Personnel licensing and AME licensing requirements
Domain overview
This domain tests NCAA personnel licensing under Nig. CARs Part 2 and ICAO Annex 1, with emphasis on the aircraft maintenance engineer (AME) licence: eligibility, ratings, privileges, validity, and conversion of foreign licences.
Core rules and concepts
- An AME licence is issued by the NCAA and is not a general 'mechanic' permit; it carries category ratings (for example airframe, engine, avionics) and type ratings for specific aircraft.
- Applicants must meet minimum age, education, language proficiency, medical fitness, approved training, practical experience, and examination requirements.
- Privileges are limited to the categories and types endorsed. Certification of maintenance, inspection, repair, or modification must be within those privileges and any AMO authorisation.
- Licences have validity periods and renewal conditions; recent experience and records must be maintained.
- Foreign licences may be validated or converted under NCAA procedures, but recognition is not automatic; the applicant must satisfy Nigerian requirements and any limitations.
Worked example
An AME with an airframe rating signs off an avionics repair. Reasoning: the signature certifies work outside the endorsed category. Even if the AME is employed by an approved maintenance organisation, the personal licence privilege does not extend to avionics unless that category is endorsed, or the task is authorised under the AMO's procedures with appropriately qualified staff. The correct action is to refer the task to an avionics-rated AME.
Traps
- Assuming a licence with one type rating covers all aircraft of the same manufacturer.
- Treating a foreign licence as automatically valid in Nigeria.
- Confusing AMO approval with personal licensing; both are needed where regulations require.
- Forgetting that medical fitness and recent experience remain conditions of the licence.
