Airworthiness and Aircraft Registration/Import Requirements
Registration and airworthiness are separate
Registration identifies the aircraft; the certificate of airworthiness (C of A) certifies its airworthiness. Nigerian-registered aircraft carry the nationality mark 5N- followed by the registration letters. Registration requires an eligible owner or operator and acceptable evidence of title. The C of A requires type acceptance, inspection and continuing maintenance.
Import sequence
- Pre-import application and type acceptance with the NCAA.
- Export C of A from the state of export, plus logbooks, modification records and AD/SB status.
- Customs clearance and NCAA inspection.
- Registration and issue of a Nigerian C of A or validation.
- Radio station licence, insurance and maintenance release before flight.
Worked example
A used Cessna arrives with a foreign C of A and foreign marks. Can it be flown locally on that basis? No. It must be registered as 5N- and issued a Nigerian C of A, or hold a valid validation, before flight. The export C of A supports the import but does not replace the Nigerian certificate. Reasoning: airworthiness certification is state-specific; the importing state must satisfy itself that the aircraft meets its requirements.
Traps that cost marks
- Flying after import on foreign marks or a foreign C of A.
- Treating the C of A as permanent; it has validity and depends on continuing maintenance.
- Missing the radio station licence or insurance.
- Fitting unapproved modifications without NCAA acceptance.
- Assuming an export C of A is automatically convertible into a Nigerian C of A.
