US safety investigators are reviewing a near midair collision of an American Eagle Embraer ERJ-145 and a Learjet 60 at Chicago O’Hare International Airport on 21 July.

The Embraer regional jet was departing runway 32L while the Learjet was landing on runway 9R. Once the converging paths of the two aircraft was observed by the assistant for the local aircraft controller, the Learjet was advised to go around while the controller instructed the ERJ-145 to stay low on its departure.

Analysis of radar replays show the Learjet passed 325 feet and slightly behind the departing ERJ-145.

The US National Transportation Safety Board (NTSB) says as a result of this incident, new procedures are in place for arrivals to runway 9R requiring specific coordination between approach control and the tower to determine if 9R is in use.

Neither aircraft was damaged, and NTSB says no injuries were reported.
