Narrative:

Aircraft was towed to the departure gate from the maintenance hangar approximately 10 minutes before scheduled departure time. It was a very cold day and we were already behind with the late arriving aircraft. It needed full catering as well as potable water; and I was assisting the flight attendants in the back flipping seats over back to their normal position. We pushed back 6 minutes late; the subsequent flight uneventful except for the ground delay before takeoff. The turn was also uneventful as we had a slight break of 2 hours between flights. While descending into the airport we had a 'fire system fail' status message and I wrote it into the discrepancy log; also informing maintenance control via ACARS. After landing speed-tape was discovered covering angle of attack vanes on the outside of the aircraft. The tape was not discovered during the [previous] walk around inspection of the aircraft. There was no abnormal indication of any kind in the cockpit during either of the 2 legs. Suggestions: despite the cold temperatures a very thorough walk around inspection of the aircraft must occur; especially when the aircraft has just left a maintenance hangar.
