Narrative:

The aircraft just came out of maintenance so we checked all the paperwork and it checked ok! I did the weight and balance and assisted with the preflight and we had trouble closing the door but we fixed it. We made the flight but was unable to engage the autoplt. After a couple days we found out the autoplt board was not installed in the aircraft which includes the yaw dampener which is required for flight.
