Two planes, a Peoria-bound American Eagle jetliner with 43 passengers and a smaller corporate jet, nearly collided at O’Hare International Airport, authorities said Wednesday.

The American Eagle Flight to Peoria was leaving runway 32L, while the jet was landing on runway 9R, the National Transportation Safety Board said.

The monitor for the local air traffic noticed the paths of the planes were converging and communicated to the local controller to tell the Learjet to go around, and the American Eagle to stay low as it continued its takeoff.

Federal officials accused an air traffic controller of negligence, for clearing the American Eagle for takeoff without noticing that the Learjet was approaching.

“The controller . . . neglected to see if another aircraft was arriving,” said Elizabeth Isham Cory, an FAA spokeswoman, as quoted by The Chicago Tribune.

American Airlines spokeswoman Andrea Huguely said the airline is cooperating with the NTSB, who is currently investigating the near airborne collision, and the captain filed a company report on the incident.

The board said the Learjet passed 325 feet above and slightly behind the departing the American Eagle jet. The minimum vertical separation required between airliners is 1,000 feet.

This was the 13^th incident classified as a near collision at O’Hare since 1992, according to the NTSB incident database.

Federal officials of the airport announced new procedures, which require more coordination between the tower and the Chicago O'Hare Terminal Radar Approach Control in Elgin.
