Narrative:

After being cleared for takeoff on runway 24R at lax, experienced an overheat warning (area J) on a widebody transport. Both overheat loops indicated an overheat, the area was isolated pneumatically. The aircraft was taxied back to the gate for maintenance action. The overheat condition lasted for 2 to 3 minutes after area was isolated. Note: the takeoff roll was never initiated, however since the aircraft was already on the runway and there was an aircraft on final approach, the taxi off the runway was expedited and lax tower reported it as an aborted takeoff. The aircraft on final did not have to initiate a go around. Callback conversation with reporter revealed following information. Area J is on hot section of the #2 engine. Maintenance found ruptured ducting causing the overheat. Aircraft out of service for 24 hours and the flight was cancelled. Has heard other carriers have had similar incidents on this widebody transport.
