Narrative:Sterling Flight 296 was a charter service from Colombo (CMB), Sri Lanka to Copenhagen (CPH), Denmark. Refueling stops were planned at Bombay, Dubai, and Ankara.
After a one-hour stopover at Bombay, the flight took off for Dubai at 15:20 hours UTC. An IFR flight plan was submitted for airway R19, containing five reporting points. The en route altitude was FL310 and all reporting points were passed ahead of schedule.
At 17:25 the crew received the current Dubai weather information which showed a wind from 040 degrees at 8 knots; 10 km visibility; and 5/8 clouds at 2000 feet.
At 17:42 the flight contacted Dubai Approach and reported on the 084 radial of the Dubai (DO) VOR. The approach controller told the crew to expect descent clearance at 17:55. However, at 17:49, the crew radioed approach control, requesting an immediate descent as they were 95 NM out. Unknown to the crew, their actual position was 162 NM from Dubai.
The controller cleared the flight down to 4000 feet and reported that runway 30 and 12 were both available. The flight replied: "We will see if we can make this a straight in on 30".
At 17:56 hours the flight reported descending through FL135. The controller replied: "Recleared 'DO' 2000 feet on Dubai 1016 mb report 2000 feet or field in sight". In conditions of darkness the flight crew likely spotted the city lights of Fujayrah, Ghurayfah and Kalba during the descent, assuming these were the lights of Dubai.
Radio contact between the flight and Dubai Approach became more difficult during the descent over mountainous terrain. As a result of flying over mountainous terrain, about 80 km to the east of Dubai, flight 296 also had difficulty in tuning into the NDB and VOR frequencies.
Descent was continued until the plane struck a mountain ridge at 1600 feet.
PROBABLE CAUSE: The cause of the accident was that the aircraft descended below the minimum prescribed altitude, because the pilots thought they were closer to Dubai than they actually were, probably due to incorrect information from the outdated flight plan or because of misinterpretations of weather radar or a combination of both and that pilots when they got visual contact with the cities of Fujayrah, Ghurayfah and Kalba, believed to have confirmed their position through the perception that these were Dubai.
