The NTSB recommendation came Monday in response to four close-call incidents in 2012 and one in 2006 in which aircraft came dangerously close to one another in cases of a "go-around," CNN reported Tuesday.
A "go-around" is when a pilot aborts a landing at the last minute and pulls up to circle the airport for another try at landing.
In each of the five close-call cases, the paths of the aircraft would not have intersected had it not been for one of them aborting a landing, CNN said.
"The NTSB is concerned that in these events, [air traffic control] was not able to ensure the safe separation of aircraft," said NTSB Chairwoman Deborah Hersman in a letter to FAA Administrator Michael Huerta.
The FAA said it would respond to the NTSB recommendations within 90 days.
