American Airlines said it is going over its policies and procedures with the Federal Aviation Administration, in light of sending the wrong commercial aircraft on a flight from Los Angeles to Hawaii.

Airlines spokesman Casey Norton said it has already corrected a software program.

“We’re going over our policy and procedures with the FAA to see if there is anything else we need to do,” Norton said Sunday afternoon.

American Airlines Flight 31 was halfway from Los Angeles to Hawaii on Aug. 31, when airline officials realized they had sent the wrong plane and decided to continue to Honolulu.

The airplane was returned to Los Angeles in a ferry capacity without passengers. Norton said passengers scheduled to be on the return flight were accommodated on other airlines and American Airlines flights.

Planes that fly long routes with no suitable landing areas on the way, such as the Los Angeles-Honolulu route, require certification called ETOPS (Extended-range Twin-engine Operational Performnce Standards).

The plane was not ETOPS-certified, although its fuel tanks, engine and range of flight are the same.

“There were a couple of minor differences with the aircraft,” he said.
