Agenzia Nazionale per la Sicurezza del Volo (ANSV, "National Agency for the Safety of Flight") is the Italian aircraft accident investigation agency. The ANSV is headquartered in Rome.
It was established according to legislative decree No. 66 on 25 February 1999. Prior to the establishment of the ANSV, after each aviation accident or incident, two investigations were carried out, including a perfunctory investigation by the airport director and a formal and technical investigation by an ad hoc committee appointed by the Minister of Infrastructure and Transport. Since the establishment of the ANSV, one investigation by the ANSV is carried out after an aviation accident or incident.
