Indonesian Search and Rescue teams have been dispatched to find a Trigana aircraft that reportedly crashed in Papua province.
The plane was making the short flight from Jayapura to Oksibil when it lost contact with air traffic control last night, shortly after the pilot asked to descend.
It had 54 people on board.
The area where the turboprop plane is understood to have crashed has been located in the Oktabe district in the remote east of Papua, near the Papua New Guinea border
However a government official has incicated that the search and rescue teams will not be able to reach the wreckage quickly, as the terrain is mountainous and densely forested, with few roads.
