Aircraft Accident/Incident Report
Chicago, Illinois 60666
Saturday, December 4, 2010 21:21 CST
NTSB Narrative Summary Released at Completion of Accident
A regional jet was waiting to be marshaled into a gate. A Boeing 747 taxied behind it and the 747's right winglet contacted the regional jet's horizontal stabilizer, causing substantial damage. The first officer of the 747 thought that he had sufficient clearance to taxi by the regional jet. The first officer reported that the flight was his first out of that airport.
NTSB Probable Cause Narrative
The Boeing 747 first officer’s failure to maintain clearance from another airplane while taxiing due to his inadequate judgment of the distance between the airplanes.
