Read the full NTSB narrative
The pilot stated that the flight and landing approach were uneventful. He recalled configuring the airplane for landing by extending the landing gear and flaps then began the landing flare. His next recollection was of being in the airplane at the right side of the runway surrounded by a cloud of dust. He did not have any recollection of how the airplane got there. Examination of the airplane found the landing gear had collapsed; the nose structure was deformed. While the exact cause of the pilot’s behavior change could not be determined from the available evidence, it is likely he was impaired by a medical event during landing and then possibly incapacitated for a short time. A number of possibilities could explain this event, none of which would have left any direct evidence and all of which could have caused a period of unconsciousness or amnesia. Although he was diagnosed with COVID-19 following the accident, symptoms would have been unlikely to suddenly severely impair the pilot and his memory but allow him to fully recover within a few minutes.
