An Indonesian domestic passenger aircraft with 54 people on board has gone missing over eastern Papua, the National Search and Rescue Agency (BASARNAS) stated Sunday, after losing contact with air traffic control. 

The flight, operated by Trigana Air Service and a short 50-minute jaunt over land from Jayapura’s Sentani airport to the capital of Papua province, Oksibil, was carrying 44 adults, 5 infants and children, and 5 crew members. 

BASARNAS chief Bambang Soelystyo confirmed to Reuters that contact with the plane, a ATR 42-300 twin turboprop, had been lost at about 3 p.m. local time. 

According to Transportation Minister Julius Barata, the plane was not equipped with ADS-B tracking technology.

In December 2014, AirAsia Flight QZ8501 crashed over the Java Sea en route from Surabaya to Singapore, killing 162 people.
