What happened
While operating as the second aircraft in sequence behind traffic on a right base for runway 36R, the pilot was engaged in communication with local control. During the approach, the local controller inquired if visibility was hazy; the pilot responded that it was not hazy but noted the conditions were during twilight.
As the aircraft appeared to line up with runway 27, the local controller queried the pilot's intentions. The pilot stated an intention to turn downwind for runway 36R, but was instructed by the controller to turn right and enter a right base for runway 36R. When asked if the runway was in sight, the pilot replied, "roger."
A witness observed the aircraft flying at a low airspeed approximately 200 feet above ground level with wings level. The aircraft then began a bank to the left, followed by a bank to the right. Subsequently, the nose of the aircraft dropped, and it entered a left turn before descending out of sight. The airplane impacted the ground in a nose-down attitude, which triggered a fire that consumed the cockpit and cabin area.
The investigation
A post-accident examination of the aircraft revealed no structural or mechanical anomalies.
