Two American Airlines jets have landing gear trouble

Two separate incidents involving American Airlines jets with landing gear problems were resolved safely Friday afternoon.

American Airlines Flight 1613 from Chicago to San Francisco turned around after pilots realized the landing gear hadn't fully retracted. The jetliner returned to O'Hare International Airport and landed without any trouble at 2:20 p.m., authorities said.

A total of 136 passengers were on board, American Airlines said.

Another jetliner, American Airlines Flight 862, from West Palm Beach headed to Chicago also had an unexpected diversion when a cockpit alarm system indicated the gear was still deployed.

The airplane burned off fuel and flew by the air traffic control tower at Miami International Airport so controllers could check the gear was down before pilots made a safe descent at 2:45 p.m.

There were 131 travelers on Flight 862.

Federal Aviation Administration officials said the two incidents were under investigation. Fire and rescue crews were on hand at both airports in case of any emergencies.

American Airlines spokeswoman Mary Frances Fagan said the passengers were being shifted to other flights.

"Our pilots did exactly what they were trained to do," Fagan said. "We treat these incidents very conservatively."
