NTSB Narrative Summary Released at Completion of Accident
An ATR-42 sustained no damage during a near midair collision with a Boeing B-747 after takeoff from runway 22L at the O'Hare International Airport (ORD), Chicago, Illinois. The B-747 had been cleared for takeoff from runway 14R by the south local controller. The ATR-42 was subsequently cleared for takeoff on runway 22L by the third local control position (3LC). When the ATR-42 was rotating, the pilots observed the B-747 that was to their right, and airborne. The ATR-42 leveled off at 100 feet above ground level (agl) and the B-747 flew over the top of the ATR-42 with about 400 feet of vertical separation. Once the B-747 had passed, the ATR-42 resumed the climb and continued en route to it destination. The flightcrew of the B-747 did not observe the ATR-42; nor did they receive an alert from the tower. The B-747 continued en route to its destination. The incident was classified by the air traffic control facility as an operational error. Following the incident, the facility developed new coordination measures between the air traffic controllers in the tower.
