GRAPEVINE, Texas - An American Airlines official says an initial examination of a Brazil-bound jet that made an emergency landing at Dallas-Fort Worth airport found no evidence that an engine or its landing gear caught fire.

Airline spokesman Tim Smith said Monday that an indicator light suggested the Boeing 777's right engine caught fire but investigators don't believe it did.

The flight bound for Sao Paolo, Brazil, returned to Dallas-Fort Worth Sunday evening because of engine trouble. Smith says investigators are trying to determine the cause.

The Federal Aviation Administration had reported that Flight 963's engine and landing gear caught fire. FAA spokesman Roland Herwig previously told the Dallas Morning News the plane landed safely on a runway around 8 p.m. CDT (0100 GMT) after dumping its fuel in midair.

Smith says passengers may have mistaken the vapor trail left by fuel being dumped for smoke. He says several tires blew during the landing but that the gear didn't catch fire.
