Fazenda Amadeus Andrade Airport is a small private airstrip located near Mirante da Serra, a municipality in the state of Rondônia, Brazil. It serves the agricultural operations of the fazenda (farm) it is associated with, providing essential air access to a region where road infrastructure can be limited. The airstrip is registered with Brazil's civil aviation authority (ANAC) under the ICAO code SDI4. Like many fazenda airstrips in the Brazilian interior, it primarily supports light general aviation aircraft used for farm management, cargo transport, and personal travel rather than scheduled commercial operations.
