The Nigerian Civil Aviation Authority stated that the emergency shutdown was in order to overhaul the runway and build a fence around the facility. Such maintenance had been in planning stages for several months, but an electrical fire on 17 August 2006 made repairs immediately necessary. All domestic flights were diverted to Sam Mbakwe Airport (Owerri), Akanu Ibiam International Airport (Enugu) and Margaret Ekpo International Airport (Calabar), while international flights were diverted to Nnamdi Azikiwe International Airport (Abuja) or Murtala Mohammed International Airport (Lagos).
