Read the full NTSB narrative
While on initial descent into O'Hare International Airport, the flight crew of United 1517 received a Traffic Advisory (T/A) followed by a Resolution Advisory (R/A) from the Traffic Alert and Collision Avoidance System (TCAS). The flight crew reported their altitude as being about 11,500' when the T/A was received. The first radar hit on the target airplane was at 11,200'. The Captain executed an abrupt pull-up in order to avoid colliding with the other airplane. Two flight attendants were injured during the evasive maneuver. The pilot of the other airplane reported that when passing through 10,000' he noticed his Mode C transponder was not selected; at that time, he changed the selector position. Investigation of the event revealed the closest separation between the two airplanes was .1nm horizontally and 50' vertically.
