Procedure; Human Factors
I was made aware of aluminum speed tape that was applied to the First Officer side ADC ports that I flew 4 legs in. As to where or when the tape was applied I am unable to answer. The First Officer taking the plane from us on a crew change found the speed tape covering both First Officer's ADC ports in a vertically applied position. The plane flew just fine for us with no EICAS messages or irregularities in altitude; airspeed or vertical speed control on either side. I am unsure if my First Officer missed the tape on his walk around or if someone with foul intent applied this tape. A good quality preflight would have caught this; if it was in fact applied before we took the plane.
I was made aware of the circumstance at the end of my trip. From the Chief Pilot's office and Captain I flew the trip who contacted the chief pilot. I am unaware of when or how or who attached the tape to the side of the airplane. No inflight abnormalities or cues where given that it affected our flight in any way. I am unsure if it was maliciously placed there or due to a maintenance person.
An EMB-145 crew was notified that tape was discovered over the First Officer side ADC port by the receiving crew during a crew change they had flown numerous legs that morning.
