Two planes approached a Florida airport, the NTSB said

A passenger plane last month was cleared by air traffic controllers to land on the same runway at a Sarasota, Florida, airport from which a second plane was also cleared to take off, officials said Thursday, detailing another in the series similar close calls at US airports this year.

According to the National Transportation Safety Board, at approximately 9:00 p.m. EST on February 16, Air Canada Rouge Flight #1633, bound for Toronto, Canada, was cleared to take off from the airport’s runway 14. However, American Airlines Flight 2172 from Charlotte, North Carolina was also cleared to land on the same runway.

The pilots of the American Airlines flight eventually aborted the landing, according to a preliminary NTSB report. The planes came within six-tenths of a mile of each other, the NTSB said.

The Air Canada flight had 188 passengers and six crew members on board, while the American Airlines flight had 172 passengers and six crew members on board, the NTSB said. There are no casualties.

The NTSB did not speculate on what caused the confusion. The agency said it has formed an air traffic control task force to investigate the incident with help from the Federal Aviation Administration and the National Air Traffic Controllers Association.

The preliminary report comes only a day later The FAA conducted emergency security summit to consider countless recent failures on the runways of the airport, the first such extraordinary summit in 14 years.

“I think I speak for all of us, and certainly for travelers, that these developments are cause for concern,” Acting FAA Administrator Billy Nolen said at the summit.

There have been at least nine such close calls this year. the latest happening March 7 at Ronald Reagan Washington National Airport in Virginia when a plane taxied across a runway from which another plane was cleared to take off.
