What happened
On the morning of the accident, an aircraft departed from Jakarta Airport at 10:09 local time. The scheduled route included stops in Bandung and Yogyakarta before reaching the final destination of Surabaya. During the initial stage of the flight, the crew maintained an altitude of 3,500 feet.
At 10:43 local time, the flight crew was granted clearance to ascend to 9,500 feet and were instructed to establish communication with Bandung Tower. Shortly after this ascent began, while the aircraft was cruising at approximately 5,400 feet, it collided with the western slope of Mt Burrangrang. Search efforts located the wreckage four days after the impact. The accident resulted in 21 fatalities, with no survivors among the occupants.
Findings
Investigations into the crash determined that the incident was driven by the pilot's decision to navigate over mountainous terrain despite having uncertain positioning. This maneuver was performed under weather conditions characterized by severely restricted visibility.
