CAA NZ AME Electrical study guide
CAA NZ AME Electrical · Work through your exam, one topic at a time.
The CAA NZ Aircraft Maintenance Engineer Licence (Electrical), often called the NZ Part 66 AME Licence - Electrical, is a New Zealand civil aviation maintenance certification administered by the Civil Aviation Authority of New Zealand (CAA). It is aimed at engineers who inspect, maintain, and certify electrical work on aircraft, and it sits within the CAA's engineering licensing framework alongside maintenance engineer licensing, Part 66 AME licence syllabuses, recognition of foreign AME licences, and type ratings for AMEL holders. The CAA NZ AME Electrical study guide has 6 sections and about 2,296 words.
01Electrical Fundamentals
This domain tests the DC and AC theory an AME uses to diagnose aircraft circuits: Ohm's and Kirchhoff's laws, series and parallel networks, magnetism, inductance and capacitance, AC impedance, power, transformers, and rectifiers. Expect numerical questions and questions on what a meter should read in an isolated or live circuit.
370 words, about 2 min02Electrical Systems and Components
This domain tests the hardware between the bus and the load: relays and contactors, switches, circuit breakers and fuses, motors and actuators, solenoids, batteries, transformer-rectifier units (TRUs), inverters, and avionics power supplies. Questions often ask you to select a component rating, explain a control circuit, or identify why a protection device operated.
389 words, about 2 min03Aircraft Electrical Power Generation and Distribution
This domain covers how aircraft generate, regulate, and distribute electrical power: DC generators and alternators, AC generators, constant-speed drives (CSDs), integrated drive generators (IDGs), variable-frequency (VF) generators, transformer-rectifier units, batteries, external and ground power, APU generators, bus ties, and essential or emergency buses. The exam tests system architecture, protection, and load-sharing logic.
366 words, about 2 min04Aircraft Wiring, Bonding and Testing
This domain tests the physical installation: wire selection and sizing, routing and support, connectors and terminations, bonding and grounding, insulation and continuity testing, and documentation of test results. The exam expects practical judgement about airworthiness and EWIS (electrical wiring interconnection system) care.
375 words, about 2 min05Aviation Regulations
This domain tests the New Zealand Civil Aviation Rules that govern maintenance and certification. Know the roles of Part 43 (general maintenance), Part 66 (aircraft maintenance personnel licensing), Part 145 (aviation maintenance organisations), Part 12 (accident and incident reporting), and Part 21 (certification).
399 words, about 2 min06Maintenance Documentation and Human Factors
This domain tests how maintenance is planned, recorded, and protected from human error. Documentation includes maintenance manuals, illustrated parts catalogues (IPCs), structural repair manuals, service bulletins, airworthiness directives, work cards, logbooks, defect reports, and maintenance releases.
