Beschrijving:
Flight AI315 to Delhi, India, suffered a No 4 engine fire some five minutes after takeoff from Bangkok, Thailand. Both extinguishing bottles were fired, but the fire warning persisted. Fuel dumping was commenced as the crew prepared to return to Bangkok's Don Muang Airport. Meanwhile the flight engineer noted an actual fire as he went down to the passenger cabin to observe.
Fuel dumping was abandoned and the flight made an immediate overweight landing on runway 03L. The fire was contained by the fire services on the ground. During the evacuation, eight passengers were injured.

Probable Cause:

The probable cause of the accident has been attributed as:
The inflight engine fire was caused by a fuel leak on the left forward side of the engine near the air to fuel convertor valve which was observed by the Aircraft Maintenance Engineer during Transit 'C' Check of the aircraft prior to take off but the leak was not conclusively identified and remained unrectified.
The injuries to the passengers were caused as they overshot the escape slide ends due to momentum and grazed the hard ground during the process of emergency evacuation. Non-adherence to the emergency evacuation procedure by some of the cabin crew members was a contributory factor".
