Air India flight 136 departed at 8:33 pm (local time) on Monday evening for Frankfurt, Germany, and safely returned to the airport at 10 pm after dumping fuel, said airport spokeswoman Nancy Castles.
Television footage showed sparks flying from the 747-400 aircraft, as it made its emergency landing. There were no reports of injuries.
The Federal Aviation Administration temporarily halted flights at the airport, while the aircraft was landing, but operations resumed soon afterward, Castles said.
More than 100 fire-fighters and paramedics were standing by, when the plane returned, said Los Angeles fire department spokesman Jim Wells.
"We were prepared for the worst scenario to take place," he said.
