An Airbus A321 of American Airlines experienced what a pilot called an “un-commanded” roll and struck runway equipment during takeoff on 10 April at New York's John F Kennedy Airport.
The aircraft departed from the airport at 20:40 local time, headed 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. The US Federal Aviation Administration is investigating, it says. “The pilot reported that the Airbus A321 may have collided with an object during departure earlier in the evening,” the FAA said “After the aircraft landed, workers discovered damage to the left wing, possibly caused by striking a runway sign and airport light.”
