The East African Community Civil Aviation Safety and Security Oversight Agency (EAC CASSOA) provides a forum for the East African States (Burundi, Kenya, Rwanda, Tanzania and Uganda) and coordinates activities as an RSOO. CASSOA has steered the harmonization of civil aviation regulations and guidance material on flight safety, aerodromes and air navigation services. The Agency in Partnership with EASA has installed the SOFIA system as a working tool for certification, licensing and inspection in all EAC Partner States. The EAC aviation examination system has been procured with funding from development Partners to harmonize personnel license exams in East Africa. CASSOA also promotes sharing of aviation technical expertise within the East Africa region which has benefitted all Partner States.
