[1] The aircraft departed Surabaya-Juanda Airport at 11:35 pm inbound for Balikpapan.
While in cruising altitude, the airplane disappeared from radar screens and presumably crashed into the Java Sea.
Search and rescue operations were conducted but eventually suspended after a few days, as no trace of the aircraft nor the 26 occupants was found.
The crew was unable to send any distress call prior to the accident.
Due to a lack of evidence, it was not possible to determine the exact cause of the accident.
