On January 8, 2012, about 1130 eastern standard time, an experimental, amateur-built Bowers Fly Baby 1-A, N4626, was destroyed when it impacted the ground immediately after takeoff from Jackson County Airport (19A), Jefferson, Georgia. Day, visual meteorological conditions prevailed and no flight plan was filed. The certificated private pilot was fatally injured. The local, personal flight was conducted under the provisions of 14 Code of Federal Regulations Part 91.

According to one eyewitness, the airplane departed runway 35, climbed to between 100 and 200 feet above ground level (agl), stalled, spun about one-half turn to the right, and impacted the ground approximately 45 degrees nose down. The eyewitness further reported that prior to departure, the pilot had reported that he was attempting to diagnose an engine problem; however, the engine sounded as though it was producing power during the takeoff roll.


The pilot, age 51, held a private pilot certificate for airplane single-engine land, and a third class medical certificate issued August 6, 2009. According to Federal Aviation Administration (FAA) records, the pilot reported 2,082 total flight hours.


The single-seat, open-cockpit, folding-wing monoplane was manufactured in 1972. It was powered by a Continental A-65-F, 65-horsepower engine. Review of copies of the airframe maintenance logbook records showed a conditional inspection was completed November 29, 2011, at a recorded tachometer reading of 1,425.5 hour, or 343.0 total hours time in service. According to the engine maintenance logbook, the engine was found to be airworthy and installed on the airplane on November 29, 2011 by a certificated airframe and powerplant mechanic; however, the entry indicated that the total time and time since major overhaul were unknown. No other engine logbooks were located. According to an email from the mechanic, he received the engine as part of a project in April, 2010 and there were no logbooks. He further reported that the engine, when installed on the accident airplane, ran "smooth and strong" when started.


The 1135 recorded weather observation at 19A included calm wind, visibility 7 miles, scattered clouds at 4,600 feet agl, broken clouds at 12,000 feet agl, temperature 12 degrees C, dew point 12 degrees C, and barometric altimeter 30.21 inches of mercury.


The airport was equipped with a single runway oriented north to south and designated as 17/35. The runway was 5,009-feet-long and 75-feet-wide, and constructed of asphalt. The airport did not have an air traffic control tower. Communication was accomplished utilizing a common traffic advisory frequency; however, transmissions were not recorded.


According to an FAA inspector that responded to the accident location, flight control cable continuity was confirmed to all flight controls and the airplane was consumed by a post-crash fire. He further reported that an engine cowling had been replaced sometime prior to the accident flight in order to accommodate the engine installation.

A post-accident examination was conducted on the engine and propeller by an FAA inspector. Corrosion was noted on the spark plugs and a considerable amount of water was found within the engine. The engine and both magnetos were thermally damaged. The spark plugs were removed and appeared to be oil-coked. Continuity was confirmed from the propeller flange to the rear accessory pad and all cylinders operated normally. The left magneto was removed from the accessory pad and the cotter pin for the drive shaft castellated nut could not be located. The right magneto was then removed. The distributor gear was unsecured inside the housing and the castellated nut, cotter pin, and washers for the drive shaft could not be located. The inside of the housing had signatures similar to galling. No other preimpact anomalies were found that would have precluded normal operation.


An autopsy was performed on the pilot on January 10, 2012, by the Georgia Bureau of Investigation, Division of Forensic Sciences, as requested by the Jackson County Coroner. The autopsy findings included multiple injuries, and the report listed the specific injuries. The cause of death was reported as multiple injuries.

The FAA's Civil Aerospace Medical Institute performed forensic toxicology on specimens from the pilot and no drugs of abuse were detected.


The carburetor icing probability chart from the FAA Special Airworthiness Information Bulletin (SAIB): CE-09-35 Carburetor Icing Prevention, June 30, 2009, shows a probability of serious icing at cruise power at the temperature and dew point reported at the time of the accident.

According to the Illustrated Parts Catalog for the engine, both magnetos were Eisemann model AM-4. According to figure 17 "Rotor Shaft Assembly" in the Eisemann Magnetos Service Handbook for the AM-4, a cotter pin was to be installed through the castellated nut and rotor shaft.
