It is essential that cleanliness requirements and safety precautions applicable to the system being maintained are fully observed, understood and complied with, as well as work practices associated with electrostatic sensitive devices. Evidence of transferability of skills and knowledge related to removal and installation is essential. This is to be demonstrated by application across a range of aircraft major electrical system components encompassing electrical with mechanical interface and installations that require alignment and/or adjustment (mechanical or electrical).



(b) 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 basic knowledge of:

• Component attachment methods.

• Connection of hardware and plugs.

• Relevant WHS practices.

• The use of approved maintenance documentation and aircraft publications relating. to AC and DC electrical systems.

• Properties of permanent magnets.

• Precautions for the care and storage of permanent magnets.

• Bonding of aircraft components and lightning protection.

• General construction, operating characteristics and applications for aircraft:.

• GGenerators.

• Fartheerlternators.

• AC and DC motors.

• Transformer rectifier units

• Rotary and static inverters.

• Batteries.

• Linear and rotary actuators.

• Relevant maintenance manuals.

• Relevant regulatory requirements and standard procedures.

• Environmental protection requirements relating to Halon fire extinguishers (e.g. Bromochlorodifluoromethane (BCF)).

18. รายละเอียดกระบวนการและวิธีการประเมิน (Assessment Description and Procedure)

• The assessment are based on combination of paper exams, interviewing, and practical demonstrations depending on the assessors’ judgement.

• Competency should be assessed in the work environment or simulated work environment, using tools and equipment specified in maintenance manuals. It is also expected that general-purpose tools, test and ground support equipment found in most routine maintenance situations would be used where appropriate.

• An understanding of the attachment methods, connection of hardware, and the need for adjustment or rigging and system operation as they relate to the work must be demonstrated before undertaking any action. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards.

• 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 at least one (1) component from:

• DC and AC power generation and distribution system components, including generators and related multi-sourced DC power generation, starter generators alternators and regulation, and control and distribution system components.

• Transformer rectifier units and/or inverters.

• Batteries and related bus tie or interlock system components and battery temperature monitoring systems.

• Motors and actuators.

• Components of gas turbine and/or piston engine ignition and starting systems (may be omitted where not applicable to the enterprise).

• External/internal lights.

• And on three (3) components that are applicable to the enterprise from:

• Electrical components of specific electrical systems, such as air cycle air conditioning, combustion heaters, equipment cooling, anti-icing and de-icing, landing gear, anti-skid, flight control, master and central warning, fuel storage and distribution, fire warning and extinguishing and engine/propeller control.

• This shall be established via 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).
