A preliminary report by the Indonesian NTSC says a DHC-6 Twin Otter that crashed on the island of South Sulawesi was flying VFR in clouds when it impacted a mountain.

On October 2, 2015, a DHC-6 Twin Otter, registered PK-BRM was being operated by Aviastar Mandiri as a scheduled passenger flight with flight number MV7503. The aircraft departed from Masamba/Andi Jemma Airport to Makassar-Sultan Hasanuddin International Airport on the island of South Sulawesi in Indonesia.
The pilot-in-command acted as Pilot Flying while the second-in-command acted as pilot monitoring.
According to the flight plan clearance issued by Andi Jemma Airport Air Traffic Information Service (ATIS) the pilot intended to fly VFR with altitude of 8000 feet and fly a direct route from Masamba to Makassar.
The aircraft departed from Masamba at 06:25 UTC (14:25 LT) and estimated time of arrival Makassar at 07:39 UTC.
A partial cloud formation was present at about 60 nautical miles from Masamba on the direct track to Makassar around Mount Bajaja and Mount Latimojong.
At 06:36 UTC, the pilot informed the Ujung Pandang Information officer that the aircraft had reached 8,000 feet. One minute later the pilots discussed to fly direct to Barru from their current position. Barru is a town located at about 45 Nm north of Makassar. Both pilots agreed to fly direct and the second-in-command (SIC) explained the experience of flying direct on the flight before. A few seconds later the SIC suggested to delay the direct flight for a while. At 06:50 UTC, the pilot told the SIC that he wanted to climb and the CVR stopped recording. The aircraft impacted treetops and crashed on the top of a mountain at an elevation of 7734 feet.

All ten on board were killed.
