Narrative:

We were in a left bank and as we leveled the wings; we saw a light transport aircraft at our 3 o'clock position (right side of the aircraft); same altitude; approximately 250 ft away and headed directly at us. We disconnected the autopilot and immediately descended to avoid a collision. Our aircraft is not equipped with TCAS/tcad. We were in radio contact with ifp tower to advise them of our operation; to improve our safety by receiving tas (understanding that this is simply informational as the tower does not have radar; just position reports from participating pilots). At 11 miles; there is no requirement to contact the tower. While in the area; we did receive a few tas; however; this particular aircraft was not talking to the tower. Approximately 15 minutes later; an additional light transport aircraft made radio contact with ifp tower. Through the tower we were able to keep up with each other's positions. We have operated in this area numerous times and I believe that the transport aircraft operate out of an airport located about 35 miles east. No damage or injuries were sustained in the avoidance of this near midair collision.
