ExploreAbout this exam
Subject 20 Air Law is one of the knowledge examinations that an applicant for a Papua New Guinea Aircraft Maintenance Engineer Licence (AMEL) issued by the PNG Civil Aviation Safety Authority (CASA PNG) is expected to pass. It is aimed at licensed and aspiring AMEs - airframe, engine, avionics and avionics-related ratings - who must show they understand the legal framework they work inside, not just the technical side of maintenance. The syllabus spans the Civil Aviation Act and PNG's regulatory structure, the PNG Civil Aviation Rules and advisory circulars, the privileges and limitations of an AME licence, airworthiness and continuing airworthiness obligations, the ICAO Annexes that PNG applies, rules of the air and airspace, operator and flight crew responsibilities, safety management and occurrence reporting, dangerous goods and security, and enforcement and liability. Preparation should be built around the current rule parts and CASA PNG advisory material rather than memory of another country's system: PNG's rules are closely modelled on ICAO standards and on familiar Australasian practice, but the differences - who issues what, which part applies, what must be reported and to whom - are exactly what the paper tests. Work through the Act and the rule parts alongside the Annexes they implement, and practise applying them to realistic maintenance hangar scenarios rather than reciting clause numbers. Question count, time allowed, pass mark, fees and retake conditions are set by CASA PNG; confirm the current details on its official website before you book.
What you'll study
About PNG CASA AME Subject 20 Air Law preparation
Who needs to sit Subject 20 Air Law?
Applicants for a PNG AMEL, and licence holders adding a category or rating, are expected to hold the air law knowledge the subject covers. CASA PNG's licensing advisory material sets out exactly which examinations apply to your licence category, so check the current requirements for your particular application before enrolling.
What is the exam format?
It is a closed-book written examination delivered as multiple-choice questions. CASA PNG publishes the current examination format, sitting arrangements and any permitted reference material; confirm these on its website or with the licensing office rather than relying on second-hand accounts from other candidates.
How difficult is it, and what trips people up?
The technical content is not the hard part; the difficulty is precision. Candidates lose marks by assuming another country's rules apply, confusing which PNG rule part governs a task, muddling reporting channels and timeframes, or guessing at ICAO Annex content instead of knowing it. Read the question for the responsible person and the exact obligation.
How long should I allow to prepare?
Most candidates need several weeks of structured study, because the material is broad rather than deep. Build a schedule around the ten topic areas, give extra time to the Act and rule structure, and finish with practice questions under timed, closed-book conditions so you can judge your own readiness honestly.
What study order works best?
Start with the Civil Aviation Act and how CASA PNG is structured, then the rule parts and advisory circulars, since everything else hangs off them. Move to licensing privileges, airworthiness and continuing airworthiness, then the ICAO Annexes. Finish with rules of the air, operations, safety reporting, dangerous goods, security and enforcement.
Can I retake the examination if I fail?
Retake arrangements, waiting periods and any fees are set by CASA PNG and can change. The official body publishes the current figures and conditions, so check its website or ask the licensing office directly before you plan a second attempt; do not assume another authority's retake policy applies.
How much does it cost and how long is the result valid?
Examination fees, result validity and the period within which you must complete remaining licence requirements are administrative matters determined by CASA PNG. These details are not fixed by the syllabus, so confirm the current fees and validity period with CASA PNG before booking or budgeting.
Do I need to memorise ICAO Annex numbers?
Knowing which Annex covers which subject helps, but the exam tests application, not trivia. Focus on how PNG implements the standards - what the rule requires, who is responsible, what records must be kept and what must be reported - because that is how the questions are framed.
Where do I find the authoritative source material?
The Civil Aviation Act, the PNG Civil Aviation Rules and CASA PNG advisory circulars are published by CASA PNG, and the ICAO Annexes are available from ICAO. Use the current versions, since amendments change the answers. Avoid relying on undated summaries or material written for another jurisdiction's licensing system.
