A search for the plane was suspended and will resume Monday morning.
The Trigana Air Service plane was flying from Papua's provincial capital, Jayapura, to the Papua city of Oksibil when it lost contact with Oksibil's airport, said Transportation Ministry spokesman Julius Barata. There was no indication that the pilot had made a distress call, he said.
The ATR42-300 twin turboprop plane was carrying 49 passengers and five crew members on the scheduled 42-minute journey, he said. Five children, including three infants, were among the passengers.
