NTSB Narrative Summary Released at Completion of Accident
While on an instructional cross-country flight in visual meteorological conditions, the airplane experienced an in-flight breakup during an aerobatic maneuver. Five maneuvers of interest were identified in the radar data for the accident flight. During the last maneuver the airplane's airspeed exceeded 134 knots calibrated airspeed (KCAS). According to the airplane's type certificate data sheet, the airplane's maximum maneuvering speed was 116 KCAS. Fellow flight instructors revealed that the accident flight instructor had reported performing "rolls" and/or "snap rolls" in the past while in the flight school's airplanes. In addition, one primary flight student reported that the accident flight instructor had demonstrated "rolls" and "spins" to him during flight lessons. No preimpact mechanical deficiencies with the airplane were noted, and all fracture surfaces were consistent with overload separations.
NTSB Probable Cause Narrative
The pilot's intentional performance of aerobatic maneuvers that exceeded the design limits of the airplane structure.
