On September 5, 2005, approximately 1225 central daylight time, a single-engine Cessna A188B agricultural airplane, N9083G, was destroyed while maneuvering at the Blytheville Municipal Airport (HKA) near Blytheville, Arkansas. The airplane was registered to Mid-Continent Aircraft Corporation of Hayti, Missouri, and was being operated by Myers Flying Service of Blytheville, Arkansas. The airline transport pilot, the sole occupant of the airplane, was fatally injured. Visual meteorological conditions prevailed for the local 14 Code of Federal Regulations Part 137 aerial application flight. In a telephone interview with an NTSB representative, a witness stated that he had just completed placing his aircraft in a hangar and was entering his vehicle when he saw the accident airplane fly down HKA Runway 18 (a 5,001-feet long by 75-feet wide asphalt runway) at a low altitude. The airplane then pulled-up and began a climbing right turn. The witness estimated the bank angle to be "in excess of 60 degrees as the wings were more than 45 degrees with the horizon." The witness added that the engine "sounded normal and at full power" and the airplane was "steadily losing altitude." The witness reported that he did not hear any engine power changes prior to impact. A Federal Aviation Administration (FAA) inspector and a representative from Cessna Aircraft performed an on-scene examination of the wreckage. The FAA inspector reported the airplane's right wing impacted first and the airplane came to rest in an upright position. The Cessna representative established cable continuity to the airplane's flight controls. A post-impact fire consumed the cockpit, empennage, and the right wing. The engine separated and was found approximately 40 feet from the main wreckage. The 1973-model Cessna A188B, a low wing single-seat agricultural application airplane, serial number 1880136T, was powered by a single Continental IO-520-D (23) engine, rated at 300 horsepower. On December 7, 2005, an inspection was performed on the engine under the supervision of a NTSB investigator, at Teledyne Continental Motors, Inc., near Mobile, Alabama. The engine examination did not reveal the presence of any preimpact abnormalities that would have prevented normal operation and production of rated horsepower. According to the operator, the most recent aircraft maintenance action was a replacement of an air conditioner unit two days prior to the accident. He also stated that the airplane had flown within the subsequent days with no reports of deficiencies. The operator also reported that the airplane departed with approximately 54-gallons of fuel and estimated 60-gallons of Malathion insecticide prior to the accident. The engine and airframe logbooks were not available for review during the course of the accident investigation. The pilot held a FAA Airline Transport Pilot certificate with rating for single-engine land airplane. The pilot's most recent FAA medical certificate was issued on January 14, 2005, and the pilot reported his total flight time as 20,634-hours, with 413-hours in the preceding six months. The pilot's personal logbooks were not located during the course of the accident investigation. An autopsy was performed on the pilot on September 6, 200, by the Arkansas State Crime Laboratory, Medical Examiner Division. Toxicological testing was performed by the FAA Toxicology Accident Research Laboratory, Oklahoma City, Oklahoma. At 1153, the automated surface observing system at HKA, located approximately one half mile north east of the accident site, reported wind from 070 degrees at six knots, visibility 10 statute miles, clear sky, temperature 82 degrees Fahrenheit, dew point 64 degrees Fahrenheit, and a barometric pressure of 30.21 inches of Mercury.
