American A321 suffers ‘un-commanded’ roll during takeoff incident

The aircraft took off from the airport at about 20:40 local time, bound for Los Angeles as American flight 300. When we departed… strong roll to the left… as we climbed out,” the pilot told air traffic controllers shortly after takeoff, according to an audio recording from LiveATC.net. “We were banking… Uncontrolled bank 45° to the left. Turbulence from another aircraft the pilot adds. “I don’t think so. There’s a good crosswind, but we had an un-commanded roll to the left as we rotated. The pilot also tells controllers that the aircraft was at that point “flying great”, and he requests clearance to return to JFK, where the A321 landed without incident at 21:09.
