A Baltimore-bound Southwest Airlines flight from Long Island MacArthur Airport was forced to make an emergency landing in Newark on Friday, the second unscheduled stop for the carrier in two days.

Flight 3348 took off from MacArthur at 5:54 a.m., minutes before its planned 6 a.m. departure, and was scheduled to reach Baltimore-Washington International Airport about 7:10 a.m., according the airline’s website.

But the aircraft was diverted to Newark Liberty International Airport, landing at 6:43 a.m., because there was an indication in the cockpit of performance issues with one of plane’s engines, the airline said.

After the plane was taken out of service for maintenance, its five crew members and 131 passengers were put on another aircraft, the airline said.

On Thursday, Southwest Flight 1570 made an emergency landing at MacArthur nine minutes after taking off from the airport at 7:40 a.m., bound for Fort Lauderdale, Florida, after a member of the airport’s ground crew thought the plane was leaking fuel, officials said.

After the Boeing 737 returned to MacArthur, mechanics determined there had been no fuel leak, and that there was nothing mechanically wrong with the plane, acting airport Commissioner Rob Schneider said Thursday.
