Unit of competency
Modification History
Release 1. Application changed. Elements and Performance Criteria changed. Foundation Skills made explicit. Assessment Requirements clarified. Supersedes and is equivalent to MEA216 Inspect, test and troubleshoot instrument landing systems and components.
Application
This unit describes the skills and knowledge required to apply hand skills and use system and component knowledge, maintenance publications, and test equipment to inspect, test and troubleshoot instrument landing systems (ILS) and components of fixed and rotary wing aircraft during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.
The unit is used in workplaces that operate under the airworthiness regulatory systems of the Civil Aviation Safety Authority (CASA) and the Defence Aviation Safety Authority (DASA).
Any other relevant legislation, industry standards and codes of practice within Australia must be applied.
Pre-requisite Unit
MEA206 Remove and install aircraft basic radio communication and navigation system components
MEA246 Fabricate and/or repair aircraft electrical hardware or parts
MEA293 Remove and install aircraft electronic system components
Competency Field
Aviation maintenance
Elements and Performance Criteria
|
Elements
Elements describe the essential outcomes.
|
Performance Criteria
Performance criteria describe the performance needed to demonstrate achievement of the element.
|
|
1. Inspect ILS and components
|
1.1 Identify specific inspection requirements using maintenance documentation and modification status, including relevant system defect reports
1.2 Check isolation tags and configure aircraft for safe system inspection and operation in accordance with maintenance manual
1.3 Visually or physically check ILS components for external signs of defects in accordance with maintenance manual while observing all relevant work health and safety (WHS) requirements
1.4 Identify and report defects in accordance with standard enterprise procedures
|
|
2. Test or adjust ILS and components
|
2.1 Prepare aircraft and system for application of power or system operation in accordance with maintenance manual
2.2 Perform functional testing of ILS for evidence of serviceability or malfunction in accordance with maintenance manual
2.3 Perform required calibration or adjustments to system in accordance with maintenance manual
|
|
3. Troubleshoot ILS
|
3.1 Use available information from maintenance documentation, inspection and test results to assist in fault determination of identified issues
3.2 Troubleshoot issues to line replacement level using maintenance manual fault diagnosis guides and logic processes
3.3 Obtain required specialist or supervisory advice to assist with the troubleshooting process
3.4 Locate ILS faults and identify and record causes of faults in required maintenance documentation in accordance with standard enterprise procedures
3.5 Determine requirements for rectification of faults
|
Foundation Skills
This section describes those language, literacy, numeracy and employment skills that are essential to performance but not explicit in the performance criteria.
- Reading skills to interpret maintenance manuals, inspection procedures and specifications (allowable limits).
- Writing skills to record and report on defects and faults and their causes.
- Numeracy skills to interpret and communicate technical information and take and interpret system measurements.
Other foundation skills essential to performance are explicit in the performance criteria of this unit.

Assessment requirements
Modification History
Release 1. Application changed. Elements and Performance Criteria changed. Foundation Skills made explicit. Assessment Requirements clarified. Supersedes and is equivalent to MEA216 Inspect, test and troubleshoot instrument landing systems and components.
Performance Evidence
There must be evidence the candidate has completed all the tasks outlined in the elements and performance criteria of this unit, and demonstrated the ability to:
- perform inspection, testing and troubleshooting on instrument landing systems (ILS) and components during scheduled or unscheduled maintenance on an ILS and at least one major system component or line replaceable unit (LRU)
- recognise system and component defects, external damage, correct or incorrect installation, attachment hardware (including cabling or harnesses or transmission lines) and security in the ILS
- perform functional testing by applying logic processes and taking and interpreting system measurements to accurately and effectively isolate malfunctions and faults in the ILS being worked on, and perform system testing to isolate system faults and assess post-maintenance serviceability
- apply testing procedures, cleanliness requirements and safety precautions at all times, and as relevant to the system/s being maintained.
Knowledge Evidence
There must be evidence the candidate has knowledge of:
- component attachment methods
- the basic layout (block diagram level), function and operation of the system
- integration with other avionic systems
- the location and operation of ground:
- marker beacons
- localiser transmitter
- glideslope transmitter
- ILS maintenance requirements and troubleshooting procedures
- work health and safety (WHS) practices for instrument landing systems and components
- basic principles and functions relating to the system and associated with:
- electromagnetic radiation and propagation
- basic alternating current (AC) and direct current (DC) circuit theory
- digital fundamentals
- analogue fundamentals
- transmitter and receiver principles
- antenna characteristics
- transmission line characteristics
- maintenance manuals for the inspection, testing and troubleshooting of ILS and components
- relevant regulatory requirements and standard procedures.
Assessment Conditions
The following conditions of assessment represent the requirements of the regulators (DASA) and (CASA) and maintenance stakeholders and must be rigorously observed.
Skills must have been demonstrated under routine supervision in the workplace or in a simulated environment that reflects workplace conditions and contingencies encountered in inspecting, testing and troubleshooting ILS and components. The following conditions must be met for this unit:
- use of suitable facilities, equipment and resources, including:
- workplace procedures, manufacturing specifications, codes, standards, manuals, and reference materials relevant to inspecting, testing and troubleshooting ILS and components
- general and special-purpose tools and items of ground support and test equipment required for inspecting, testing and troubleshooting ILS and components.
Evidence of tasks demonstrating competency must be recorded in a log of industrial experience and achievement.
Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors.
