An Indonesian twin-turboprop plane carrying 54 passengers and crew reportedly crashed in the country's mountainous and densely wooded Papua province, according to Transportation Ministry.
There was no distress call from the Trigana Air Service ATR42-300, and authorities suspended a search that was to resume Monday morning.
Villagers reported seeing a plane crash into a mountain and rescuer were heading to the location to look for wreckage and possible survivors, officials said. Local media said that the 49 passenger and five crew members aboard were all Indonesian.
The plane was en route from Papua's provincial capital, Jayapura, to the city of Oksibil in the central part of the island (which also includes the independent state of Papua New Guinea).
Michael Sullivan, reporting for NPR from Thailand, says: "The plane went missing as it was on its approach to land amid heavy rain, strong winds and heavy fog, according to Indonesian officials. Papua is among the most remote provinces in Indonesia — which has a checkered air safety record in recent years."
An AirAsia flight crashed in December after taking off from Surabaya, Indonesia, killing all 162 aboard.
The Associated Press quotes Susanto, who like many Indonesians goes by one name, as saying a plane was sent to look for the missing airliner, but that darkness and bad weather had caused the search to be pit on hold until morning. Later Transport Ministry officials confirmed the crash following reports from villagers of wreckage in Papua's Oktabe District.
Susanto said later that residents of Okbape village in Papua's Bintang district told authorities they saw a plane flying low before crashing into a mountain.
