Narrative:The Bouraq Viscount was operating on a flight from Banjarmasin to Jakarta. At 06:04 the crew issued a Mayday call, stating shuddering of the airplane. Air traffic control vectored a Fokker F-28 to intercept the plane. At 06:28 the F-28 crew noticed problems with the right elevator and stated that the plane was falling to the left. After separation of the right elevator the Viscount crew lost control. It impacted the ground inverted, about 25° nose down relative to the ground and with its port wing low.
