The National Transportation Safety Board released its preliminary findings after a 43-day investigation into the aviation incident that killed NASCAR veteran Greg Biffle, his immediate family, two pilots and one other associated individual at Statesville Regional Airport in North Carolina.
A full report will still take 12 to 18 additional months to complete. NTSB preliminary reports do not place blame but merely establishes a series of facts for the next phase of the investigation to begin working off of in the following months.
