The cockpit crew contacted ATC and verified that a ual A-320 had taxied behind them on juliet taxiway. The crews of both aircraft returned to their gates. Inspections by maintenance personnel verified a ground collision between the two aircraft. N328UA sustained impact damage to the underside of the right elevator and stabilizer that ran from the trailing edge of the elevator to the leading edge of the stabilizer. The NTSB reclassified the incident as an accident after reviewing the extent of damage to N328UA.
