ExploreAbout this exam
The NCAA AME Basic Air Law examination is a knowledge test for candidates seeking an Aircraft Maintenance Engineer licence in Nigeria. It assesses whether an applicant can apply the legal framework that governs maintenance, continuing airworthiness and regulatory compliance - not just technical hand skills. The five equally weighted areas are the Nigerian Civil Aviation Act and NCAA regulatory framework; the ICAO Chicago Convention and international air law; personnel licensing and AME licensing requirements; airworthiness and maintenance regulation under the Nig. CARs; and safety oversight, enforcement and occurrence reporting. The test is multiple choice and the pass mark is 75%. Results are valid for 24 calendar months. Applications are submitted at NCAA headquarters in Abuja and at the regional offices in Lagos, Kaduna and Enugu. The syllabus and requirements are published in Advisory Circular NCAA-AC-PEL 018, listed under Personnel Licensing Advisory Circulars on ncaa.gov.ng/documents. Prepare from primary law: Civil Aviation Act 2022, Nig. CARs 2023 (Official Gazette) and the current advisory circulars. Read each Part as a maintenance engineer would use it - approval holders, defect reporting, records, release to service - then practise applying the rule to short scenarios.

What you'll study
About NCAA AME Basic Air Law preparation
How is the AME Basic Air Law test scored?
It is multiple choice and the passing grade is 75%. The source does not publish a question count or duration, so do not plan around a fixed number of items. Aim to be comfortably above 75% in every domain, because the five areas are equally weighted and a weak domain can pull the total down.
How long do I have to use a passed result?
Knowledge Test results are valid for 24 calendar months from the date the result is issued. That is a hard planning constraint: if your licence application slips past that window, expect to sit the test again. Diarise the expiry date as soon as you receive the result.
What happens if I fail?
You can apply to retake the test after presenting evidence that you have received additional instruction from an Authorised Instructor in the areas of your deficiencies. The retake is not automatic and is not simply a repeat sitting: the evidence of remedial instruction is part of the application. Identify your weak domains before requesting the retake.
Where can I apply to take the knowledge test?
Applications can be submitted at the Authority's headquarters in Abuja and at the regional offices located in Lagos, Kaduna and Enugu. Confirm current opening hours and appointment arrangements with the office you intend to use before travelling, because the website lists several regional locations and service points.
Where is the official syllabus?
The syllabi and requirements for all knowledge tests are in Advisory Circular NCAA-AC-PEL 018, located under Personnel Licensing Advisory Circulars on the Authority website at ncaa.gov.ng/documents. Use that AC as your scope document, then map each learning objective to the Civil Aviation Act 2022, Nig. CARs 2023 or the relevant advisory circular.
What study order works best?
Start with the Civil Aviation Act 2022 and the NCAA's role, then the Chicago Convention framework, then personnel licensing and the AME licence procedure. Move to airworthiness and maintenance under the Nig. CARs, and finish with oversight, enforcement and occurrence reporting. That order builds the legal vocabulary before you meet the maintenance-specific duties.
What are common failure modes?
Candidates often memorise general ICAO principles but cannot cite the Nigerian instrument that implements them. Others revise the superseded Nig. CARs 2015 instead of the 2023 gazette edition, or skip occurrence reporting and enforcement because they seem unrelated to maintenance. Another trap is knowing a rule but not how it applies to a record, defect or release decision.
Do the five domains carry equal weight?
Yes - the published blueprint gives each of the five domains 20%. That means there is no safe domain to skip. A candidate who is strong on airworthiness but weak on the Civil Aviation Act or licensing can still fail. Build a score profile from practice questions and spend revision time on the lowest-scoring domain first.
Is the exam open book or time-limited?
The source does not state the duration or whether reference material is permitted, so treat those as unknowns and confirm with the NCAA or your Authorised Instructor. Do not assume you can carry the Act or CARs into the room. Prepare as though you must recall the instrument, the duty holder and the reporting trigger without notes.
How current is the regulatory material?
Use the Civil Aviation Act 2022 and Nig. CARs 2023 (Official Gazette). The NCAA site lists Nig. CARs 2015 as superseded, so older study notes built on the 2015 rules are a liability. Check the advisory circular list for amendments before your test date, because circulars and all-operator letters change between sittings.
