Usarumpia Airstrip is a small rural airstrip located in Papua New Guinea, identified by the ICAO code AYUX. It serves the local community of Usarumpia, providing vital air access to a region where road infrastructure is limited or nonexistent. Like many remote airstrips in Papua New Guinea, Usarumpia plays a critical role in connecting isolated communities to essential services including medical care, supplies, and government services. Small mission and charter aircraft are the primary users of such facilities. The airstrip lacks the infrastructure of larger commercial airports and is likely a basic grass or gravel strip suited to light aircraft operations typical of bush flying in the Pacific island nation.
