The last 100-hour inspection was done on March 24, 2003, at 165.0 hours since major overhaul. The airframe's total time at the last inspection was 6,292.4 hours. METEOROLOGICAL INFORMATION The nearest weather reporting facility at the time of the accident was Ashville, North Carolina. The 1841 surface weather observation was: clear, visibility 7 miles, temperature 88-degrees Fahrenheit, dew point temperature 73-degrees Fahrenheit, wind 230- degrees at 8 knots, and altimeter 30.01. WRECKAGE AND IMPACT INFORMATION The wreckage of the airplane was located in a heavily wooded area 11 nautical miles east of the Franklin, Macon County Airport, just short of an open field on a heading of 289-degrees magnetic. The on-scene examination of the airplane found it inverted at the base of a large tree. Tree branches along the crash debris line exhibited 45-degree "V" cuts. All of the fabric-covering on the fuselage was consumed by fire. The cockpit, instrument panel was consumed by fire. The wood floor, and the cameras and recording equipment were fire damaged. The flight control system from the control tube at the control column aft to the push-pull tubes and rod end bearing in the center of the fuselage were fire damaged. The control tubes and rod end bearings extending outboard to the left and right wings, ailerons, and bell cranks were consumed by the post-crash fire. The control tubes and rod end bearings extending aft to the rudder and left and right elevators were fire damaged. The upper wings remained partially attached to the airframe however; the lower wings were fire damaged and had collapsed onto the underside of the upper wings. Both the left and right main landing gear remained attached to the airframe. The welded steel tubular airframe remained intact. Examination of the engine found it partially attached to the engine mounts and firewall. The engine assembly sustained fire damage on all sides. During the post-crash examination of the engine assembly, the crankshaft would rotate when the propeller was turned by hand. Continuity was established to the accessory section. Compression and valve train action was established on all seven cylinders. Both magnetos were destroyed. The Hamilton Standard two bladed variable pitch propeller, was found at the low pitch stops. One blade exhibited slight outward bending with wood fibers in the leading edge about twelve inches from the tip. The second blade was found bent aft 90-degrees near the hub. MEDICAL AND PATHOLOGICAL INFORMATION The Chapel Hill, North Carolina State Medical Examiners Office, conducted a postmortem examination of the pilot on August 18, 2003. The Forensic Toxicology Research Section, FAA Oklahoma City, Oklahoma performed a postmortem toxicology of specimens from the pilot. Carbon Monoxide was detected in the blood. There was no Cyanide detected in the blood, nor was there ethanol detected in the urine. However, Amphetamine, a stimulant, often known as "speed," was detected in the blood 0.804 (ug/ml, ug/g), urine 26.359 (ug/ml, ug/g) and liver 4.3 (ug/ml, ug/g). Tetrahydrocannabinol (THC) (Marihuana) was detected in the blood, Tetrahydrocannabinol Carboxylic Acid (THC-COOH) (Marihuana) was detected in the blood 0.0057 (ug/mo, ug/g) and urine 0.0045 (ug/ml, ug./g), and Phenylpropanolamine an over-the-counter decongestant and weight loss product was detected in the urine but not detected in the blood. ADDITIONAL INFORMATION The airplane wreckage was released to International Loss Management, Atlanta, Georgia, representing the insurance underwriter on February 19, 2004.
