Samangoky Airport, designated IATA code TDV and ICAO code FMSN, is a small regional airport located near Tanandava in the Atsimo-Andrefana region of southwestern Madagascar. It serves the sparse local population and provides air access to an otherwise isolated part of the country where road infrastructure is limited. The airport operates primarily as a domestic facility, supporting light aircraft and regional turboprop services connecting the area to larger Malagasy cities. Its role is largely practical, enabling humanitarian, administrative, and occasional private travel to this remote coastal region.
