Narrative:

During takeoff roll; the rear hatch of the aircraft opened and blew off the aircraft. I heard a loud noise at that time; but was unaware as to the source of the noise. I immediately aborted takeoff; and notified the tower of my intentions. I then noticed the rear hatch was no longer on the plane; and notified the tower that there was FOD on the runway. I exited the active runway (18L) at first chance and taxied back to the ramp. The plane was put in the hangar along with the hatch that was retrieved. The aircraft never left the ground. A pilot (me) and one passenger were on board. No one was injured; and there was no apparent structural damage to the aircraft.
