

Pre-requisite Unit

Assessment requirements

Modification History

Release 2. Equivalent to MEA217 Inspect, test and troubleshoot fixed wing autopilot systems and components with amended prerequisite codes.

Performance Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:

  • applying relevant WHS practices
  • using approved maintenance documentation and aircraft publications relating to the autopilot and flight director system being maintained
  • recognition of system and component defects/external damage, correct installation, connection of plugs, terminations, attaching hardware (including cabling/harnesses) and security in:
  • flight director components and interface
  • multi-axis autopilot system components
  • applying logic processes, taking and interpreting system measurements, use test equipment and appropriate wiring diagrams and manuals, to accurately and effectively isolate malfunctions in the above systems
  • testing listed systems to isolate system malfunctions and assess post-maintenance serviceability.

It is essential that system testing procedures, cleanliness requirements and safety precautions applicable to the autopilot system being maintained are fully observed, understood and complied with. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice across a range of inspection, testing and troubleshooting applications (including the timely involvement of supervisors or other trades) is critical.

Evidence of transferability of skills and knowledge related to inspection, testing and troubleshooting is essential. This is to be demonstrated through application across an autopilot system and its components.

Knowledge Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:

  • component attachment methods
  • the basic layout (block diagram level), function and operation of:
  • flight director components and interface
  • multi-axis autopilot system components
  • integration with other avionic systems, e.g. flight management systems and navigation systems
  • flight director and autopilot system maintenance requirements and troubleshooting procedures
  • relevant WHS practices
  • basic principles/functions, relating to the listed systems and associated with:
  • basic alternating current (AC) and direct current (DC) circuit theory
  • digital fundamentals
  • analogue fundamentals
  • fixed wing flight theory
  • inner and outer loop control
  • flight control modes/channels
  • relevant maintenance manuals
  • relevant regulatory requirements and standard procedures.

Assessment Conditions

  • Competency should be assessed in the workplace or simulated workplace using tools and equipment specified in the maintenance manuals. It is also expected that applicable general and special purpose tools, and test and ground support equipment would be used where appropriate.
  • The application of testing procedures should clearly indicate knowledge of system operation, the relationship of individual components and the links with other systems (if applicable) within the limits of the aircraft/system fault finding guide before undertaking any action. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards.
  • The following conditions of assessment represent the requirements of the Regulators (ADF and CASA) and maintenance stakeholders and must be rigorously observed.
  • A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements and performance criteria of the unit of competency are being achieved under routine supervision on an autopilot system and its components. This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide (for details refer to the Companion Volume Assessment Guidelines).
  • Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).
  • Where the unit is to be used for CASA licensing purposes the Assessor must also meet the criteria specified in the CASR Part 147 Manual of Standards.
