A delegation of the US Federal Aviation Administration (FAA) is in Nigeria for the reassessment of Category 1 status, the West African country's aviation authority said on Sunday.

The four-man team would on Monday begin a five-day inspection of facilities in the West African country, Benedict Adeyileka, the acting director-general of Nigerian Civil Aviation Authority (NCAA) , told reporters in Lagos, Nigeria's commercial hub.

The team will carry out assessment of NCAA's compliance with the applicable sections of the International Civil Aviation Organization (ICAO) Standards contained in Annexes 1, 6 and 8, he said.

According to him, it was in line with the eight critical elements of a state safety oversight as described in the ICAO document 9734 A.

The director general told reporters that the team will use the current International Aviation Safety Assessment (IASA) checklist and ICAO guidance material during the assessment.

He listed the eight critical elements to include primary aviation legislation, specific operating regulations, state civil aviation system, safety oversight functions and technical personnel qualification and training.

Others are technical guidance and tools, incensing and certification obligations as well as surveillance obligations and resolution of safety concerns.

Adeyileka said NCAA had provided responses to the checklist and forwarded them to the FAA team leader in preparation for the visit.

He said the team would also inspect Nigeria's Arik Air and its facilities.

Nigeria attained the FAA Category 1 air safety rating from the US government under FAA's IASA program on Aug. 23, 2010.

The status deals with Nigeria's compliance with international air safety standards set by the ICAO which establishes international standards and recommended practices for aircraft operations and maintenance.
