Boeing 737 Max makes emergency landing in Orlando
A Southwest Airlines Boeing 737 Max has made a safe emergency landing in Orlando, Florida, after experiencing an engine problem, the Federal Aviation Administration said.
The crew declared an emergency after taking off from Orlando International Airport at around 2:50pm local time, and returned to the airport safely.
No passengers were on board, and the aircraft was being ferried to Victorville, California, where Southwest is storing the planes.
The 737 Max was grounded in the US on March 13 after a deadly crash involving a Max in Ethiopia on March 10.
It was the second fatal crash involving the plane. US airlines are allowed to shuttle the planes, but cannot carry passengers.
The FAA says it is investigating but the emergency was not related to anti-stall software that is suspected as a cause of the two fatal crashes including one last year involving a plane from Indonesia.
Airport spokeswoman Carolyn Fennell says one of the airport's three runways was shut down for cleaning after the landing.
She says it is standard procedure to check a runway for debris after an emergency landing. It was not clear if any parts actually fell off the plane.
Ms Fennell says the airport's other two runways remained open, and normal operations were not affected.
Southwest did not immediately respond to email and telephone messages left by reporters.
