The World Bank has approved a $47 million International Development Association (IDA) credit for Nigeria under the West and Central Africa Air Transport Safety and Security project. The project aims to create a safe and secure environment for air transport in West and Central Africa. Pierre Pozzo di Borgo, the project leader, said "by joining the West and Central Africa Air Transport Safety and Security Program, Nigeria is reaffirming its commitments to grant its Civil Aviation Authority with the necessary administrative and financial autonomy to fulfill its regulatory and oversight role in a rapidly expanding sector of its economy." The first phase of this program was approved by the World Bank's Board in April 2006 for activities in Burkina Faso, Cameroon, Guinea and Mali. At the request of the Nigerian Government, the World Bank initiated this second phase, which will help Nigeria address serious lapses in aviation security and safety following three fatal crashes of passenger airliners in 2005 and 2006. The West and Central Africa Air Transport Safety and Security program aims to improve Nigeria Civil Aviation Authority's (NCAA) compliance with International Civil Aviation Organization's (ICAO) safety and security standards as well as enhance Nigeria's main international airports' compliance with ICAO's security standards. The Federal Airport Authority of Nigeria, the Nigerian Airspace Management Agency, the Nigerian Civil Aviation Authority and the Nigerian College of Aviation Technology are the four aviation agencies will benefit from the project financing. The project activities will include a study of each aviation agency, aircraft and aircrew recertification, erection of airport perimeter fences and installation of wind shear detection systems for Lagos, Port Harcourt and Kano airports.
