(CNN) A Boeing 737 Max 8 aircraft from the fleet that was grounded after two deadly crashes made an emergency landing in Florida on Tuesday.

No passengers were aboard Southwest Airlines Flight 8701, which was being ferried from Orlando International Airport to Victorville, California, for short-term storage during the grounding, the airline said.

Just before 3 p.m. Tuesday, the two pilots aboard the flight reported "a performance issue with one of the engines shortly after takeoff," the airline said.

"The crew followed protocol and safely landed back at the airport."

The global fleet of 737 Max jets was grounded indefinitely on March 13 after two fatal crashes involving the aircraft in March and October.
