Nigeria does not presently have the capabilities or demand to issue its own original type certificate and will therefore not be the State of Design or State of Manufacture. Part 5 of the Regulations presents regulatory requirements for the continuing airworthiness of aircraft expected to operate in Nigeria consistent with the standards and recommended practices (SARPs) in ICAO Annex 8, Amendment 109; ICAO Annex 16, Volume I, Amendment 13; ICAO Annex 16, Volume II, Amendment 10; ICAO Annex 16, Volume III, Amendment 1 and ICAO Doc 9760, Airworthiness Manual, Fourth Edition (2020). Part 5 is designed to address the complex situation faced by most countries today respecting the airworthiness of aircraft operating within the country and in international aviation. In most such cases, there are aircraft registered in Nigeria that were designed and manufactured in another Contracting State.
