List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. | Inspect instrument systems and components | 1.1 | Isolation tags are checked and aircraft configured for safe system inspection and operation in accordance with the applicable maintenance manual |
| | 1.2 | Instrument system components are visually or physically checked for external signs of defects in accordance with applicable maintenance manual while observing all relevant work health and safety (WHS) requirements |
| | 1.3 | Defects are correctly identified and recorded in accordance with standard enterprise procedures |
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 instrument system being maintained
recognition of system and component defects/external damage, correct installation, connection of plugs, terminations, and attaching hardware (including cabling/harnesses) and security in:
pitot/static systems and associated instruments and systems
flight instruments
GPWS and FDR
stall warning, angle of attack and stall avoidance systems
navigation systems (compasses and AHRS)
pressure measurement, position indicators, engine/auxiliary system indication systems, including fuel quantity and flow.
It is essential that inspection procedures, cleanliness requirements and safety precautions applicable to the instrument system being maintained are fully observed, understood and complied with. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice (including the timely involvement of supervisors or other trades) is critical.
Evidence of transferability of skills and knowledge related to inspection is essential. This is to be demonstrated through application across a range of aircraft instrument systems and components listed in the Assessment Conditions.
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
connection of hardware
instrument system maintenance requirements

flight instruments, including:
ASIs
VSIs
air data systems and components
machmeters
altimeters, including servo and encoding altimeters
turn and slip indicators
AHs
DGs
angle of attack and stall warning/avoidance systems
pitot/static systems
navigation systems:
direct reading compasses
gyro compasses
AHRS
GPWS
turbine engine instruments, including:
temperature and pressure, including thermocouples, sensors and transmitters
speed, including mechanical and electric tachometers
thrust, including fan, propeller and jet
torque
fuel flow
vibration
auxiliary transmitter/indicator measuring systems, including:
hydraulic pressure and temperature
pneumatic pressure
transmission oil pressure and temperature
fuel remaining/used
fuel quantity indication
component position (e.g. doors, flaps, speed brakes and landing gear)
FDR systems
relevant WHS practices
instrument system maintenance requirements
relevant maintenance manuals
relevant regulatory requirements and standard procedures.
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 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 a system and at least (1) one major system component/line replacement unit (LRU) from each of the following groups:
flight instruments, including pitot/static systems, ASIs, VSIs, altimeters, altitude alerting and reporting, turn and bank and slip/turn coordinators, DGs and AHs (air and electrically driven)
machmeters, air data systems, angle of attack, stall warning and avoidance systems
FDRs
engine indication systems
magnetic compasses and AHRS
miscellaneous instrument systems, including pressure measurement, fuel quantity, fuel flow, position indication, voltage and frequency, current and power
GPWS.
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.
Individuals being assessed who have already attained MEA213 Inspect, test and troubleshoot advanced aircraft instrument systems and components, will have covered a significant proportion of the Performance Criteria for Element 1 and will have covered many of the Range of Conditions variables. The Log of Industrial Experience and Achievement records relating to MEA213 Inspect, test and troubleshoot advanced aircraft instrument systems and components, may be accepted as also meeting the evidence requirements for this unit in the applicable areas.
The relationship between MEA213 Inspect, test and troubleshoot advanced aircraft instrument systems and components, and MEA212 Inspect, test and troubleshoot basic aircraft instrument systems and components may also be taken into account where MEA212 Inspect, test and troubleshoot basic aircraft instrument systems and components has been attained, but not MEA213 Inspect, test and troubleshoot advanced aircraft instrument systems and components. Advice in MEA212 Inspect, test and troubleshoot basic aircraft instrument systems and components regarding the coverage of MEA275 Maintain basic light aircraft instrument systems and components, may also be taken into consideration where applicable.
