The National Agency for the Safety of Flight () is the Italian aviation accident investigation agency. The ANSV is headquartered in Rome. The italian Prime Minister oversees the agency.
It was established by legislative decree No. 66, 25 February 1999. Prior to the establishment of the ANSV, there would be two different investigations for each aviation accident or incident, one by the airport director and another more formal and technical investigation by an ad hoc committee appointed by the Ministry of Infrastructure and Transport. After its establishment, only one investigation has been made.
