Incident Overview
On March 25, 2008, at 0822 Zulu, an Air Atlanta Icelandic Boeing 747-300, registration TF-ARS, operating under a wet lease to Saudi Arabian Airlines, encountered a fire on the No. 3 engine pylon during the landing rollout at Dhaka International Airport. The aircraft had just touched down and was slowing when air traffic control advised the flightcrew of smoke and flames emanating from the aircraft.
Crew Actions
The flightcrew taxied the aircraft clear of the runway and subsequently received an engine fire warning for the No. 3 engine. Following standard procedures, the crew discharged both engine fire bottles, but the fire did not extinguish. After the second bottle was used, the tower informed the crew that the smoke and flames were increasing. The crew then ordered an evacuation of the aircraft.
Investigation Findings
Investigators determined that the fuel leak originated from the coupling connection of the No. 3 fuel tank to the main fuel line that connects the tank to the pylon. Upon removal of the fuel line, it was discovered that one of the two retaining rings was missing. Maintenance had been performed on the No. 3 tank fuel line connection to replace the o-ring six months prior to the incident.

The Bangladesh Civil Aviation Authority delegated the investigation to the Aircraft Accident Investigation Board of Iceland, placing the probe under the jurisdiction of the Government of Iceland. Further information regarding the event can be obtained from the Aircraft Accident Investigation Board in Reykjavik, Iceland.
