SAN JOSE (CBS SF) — An engine malfunctioned as an American Airlines flight to Dallas was on the taxiway at Mineta San Jose International Airport early Friday, forcing the 737 to return to the gate, officials said.

Flight 1318 was preparing for its scheduled 6:05 a.m. take-off and “was taxiing the runway when the engine shutdown,” said Mineta San Jose International spokeswoman Vicki Day.
