Narrative:

I was the captain on flight #abcd on oct/thurs/02 ZZZ, us. We received aircraft X at gate in ZZZ. The aircraft arrived with airframe ice visible due to the approach into ZZZ. We followed SOP in having the aircraft de-iced. We then flew the aircraft uneventfully to ZZZ1. Upon arrival in ZZZ1 the aircraft was found to have fan blade damage to the #2 engine. We were surprised to later hear about the engine damage in light of the fact that the aircraft was properly deiced and all aircraft indications were normal. Callback conversation with reporter revealed the following information: the reporter stated the airplane landing gear, engine inlet and fan blades were deiced on the gate and after pushback was taxied to a deicing pad for the entire aircraft to be deiced. The reporter said after deicing a very slight vibration was noted from #2 engine and the engine was advanced to 70 percent per the flight operating manual to shed ice. The reporter stated on flight termination the right engine was found to have fan blade damage. The reporter said the airplane had been deiced per the standard operations procedure.
