Fazenda Santa Luzia Airport is a small private airstrip located in the municipality of São Félix do Xingu, in the state of Pará, Brazil. It serves the agricultural and ranching operations of the fazenda (farm) after which it is named, providing essential air access in a remote region where road infrastructure is limited. The airport carries the ICAO designator SDE1 and has no assigned IATA code, reflecting its status as a private, non-commercial facility. São Félix do Xingu is one of the largest municipalities in Brazil by area, situated in the southern Amazon basin, making small airstrips like this one critical for connectivity. Facilities are minimal, consistent with a private farm airstrip, and the airport does not handle scheduled commercial passenger traffic. It primarily supports light general aviation aircraft used for local transport, agricultural oversight, and emergency access.
