Narrative:

3 hours after we had left the aircraft I received a phone call stating that severe symmetrical inboard flap damage had been discovered on the aircraft that we had brought in from ord. The so had done a thorough preflight in ord. No such condition existed to our knowledge at the time of our departure. An uneventful and professional flight ensued culminating in a normal ILS approach to runway 4R in boston with a soft landing. No abnormalities or sounds were noted by any member of the flight deck, cabin crew or passenger. In my opinion the damage to the flaps had to have been caused after the crew had left the aircraft in boston. The way in which the flaps were damaged also strongly suggested that this was the case. Knowing what I knew at the time of flight I would not have done anything differently.
