About this exam

The NCAA Aircraft Maintenance Engineer (AME) Licence Knowledge Test - Airframe is one of the knowledge examinations administered by the Nigeria Civil Aviation Authority as part of the aircraft maintenance engineer licensing process. It is aimed at candidates who already hold appropriate practical maintenance experience or training and now need to demonstrate the theoretical knowledge required for an AME licence with an airframe rating. The syllabus and detailed requirements for all NCAA knowledge tests are published in Advisory Circular NCAA-AC-PEL 018, available under Personnel Licensing Advisory Circulars on the NCAA website; candidates should treat that advisory circular, together with the Nig. CARs, as the controlling statement of scope. The airframe paper covers airframe structures and airframe systems - typical content includes structural materials and assembly methods, sheet metal and composite repair, flight controls, hydraulic, pneumatic, fuel, ice and rain protection, landing gear, and cabin environmental systems. Preparation should be built around the NCAA-AC-PEL 018 syllabus, the current Nig. CARs, and the manufacturer's maintenance documentation for the types you work on. Work through the syllabus line by line, confirm each topic against approved maintenance manuals and regulations, and practise explaining systems in your own words rather than memorising isolated facts.

What you'll study

Common questions

About NCAA AME Airframe preparation

What format is the NCAA AME knowledge test?

NCAA knowledge tests are multiple-choice examinations taken at the Authority. Applications to sit them can be submitted at NCAA Headquarters in Abuja and at the Regional Offices in Lagos, Kaduna and Enugu. Confirm the current sitting arrangements, duration and item count with the NCAA Personnel Licensing office before you travel, since the public FAQ does not publish those details.

What score do I need to pass?

The passing grade for the NCAA knowledge test is 75 per cent. Because the paper is multiple choice, aim comfortably above that line in practice - a margin of ten to fifteen points on mock tests protects you against a bad set of questions on the day.

How long is my pass result valid?

Knowledge test results are valid for 24 calendar months from the date of issuance of the result. Plan the rest of your licensing process - experience sign-offs, skill assessment and licence application - so that everything is completed inside that window, otherwise you may need to sit the knowledge test again.

What happens if I fail?

Applicants who fail a knowledge test can apply to retake it after presenting evidence of having received additional instruction from an Authorised Instructor in the areas of deficiencies. This means your retake application must be tied to identified weak areas, so keep a record of which syllabus topics let you down and get documented instruction on exactly those.

Where do I find the 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 NCAA website at www.ncaa.gov.ng/documents. Download it first and build your study plan from its airframe section rather than from generic question banks, which may follow a different scope.

How difficult is the airframe paper?

It rewards system-level understanding rather than recall of isolated numbers. Candidates who have only read summaries often struggle with questions that ask why a component is designed a particular way, or how a fault in one system affects another. If you can sketch each system from memory and explain its normal and abnormal operation, you are close to ready.

In what order should I study?

Start with airframe structures - materials, stresses, sheet metal and composite repair - because system questions assume that background. Then take systems in functional groups: flight controls, hydraulic and pneumatic power, landing gear, fuel, ice and rain protection, and cabin environment. Finish with pressurisation and air conditioning, which combine several earlier topics.

What are the most common failure modes?

Three recur: confusing similar-sounding systems, such as pneumatic versus hydraulic actuation; memorising limits without understanding which component they protect; and skipping structures because it feels less interesting than systems. A fourth is ignoring the regulatory framework - questions grounded in the Nig. CARs catch candidates who studied only technical manuals.

Can I use my work experience as preparation?

Yes, and you should. Maintenance tasks expose you to real component locations, rigging and fault isolation that no textbook conveys. Pair that experience with deliberate study: after each task, read the relevant manual chapter and the syllabus topic it maps to, so your practical knowledge is organised the way exam questions are framed.
