Champion 8KCAB N83DH accident near Groton, South Dakota

Probable cause

The pilot’s loss of airplane control during a low-altitude aerobatic maneuver.

NTSB analysis

According to a witness, after takeoff, the pilot accelerated the airplane down the runway in ground effect before pitching the nose up to an estimated 45° angle. The airplane then rolled right and inverted and exited the roll maneuver in a nose-low attitude before impacting the ground. One witness estimated that the roll was initiated between 75 and 100 ft above ground level. Two witnesses reported that the maneuver appeared intentional due to the rapid roll rate. A family member stated that the pilot routinely performed low-level aerobatics in the accident airplane.

Examination of the airplane confirmed continuity to all flight control surfaces and no engine or airframe anomalies were found that would have precluded normal operation. It is likely that the pilot intentionally attempted the aerobatic maneuver, lost control, and was unable to recover given the altitude available.
