It has two runways, 36-18 and 04-22. The airport has no air traffic control tower, with no instrument approach procedures. At the time of the accident the airplane was maneuvering. WRECKAGE AND IMPACT INFORMATION Examination of the wreckage path revealed it was 350 feet in length on a 180-degree magnetic heading. Examination of the accident site revealed freshly broken tree branches at the top of a 50-foot tree at the beginning of the wreckage path. The right aileron was located at the base of the first stand of trees. The right wing tip was located approximately 50 feet from the aileron along the wreckage debris path. The left wing tip was located approximately 20 feet above the ground along the wreckage debris path in a tree. The first ground scar was 200 feet from the first freshly broken tree. The foliage in the area of the ground scar showed signs of intense heat. The engine was located 30 feet from the ground scar resting against a severely fire damaged house. The main fuselage was located in the rear of the home. Examination of the right wing revealed the right aileron was separated from the wing at the attachment points, with chordwise buckling. The right flap was separated from the wing at the attachment points with chordwise buckling. The right elevator was fire damaged. The left wing was shattered, and a three-foot section of the wing tip displayed crush damage. The left elevator displayed chordwise buckling, and heavy fire damage. The cabin and fuselage were consumed by fire. The horizontal stabilizer displayed heavy crush and fire damage. All flight control cables were located within the airplane. The cable system was traced from the attachment points on the flight controls to the control surface attachment points. The cables were cut for extraction purposes. Examination of the engine revealed crush and fire damage. The propeller was separated from the engine, and the propeller hub remained attached to the crankshaft flange. Both propeller blades exhibited twisting and chordwise scoring. The fuel system was heavily fire damaged. The right magneto produced ignition sparks from all lead towers when rotated. The left magneto was fire damaged. All spark plug electrodes were dry and tan in color. The oil pump was intact and there was no evidence of debris in the pressure screen. The crankshaft rotated and compression and suction was noted on all cylinders. Internal gear and valve train continuity was confirmed. The examination of the airframe and engine failed to disclose evidence of pre-impact failure or malfunction. MEDICAL AND PATHOLOGICAL INFORMATION The Pasco & Pinellas County medical examiner, Largo, Florida, preformed the postmortem examination on the private pilot on September 1, 2002. The cause of death was multiple blunt trauma. The toxicological examinations were negative for carbon monoxide, cyanide, drugs and alcohol. Traces of Propranolol were detected in the blood, kidney, liver and urine. Propranolol decreases cardiac rate and output, reduces blood pressure, and is effective in the prophylaxis of migraine. ADDITIONAL INFORMATION The airplane wreckage was released to CTC Services Aviation (LAD Inc.) on September 11, 2002.
