Narrative:

I was informed that I had been a crew member on an aircraft that had flown without the correct maintenance information, maintenance release and flight time logs. I had no knowledge of this occurrence until now. The previous night, 2 company aircraft flew into the outstation where they would stay until morning. These aircraft had very similar call signs. Maintenance was performed overnight and the maintenance personnel accidentally swapped the maintenance log between the 2 aircraft. Neither myself nor my captain, nor the other crew, caught this mistake. Therefore, although we checked the log for the proper documentation, it was not the correct information for our aircraft. This was a problem that started with maintenance, but should have stopped with us. We should have been more thorough in the review of our documents and not assumed that the correct log was on the aircraft.
