Paa-Piu Airport is a small general aviation airstrip located in the municipality of Mucajaí in the state of Roraima, Brazil. It serves as a vital access point for remote communities in the Amazon region, including indigenous Yanomami territories, where surface transport is extremely limited or nonexistent. The airstrip operates primarily to support missionary flights, medical evacuations, government operations, and supply deliveries to isolated communities. Organizations such as FUNAI (Brazil's indigenous affairs agency) and various humanitarian groups rely on facilities like Paa-Piu to reach populations deep in the rainforest. As a small, unpaved airstrip, it lacks the infrastructure of commercial airports and is not served by scheduled airline routes. It is registered under the ICAO code SWMV and is essential for sustaining life and services in one of Brazil's most remote regions.
