NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
According to a witness, who was in a field approximately 1 mile north of the accident site, the airplane was performing aerobatic maneuvers in the area when the airplane flew straight up into the air, and then "fell over into a flat spin." At this point, the witness estimated that the airplane at an approximate altitude of 5,000 feet above the ground. The witness heard the engine "revving up" as the airplane descended behind a tree line. He then heard the airplane impact the ground and the engine stop running. The 1,040-hour pilot, who was occupying the rear seat of the tandem seating experimental bi-plane, purchased the airplane during the first week of July 2004. Post-accident calculations revealed that the airplane was over maximum gross weight and the center of gravity (CG) was aft of the rearward limit. According to page 3-8 of the Christen Eagle II Airplane Flight Manual, "Any particular Christen Eagle II aircraft will recover from any spin type using standard recovery techniques ONLY IF THE AIRCRAFT IS PROPERLY BALANCED. The CG of the aircraft must be within design limits to ensure safe spin recovery. Any aircraft can be dangerously loaded (CG beyond design limits) making spin recovery extremely difficult or impossible. Weight and balance considerations must be taken seriously and pilots must be absolutely certain that the flight CG of their aircraft is within design limits."
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot's intentional spin, which was unrecoverable due to exceeded aircraft weight and balance limitations as a result of improper preflight planning/preparation. Full narrative available
