All 12 people on board a Trigana Air Service de Havilland Canada DHC-6 Twin Otter were killed when the aircraft crashed into a mountain in Indonesia's West Papua province on 17 November.

The Twin Otter (PK-YPY) crashed "6-7min" before it was due to land at Ilaga on a charter flight from Mulia, says an airline source. The accident happened around 08:30.

The source says there were nine passengers - officials from one of Indonesia's regencies - and three crew. Although weather conditions were reportedly good, the source says mountain areas can nevertheless be covered by cloud.

Flight's ACAS database records the 29-year-old aircraft as one of three Twin Otters in Trigana's fleet.

Meanwhile, a 39-year-old Boeing 727-100 freighter operated by Colombia's Aerosucre was destroyed in an 18 November crash, killing all five people on board. According to local reports, the 727 (HK-3667X) crashed at around 21:00 on approach to Leticia airport, Colombia. It was reportedly on a flight from Bogotà. Initial reports say the aircraft struck a radio tower on approach. Weather at the time was reportedly reasonable with visibility of 10km (5.4nm) and wind calm, but with fog patches.
