recognise system and component defects, external damage, correct/incorrect installation, connection of plugs, terminations, attachment hardware (including cabling or harnesses) and security in the above systems and system components

perform functional testing by applying logic processes, taking and interpreting electrical measurements, using test equipment and appropriate wiring diagrams and manuals to isolate malfunctions in the above systems 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:

system testing procedures and paralleling of generator output

the basic layout (block diagram level), function and operation of the following:

DC multi-generator and alternator or rectifier generator regulation and distribution systems and components

electrical propeller control systems, such as feathering and synchronising systems and system components

dual battery systems and associated mounting equipment, including related anti-vibration aids

fire warning and extinguishing systems and system components, including regulatory requirements relating to halogen, e.g. bromochlorodifluoromethane (BCF)) fire extinguishers

combustion heating systems and system components

equipment cooling and ventilation systems and system components

fuel storage and distribution systems and system components

master and central warning systems and system components

maintenance requirements and troubleshooting procedures for the above electrical systems

work health and safety (WHS) practices for aircraft electrical systems and components

maintenance manuals for aircraft electrical systems 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 maintaining twin-engine aircraft electrical systems 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 maintaining twin-engine aircraft electrical systems and components

tools and equipment specified in maintenance documentation

general-purpose tools and test equipment found in most routine.

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.
