Chau Airstrip (ICAO: SEAU) is a small general aviation facility located in the Morona Santiago province of Ecuador, a region characterized by dense Amazon rainforest and rugged terrain. The airstrip primarily serves as a lifeline for remote indigenous communities and small settlements that lack road connectivity to larger urban centers. The facility supports light aircraft operations, including missionary aviation, medical evacuation flights, and cargo transport to isolated villages in the region. Organizations such as Mission Aviation Fellowship (MAF) and similar groups have historically operated in this area to serve dispersed jungle communities. Morona Santiago province is home to the Shuar and other indigenous peoples, and airstrips like Chau play a critical role in providing access to healthcare, supplies, and emergency services in an otherwise largely inaccessible region.
