LOS ANGELES (AP) — A Federal Aviation Administration spokesman says an American Airlines flight from Los Angeles to the Washington, D.C., area returned to Los Angeles because of a problem with the Boeing 737’s air-speed indicator.

FAA spokesman Ian Gregor said the crew of American Flight 74 declared an emergency, reversed course and landed around 1 a.m. Monday. The flight had departed Los Angeles International Airport around 11 p.m. Sunday, bound for Dulles International Airport.

American Airlines spokesman Casey Norton said after returning to LAX, the flight’s 149 passengers boarded a different airplane that departed at 2:15 a.m.

Norton said the Fort Worth, Texas-based airline is now servicing the plane for a maintenance issue.

The FAA says it will work with American Airlines to identify the problem and determine why it occurred.
