Natuna Besar Island

While on a maritime patrol flight from Natuna Ranai to Tanjung Pinang, the crew was approaching a Singapore warship when an engine failed. Unable to maintain a safe altitude, the pilot attempted to ditch the aircraft when it crashed in the sea off Mapur Island. Two passengers and the captain were killed while 11 other occupants were rescued.

The aircraft took off from Hong Kong-Kai Tak Airport bound for Jakarta at 0425 hours Greenwich Mean Time carrying 8 crew members and 11 passengers. The flight was uneventful until approximately five hours after take-off when a muffled explosion was heard in the aircraft while cruising at an altitude of 18,000 feet over the sea. Smoke started entering the cabin through the cold air ducts almost immediately and a localized fire was detected soon after on the starboard wing behind the number three engine nacelle. A rapid descent was commenced for ditching the aircraft and distress signals broadcast. In spite of fire fighting action, during which No. 3 engine was feathered, the fire spread very rapidly and caused hydraulic failure followed by electrical failure. During the final stages of the descent, executed under extremely difficult circumstances, dense smoke entered the cockpit reducing the visibility to almost nil. The aircraft impacted the water with the starboard wing tip, and the nose submerged almost instantaneously. Only three crew members survived the accident. The aircraft was destroyed. All passengers were Chinese and European journalists flying to Jakarta to take part to the Asia-Afro Bandung Conference.
