A near collision between two commercial jets at LaGuardia Airport in New York City earlier this month is under investigation, the Federal Aviation Administration confirmed Monday.

An investigation has been opened by the Federal Aviation Administration and the National Transportation Safety Board after a United Airlines plane and a Republic Airways jet nearly collided on the runway on May 6.

Federal officials are investigating why two planes got dangerously close on a runway at New York's LaGuardia Airport earlier this month despite the airport being equipped with an advanced surface radar system that's designed to help prevent such close calls.
