Incident
An aircraft operating a flight from Ujung Pandang (Makassar) to Lombok Airport began its descent when the crew encountered poor weather conditions with heavy rain. Air traffic control (ATC) cleared the captain to divert to Mataram-Selaparang Airport. In limited visibility, the aircraft struck the slope of Mount Rinjani, located on the northern part of the island. The aircraft was destroyed upon impact. All 19 occupants were killed.
Probable Cause
The official investigation determined the probable cause to be controlled flight into terrain after the crew continued the approach at an unsafe altitude in poor weather conditions.
