Analysis

The owner/plt-in-command (PIC) took off on a local flt with another occupant in the front seat. The front seat occupant was a commercial, single-eng, multi-eng plt with an instructor rating, but he had no previous experience in A75 acft. While in flt, the PIC allowed the front seat plt to take control of the acft. As the front seat plt entered a turn at low alt near the arpt, the PIC advanced the throttle to maintain airspeed in the turn. At that time, the front seat plt thought the PIC had taken control of the acft; he thought they were returning back to the arpt. The acft continued turning & entered a descent. The PIC thought the front seat plt was still controlling the acft & was going to make a low pass. Since the front seat plt was an instructor with over 1000 hrs of flt time, the PIC did not question the maneuver. Subsequently, the acft impacted the ground while still in a steep descent.
