Boeing 747-400

Full Narrative

On March 25, 2008 at 0822 Zulu time, an Air Atlanta Icelandic Boeing 747-300, registration number TF-ARS, wet leased to Saudi Arabian Airlines, experienced a fire on the No. 3 engine pylon during the landing rollout at the Dhaka International Airport. According to the notification report, on the landing rollout the tower advised the flightcrew of smoke and flames coming from the aircraft. The flightcrew taxied the aircraft clear of the runway and then received an engine fire warning in the No. 3 engine. The flight crew performed the engine fire procedures and discharged both fire bottles but the fire did not extinguish. After the 2nd bottle was discharged, the flightcrew was advised that the smoke and flames were increasing and ordered an evacuation.

The source of the fuel leak was determined to be from the coupling connection of the No. 3 fuel tank to the main fuel line that connects the tank to the pylon. When the fuel line was removed it was discovered that one of the two retaining rings was missing. Maintenance was performed on the No. 3 tank fuel line connection to replace the o-ring 6 months prior to the event.

The Bangladesh Civil Aviation Authority delegated the investigation to the Aircraft Accident Investigation Board of Iceland; therefore this investigation is under the jurisdiction of the government of Iceland. Further information pertaining to this accident may be obtained from:
