Narrative:

On an instructional flight at livermore, ca, we landed our small aircraft on 25L. Controller informed us on landing rollout that we were cleared to land 25R. The flight in a small aircraft originated from sjc at XX00 (local) with student (private pilot, instrument rated) and instructor (reporting person, CFI/mei). After a short flight which included some airwork (slow flight, stalls, steep turns, gear down emergencys, etc.), we executed our first touch-and-go 25L at livermore. Controller instructed us to fly left traffic after the touch-and-go. Midfield downwind (left traffic 25), controller issued 'small aircraft, livermore tower, cleared to land 25L.' private pilot acknowledged 'cleared to land 25L.' on landing rollout, controller informed us we were cleared to land 25R. The controller did not pursue the issue. Both instructor and private pilot believe the landing clearance was for 25L. (Only the voice tapes could confirm this). 1) carefully listen, write down, and readback critical clearance elements. 2) watch for other traffic for signs that something is not correct maybe you and/or the other aircraft (or controller) are in the process of making a mistake. 3) pray that you discover the mistake and take corrective action before it becomes an accident.
