Untsurientsa Airstrip (ICAO: SEUQ) is a small general aviation facility located near Untsuri Entsa in the Morona Santiago province of Ecuador. It serves as a vital access point for indigenous Shuar communities in the remote Amazonian jungle, where ground transportation is extremely limited or nonexistent. The airstrip primarily supports light aircraft operations, missionary aviation, and humanitarian supply flights rather than scheduled commercial services. Organizations such as the Mission Aviation Fellowship (MAF) have historically operated in this region to connect isolated communities with medical, educational, and logistical support.
