Fazenda Três Perobas Airport is a small private airstrip located near Santa Luzia D'Oeste in the state of Rondônia, Brazil. It carries the ICAO designator SJNK and has no assigned IATA code, reflecting its status as a non-commercial facility. The airport primarily serves the agricultural operations of the surrounding fazenda (farm), providing light aircraft access to a remote region where road infrastructure can be limited. Such private airstrips are common across Brazil's vast interior, supporting rural landowners, cargo, and occasional emergency medical services. Detailed operational data, including its founding date, runway specifications, and current status, are not widely documented in public aviation databases.
