N1CYTemco GC-1B · 1948

On July 28, 2014, about 1000 eastern daylight time, a Temco GC-1B, N1CY, impacted a swamp shortly after departure from Flying-A-Ranch Airport (FL84), Yulee, Florida. The airline transport pilot was fatally injured. The airplane sustained substantial damage to the firewall and fuselage. Visual meteorological conditions prevailed and no flight plan was filed for the personal flight. The airplane was registered to and operated by a private individual under the provisions of Title 14 Code of Federal Regulations Part 91. The flight was originating at the time of the accident.

According to an eyewitness, he observed the airplane depart on runway 5 and noted that the "engine rpm's were low but steady." About 200 feet above ground level, the airplane banked left, "stalled," and descended out of his view.

According to Federal Aviation Administration (FAA) records, the pilot held an airline transport pilot certificate with ratings for airplane single-engine land, multiengine land, and single-engine sea. In addition, he held a flight instructor certificate with ratings for airplane single and multiengine, and instrument airplane. He held a Federal Aviation Administration first-class medical certificate that was issued on May 8, 2014, with a limitation of "must wear lenses for distant – possess glasses for near vision." At that time, the pilot reported 30,000 total hours of flight time, of which, 75 hours were in the previous six months of the medical exam. No pilot logs could be located.

According to FAA records, the airplane, manufactured in 1948, was registered to the pilot/owner in 1980. It was equipped with a Continental Motors O-300-A, 145-hp engine. According to airplane maintenance logbooks, the most recent annual inspection was completed on June 8, 2014, and at that time, the airplane had accumulated 2,934.8 hours in-service.

The airport was privately-owned and did not have an air traffic control tower. The airport was equipped with one runway designated as runway 5/23. The runway condition was not reported. The turf runway was 2,000 feet-long by 100-feet-wide, and a 25-foot tall tree was located 650 feet from the departure end of runway 5. The airport elevation was approximately 25 feet above mean sea level.

The 0955 recorded weather observation at Fernandina Beach Municipal Airport (FHB) , Fernandina Beach, Florida, located approximately 6 miles to the northeast of the accident location, included wind from 260 at 7 knots gusting to 14 knots, visibility 10 miles, sky clear, temperature 30 degrees C, dew point 24 degrees C; barometric altimeter 29.97 inches of mercury.

The airplane impacted terrain in a marshy area approximately 0.2 nautical miles from the departure end of runway 5. The airplane came to rest in the marsh and was partially submerged. A postaccident examination of the wreckage confirmed flight control to all flight control surfaces. The main fuel tank was approximately three-quarters full of fuel and the auxiliary tank was nearly empty. Samples of fuel drained from the airframe were absent of debris or water. The fuel selector was position to the main fuel tank. The throttle and mixture controls were in the full forward position. The carburetor heat control was in the "OFF" position.

A postaccident examination of the engine revealed that continuity of the crankshaft and valvetrain was confirmed to all cylinders and to the rear of the engine. The top spark plugs were removed and exhibited normal wear when compared to the Champion Check-A-Plug chart, and were light gray in color. Thumb compression was obtained on all cylinders when the propeller was rotated by hand. All valves were in place and no anomalies were noted. The magnetos sparked on all terminals when the crankshaft was rotated, and the impulse couplings operated without anomaly. The fuel pump contained fluid similar to 100LL aviation fuel and the fuel screen was free of debris.

The engine controls remained attached to the carburetor and moved without anomaly. The carburetor was removed and disassembled. The carburetor bowl contained about 4oz of brown water, and the bottom of the bowl was corroded and rusted. The water was similar in color and smell to the water in the swamp surrounding the wreckage. No other anomalies were noted with the carburetor.

An autopsy was performed on the pilot's remains on July 29, 2014, by the Office of the Medical Examiner, Jacksonville, Florida. The autopsy findings included "multiple blunt force injuries," which was also listed as the cause of death.

In addition, the heart was enlarged, and demonstrated hypertensive heart disease. It weighed 475 grams and was described as having a floppy and soft consistency. The left ventricle and the interventricular septum measured 15 and 17 mm, respectively. For comparison, the average weight of a heart of a man his weight is 395 grams with a range from 299-521 grams and the average left ventricle and the interventricular septum are 12.3 mm (SD 1.6 mm) and 13.6 mm (SD 2 mm) respectively. In addition, mild coronary artery disease with about 30% stenosis was seen in multiple arteries. There was no evidence of acute myocardial infarct or coronary thrombosis. Microscopic examination of the left ventricular septum identified patchy mild myocardial fibrosis with no sign of myocarditis. Finally, cirrhosis of the liver was also identified.

Forensic toxicology was performed on specimens from the pilot by the FAA Bioaeronautical Sciences Research Laboratory, Oklahoma City, Oklahoma. The toxicology report stated no ethanol was detected in the vitreous fluid and no drugs were detected in the blood.

The carburetor icing probability chart from Federal Aviation Administration (FAA) Special Airworthiness Information Bulletin (SAIB): CE-09-35 Carburetor Icing Prevention, June 30, 2009, showed a potential for icing at cruise/glide engine power settings at the temperature and dew point reported around the time of the accident.
