Mui Airstrip (ICAO: AYYU) is a small, unregistered airstrip located in the Mui area of Papua New Guinea. It serves as a critical access point for a remote community that would otherwise be largely isolated from the rest of the country, given the challenging terrain and lack of road infrastructure in the region. Like many rural airstrips in Papua New Guinea, Mui Airstrip primarily supports light aircraft operations, missionary aviation, and occasional government or humanitarian flights. It plays a vital role in connecting local residents to essential services, medical care, and supplies.
