July 20 (Reuters) - The Federal Aviation Administration

(FAA) said on Saturday it is investigating a Southwest Airlines ( LUV )

flight that was diverted after it flew at a very low

altitude over Tampa Bay, Florida.

The July 14 flight by a Southwest Boeing 737 MAX that had

departed from Columbus, Ohio, was approximately 3 miles (5

km)from the Tampa airport when it dropped to as low as about 175

feet (53 meters), according to Flightradar24 data.

This was the latest in a series of significant safety

incidents involving Southwest ( LUV ) flights, including a Southwest ( LUV ) 737

flight in April that came within about 400 feet (122 meters) of

the ocean off Hawaii and a June 25 flight that departed from a

closed runway in Portland, Maine.
