ExploreAbout this exam
Subject 2 - Aircraft Engineering Knowledge is one of the theory examinations that sits inside the Civil Aviation Authority of New Zealand's aircraft maintenance engineer (AME) licensing system, which is administered under the Part 66 licence framework. It is aimed at engineers who already hold practical maintenance experience, or are building it, and who need to demonstrate the broad engineering knowledge that underpins certification work on aircraft and their systems. The knowledge area is deliberately wide: aircraft structures, aerodynamics and flight controls; airframe systems such as hydraulics, pneumatics, fuel, ice and rain protection and cabin environment; powerplant covering reciprocating and turbine engines plus propellers; electrical and electronic systems, instruments and avionics fundamentals; materials, hardware, fasteners and corrosion control; and maintenance practices, ground handling and airworthiness awareness. Because the paper spans so many systems, candidates who only revise the aircraft type they work on tend to struggle; the successful approach is to work systematically through the published syllabus, rebuild the underlying physics of each system, and then test yourself on fault-finding logic rather than memorised component names. Useful preparation includes the CAA's Part 66 AME licence syllabus page, the relevant Civil Aviation Rules, and your organisation's maintenance documentation. Note that published examination parameters - question count, sitting time, pass mark, fees and retake rules - could not be confirmed from the CAA pages retrieved, so check aviation.govt.nz before you book.

What you'll study
About CAA NZ AME Subject 2: Aircraft Engineering Knowledge preparation
What does Subject 2 actually cover?
It is the general engineering knowledge paper. Expect structures, aerodynamics and flight controls, airframe systems, reciprocating and turbine powerplants with propellers, electrical and electronic systems with instruments and avionics fundamentals, materials and corrosion control, and maintenance practices with airworthiness awareness. Check the current CAA syllabus for the authoritative breakdown.
How many questions are there, and how long do I get?
We could not confirm these from the CAA pages retrieved - the licence and examination pages returned errors at the time of checking. Treat any figure you see on a third-party site with suspicion and confirm the number of questions, sitting time and pass mark directly on aviation.govt.nz before booking.
Where is the official syllabus?
The CAA site navigation lists Engineering > Maintenance engineer licensing, which includes a 'Part 66 AME licence syllabuses' page. That page, not a training provider's summary, is the document to build your study plan from. Note that older bookmarked AME URLs on aviation.govt.nz may no longer resolve.
Is it multiple choice?
The exam is understood to be delivered as a multiple-choice theory paper, but we could not verify the format from the source pages retrieved. Confirm the current format, and whether any written or oral component applies, with the CAA or your examining organisation before you commit to a revision strategy.
Can I retake it if I fail, and how soon?
Retake rules, waiting periods and any limits on the number of attempts were not confirmed from the retrieved source. Ask the CAA licensing team directly. In the meantime, assume a resit is possible but budget for it - plan your first attempt as though it is the only one, so a failure costs you time rather than your whole schedule.
How hard is Subject 2 compared with the type-specific papers?
It is broad rather than deep. The difficulty comes from breadth: you must be comfortable with turbine and reciprocating engines, hydraulics, electrics and structures in the same sitting. Engineers strong on one system often lose marks on the others. Difficulty also depends on how recently you studied the underlying theory.
What study order works best?
Start with structures, aerodynamics and flight controls, because they explain the loads and failures you meet in every later system. Then work through airframe systems and powerplant together - hydraulics, fuel and pneumatics overlap heavily with engine knowledge. Finish with electrics, materials and maintenance practice, and revise by explaining each system aloud.
What are the most common failure modes?
Three recur: memorising component names without understanding system flow, revising only the aircraft you work on, and ignoring materials, hardware and corrosion because they feel basic. Another is reading questions too quickly - in a knowledge paper, one word such as 'primary' or 'not' changes the correct answer entirely.
Does holding a foreign AME licence help?
The CAA site lists a 'Recognising foreign AME licences' page under maintenance engineer licensing, so recognition processes exist. Whether any of your existing qualifications count toward Subject 2, and what evidence you must supply, is a question for the CAA - do not assume equivalence, and do not pay for assessment before confirming the pathway.
