NCAA AME Basic Air Law cheat sheet

The Civil Aviation Act 2022 is Nigeria's principal aviation statute; it repealed the Civil Aviation Act 2006 and establishes the Nigerian Civil Aviation Authority (NCAA) as a body corporate headed by a Director-General.

NCAA's statutory functions include personnel licensing, aircraft registration and certification, approval of maintenance organisations, issue of air operator certificates, surveillance, enforcement and making Nig. CARs.

The Minister of Aviation and Aerospace Development provides policy direction; technical safety decisions and certificate actions are taken by NCAA and its Director-General, not by the Minister.

Separate agencies have distinct roles: NAMA provides air navigation services, FAAN operates federal airports, NiMet provides meteorology, and NSIB investigates accidents and serious incidents.

NCAA operates a fund made up of fees and charges for licences, certificates, inspections and permits, together with government subvention; it does not depend solely on annual appropriation.

Authorised NCAA inspectors have powers of entry to aircraft, hangars, maintenance facilities and operator premises, and may require production of records; obstruction of an inspector is an offence.

Nig. CARs are subsidiary legislation; if a regulation conflicts with the Act, the Act prevails, and where a regulation is silent the applicable ICAO Annex standard is the reference.

NCAA enforcement tools include warning letters, administrative fines, variation, suspension and revocation of certificates, and referral for prosecution; the procedures and notice requirements in Nig. CARs must be followed.

The Convention on International Civil Aviation was signed at Chicago on 7 December 1944 and entered into force on 4 April 1947; Nigeria is a contracting State.

Article 1 recognises that every State has complete and exclusive sovereignty over the airspace above its territory, including territorial waters.

Article 6 requires special permission or authorisation for scheduled international air services; non-scheduled flights are dealt with under Article 5.

Article 29 lists documents to be carried on aircraft, including the certificate of registration, certificate of airworthiness, crew licences, journey logbook, passenger manifest and radio station licence.

Article 31 provides for the certificate of airworthiness issued by the State of registry; Article 33 requires other States to recognise it and personnel licences where the issuing State's standards equal or exceed ICAO minima.

Article 37 obliges each State to collaborate in securing uniformity of regulations and to adopt international standards; Article 38 requires notification to ICAO of any difference between national practice and a standard.

The 19 ICAO Annexes contain Standards and Recommended Practices: Standards are mandatory subject to filed differences, while Recommended Practices are desirable but not binding.

Annex 1 (Personnel Licensing), Annex 6 (Operation of Aircraft), Annex 8 (Airworthiness), Annex 13 (Aircraft Accident and Incident Investigation) and Annex 19 (Safety Management) are most relevant to maintenance engineers.

The first two freedoms, overflight and technical stop, are exchanged under the International Air Services Transit Agreement; commercial freedoms require bilateral air services agreements.

AME licensing in Nigeria is governed by Nig. CARs Part 2 (Personnel Licensing), which implements ICAO Annex 1.

The NCAA Aircraft Maintenance Engineer Licence is issued with category ratings: A for airframe, P for powerplant and E for avionics/electronics.

A type rating endorsement is required before an AME may certify on a specific aircraft type; the endorsement is entered on the licence after assessment.

Basic eligibility includes the minimum age, completion of an approved training course, supervised practical experience, passing NCAA examinations and a recommendation from the approved training organisation.

Practical experience must be gained under an approved maintenance organisation or an appropriately rated AME and documented in a personal logbook.

Privileges are limited to the categories and type ratings held; the AME may certify maintenance, inspection, repair and modification but remains accountable for each certification.

Recent experience and continuation training are required to keep privileges current; a lapse may require refresher training or re-assessment before certification resumes.

NCAA may validate or convert a foreign AME licence after verification with the issuing authority and assessment of the holder against Nigerian requirements and regulations.

Fraud, incompetence, violation of regulations or failure to maintain recent experience are grounds for suspension, revocation or variation of an AME licence.

Nig. CARs Part 5 governs airworthiness: registration, certificate of airworthiness, continuing airworthiness, modifications, repairs and maintenance records.

A standard certificate of airworthiness is issued after inspection confirms conformity with the approved type design and is normally valid for 12 months; renewal requires continued compliance and inspection.

Aircraft must be maintained in accordance with an approved maintenance programme based on manufacturer recommendations, type design and operating experience.

Airworthiness Directives are mandatory; no aircraft may fly until all applicable ADs are complied with and the action is recorded in the maintenance records.

Nig. CARs Part 6 governs Approved Maintenance Organisations, covering approval, facilities, personnel, procedures, quality systems and records.

The Certificate of Release to Service certifies that maintenance was completed satisfactorily and the aircraft is airworthy for the intended flight.

The Minimum Equipment List allows flight with specified equipment inoperative, subject to defined conditions, limitations and rectification intervals; defects outside the MEL must be rectified before flight.

Major repairs and modifications require approved design data, such as a supplemental type certificate or NCAA approval, before installation and return to service.

Maintenance records, aircraft logbooks, work cards and AD compliance records must be retained and made available to NCAA as the evidence trail for airworthiness.

Nigeria's State Safety Programme implements ICAO Annex 19; operators and approved maintenance organisations maintain a Safety Management System appropriate to the size and complexity of their operations.

ICAO's Universal Safety Oversight Audit Programme assesses Nigeria's effective implementation of ICAO standards across the eight critical elements, including primary legislation, regulations and surveillance.

Occurrence reporting is mandatory: accidents and serious incidents must be notified without delay to NCAA and NSIB, while other specified occurrences are reported under the mandatory occurrence reporting scheme.

ICAO Annex 13 defines accident and serious incident; the State of Occurrence investigates, and the States of Registry, Operator, Design and Manufacture may participate.

NSIB conducts independent investigations to determine causes and issue safety recommendations; it does not assign blame or liability.

Just culture protections encourage reporting of errors and hazards; wilful violations and gross negligence remain subject to enforcement action.

NCAA enforcement tools include warning letters, administrative fines, suspension, revocation and variation of certificates, and prosecution.

Surveillance is risk-based and includes ramp inspections, audits, spot checks and follow-up on findings; unresolved Level 1 findings can lead to certificate action.
