Aldeia Apalai Bona Airstrip (ICAO: SDK2) is a small, unpaved airstrip located in the remote Amazon region of Pará state, Brazil, near the municipality of Almeirim. It serves the indigenous Apalai community, providing essential air access to a settlement that has no practical road connections to the outside world. The airstrip functions primarily as a lifeline for the local indigenous population, facilitating the delivery of supplies, medical assistance, and government services. Aircraft operating here are typically small, single-engine planes suited to short, unpaved runways. Given its remote and specialized nature, the airstrip sees very limited traffic and is not served by any commercial scheduled airlines. Access is generally restricted to missionary aviation organizations, government agencies, and authorized personnel.
