The Nigerian Safety Investigation Bureau (NSIB) and the Sierra Leone Aircraft Accident and Incident Investigation Bureau (SL-AAIIB) have signed a memorandum of understanding (MoU) to enhance collaboration on aviation safety. The agreement was formalized at NSIB headquarters in Abuja and witnessed by management teams from both institutions.
The partnership establishes a structured framework for cooperation, including joint investigations, exchange of expertise, access to investigative equipment, flight recorder analysis, and participation in each other’s investigations as accredited representatives. Both agencies will also engage in secondments, training programs, and sharing of safety data and technical knowledge.
Captain Alex Badeh Jr, Director General of NSIB, said the MoU reflects a shared commitment to improving safety outcomes across West Africa. “When investigators share knowledge, tools, and experience, response time improves, findings become more precise, and the focus remains on preventing future occurrences. That is what this partnership is designed to achieve,” he said. He added that the agreement reinforces compliance with International Civil Aviation Organization (ICAO) Standards and Recommended Practices (SARPs) under Annex 13 of the Chicago Convention.
A key feature of the partnership is human capacity development. Investigators from both bureaus will have opportunities to attend specialized training programs, observe live investigations, and strengthen their technical competence. Expert teams, including flight recorder and forensic specialists, will also support investigations conducted by either party, with logistical costs borne by the requesting agency.
Engr. Olubunmi Wellington, Commissioner of SL-AAIIB, described the agreement as “a strong opportunity to build more effective investigative systems through structured collaboration,” highlighting the benefits of access to advanced training and shared experience.
Both organizations reiterated that the primary goal of aircraft accident and incident investigations, as outlined in Annex 13 of the Chicago Convention, is the prevention of future occurrences rather than assigning blame or liability. The MoU also aligns with the collaborative principles of the Banjul Accord Group (BAG), strengthening aviation safety cooperation across the region.
With aviation activity increasing in West Africa, the partnership positions NSIB and SL-AAIIB to respond more effectively to accidents and serious incidents, conduct thorough investigations, and implement safety recommendations that contribute to safer skies.
