Available data from Nigeria Bureau of Statistics shows a decline in the Nigeria Aviation sub-sector (Transport Sector) real growth rate in 2017Q1. Compared to the preceding quarter, the sub-sector declined significantly by 9.6 percent, due to decline in the number of passengers and movement of aircrafts this may be connected to the closure of the Abuja airport for infrastructural development during the period. To ensure a near-optimal performance of the aviation sector, the government should also make efforts to improve aviation safety and security, establish a national carrier, and improve aircraft maintenance to world class standards.
