South African Airways Flight 295 - History of The Flight

History of The Flight

South African Airways Flight 295 was a Boeing 747-244B Combi, named The Helderberg (registration ZS-SAS; serial number 22171) that was delivered to the airline in 1980. The aircraft took off on 27 November 1987 from Taipei Chiang Kai Shek International Airport, on a flight to Johannesburg via Mauritius. Dawie Uys served as the captain of the flight.

The Boeing 747-244B Combi is a variant of the aircraft that permits the mixing of passengers and airfreight on the main deck according to load factors on any given route and Class B cargo compartment regulations. Flight 295 had 140 passengers and six pallets of cargo on the main deck. The master waybills stated that 47,000 kilograms (100,000 lb) of baggage and cargo were loaded on the plane. A Taiwanese customs official performed a surprise inspection of some of the cargo; he did not find any cargo that could be characterized as suspicious.

Thirty-four minutes after departure, the flight contacted Hong Kong air traffic control to obtain clearance from waypoint ELATO to ISBAN. A position report was made over ELATO at 15:03:25, followed by waypoints SUNEK at 15:53:52, ADMARK at 16:09:54 and SUKAR at 16:34:47. The aircraft made a routine report to the South African Airways base at Jan Smuts (ZUR) at 15:55:18.

At some point during the flight, a fire developed in the cargo section on the main deck; the fire was probably not extinguished before impact. The 'smoke evacuation' checklist calls for the aircraft to be depressurised, and for two of the cabin doors to be opened. No evidence exists that the checklist was followed, or the doors opened. A crew member might have gone into the cargo hold to try to fight the fire. A charged fire extinguisher was later recovered from the wreckage on which investigators found molten metal.
