ORLANDO, Fla. — A Southwest Boeing 737 Max 8 being moved to a storage facility made an emergency landing at Orlando International Airport on Tuesday afternoon after experiencing engine trouble.

Flight 8701 had no passengers but two crew members aboard. No one was hurt. The plane landed just after 3 p.m. ET.

The jet was a Boeing 737 Max 8, which has been grounded internationally and across the U.S. after two crashes in the past six months killed hundreds. Crash investigators have focused on a flight-control system that's designed to automatically tilt stabilizers to prevent an aerodynamic stall.

The plane that made the emergency landing was headed to Southern California Logistics Airport in Victorville, California, for short-term storage during the fleet grounding, Southwest said. It will now be moved to Southwest's maintenance facility in Orlando for a review.

Southwest has 34 Boeing 737 Max 8s, according to the Federal Aviation Administration.

Airport spokeswoman Carolyn Fennell said the plane experienced engine trouble when it took off.

One of three runways at the airport was shut down while crews ensured there was no debris on it. Airport officials said the incident did not impact any operations.

The emergency landing comes less than a month after the airline sued its mechanics union, saying it was unnecessarily grounding planes because of maintenance issues. Southwest said an "abnormal increase" in maintenance write-ups preceded the lawsuit. The mechanics union and Southwest, which has been in a long-running labor dispute, announced they'd reached a tentative contract agreement last weekend, the Associated Press reported.
