Incident Overview
An aircraft operating a flight from Palembang to Jakarta experienced a right engine failure while cruising at an altitude of 9,500 feet. The crew was unable to maintain the assigned altitude, and despite jettisoning luggage and cargo, the aircraft continued to descend. The situation culminated in a forced ditching in Banten Bay, a few kilometers offshore.
Rescue and Casualties
Seven individuals were rescued from the accident. Nine others, including both pilots, were killed.
Probable Cause
According to the official investigation, the aircraft's takeoff weight at departure from Palembang was 18,192 lb, which exceeded the maximum takeoff weight of 16,160 lb. The weight of two ground fire extinguishers and a ground power unit (GPU) carried as cargo were probably underestimated.
