What happened
A private pilot, who was not instrument-rated, was performing a VFR cross-country flight while under the guidance of air traffic control. During the cruise phase, the pilot began maneuvering to avoid convective weather near the intended destination. Although the controller provided warnings regarding moderate to extreme precipitation along the flight path, the pilot indicated that they were monitoring the weather via NEXRAD and intended to bypass the cells.
Approximately three minutes after confirming they had bypassed the weather, the pilot requested permission to begin a descent toward the destination. The controller permitted the descent at the pilot's discretion. Radar tracking showed the aircraft performing a descending right turn, but contact was lost at an altitude of 2,900 feet mean sea level. No witnesses observed the event, though search teams noted thunderstorms and heavy rain were present in the vicinity at the time of the accident.
Findings
Investigation of the wreckage indicated that the debris field was consistent with an in-flight breakup. Structural analysis of the airframe identified overload failures within the wings and the empennage. The propeller showed signs of rotation during the impact, and no structural anomalies were present on the airframe prior to the accident. There was no evidence suggesting the pilot was incapacitated or impaired.
Evidence suggests the pilot likely entered instrument meteorological conditions as the aircraft descended through the weather. The transition from visual to instrument conditions, combined with the convective environment, likely led to spatial disorientation. This disorientation likely caused the pilot to lose control of the aircraft during the final maneuvers.
