N4614S

HISTORY OF FLIGHTOn June 28, 2019, about 1715 central daylight time, a Beechcraft BE-58 airplane, N4614S, impacted terrain during an approach to the Hiawatha Municipal Airport (K87), Hiawatha, Kansas. The pilot was fatally injured, and the airplane was destroyed. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 cross-country personal flight.

The pilot was not in contact with air traffic control during the cross-country flight from Augusta Municipal Airport (3AU), Augusta, Kansas. Review of radar information revealed that the airplane proceeded in a northeast direction from the origin airport toward K87the destination; however, the flight track stopped about 3/4-mile northeast of K87 and the final minutes of the flight were not captured.

A witness reported that the airplane approached the airport from the south and then proceeded north-northeast as if to enter the traffic pattern. He added that the airplane appeared to climb and then started a left turn. Just after starting the turn, the airplane flipped inverted, the nose dropped, and the airplane descended from view behind terrain. The witness saw smoke and called 911. PERSONNEL INFORMATIONThe pilot last medical certificate was issued on March 09, 2017, with no limitations. The pilot's second-class medical certificate expired on March 31, 2019, but he had completed the BasicMed flight medical. The pilot's BasicMed course date was April 16, 2019, and the Comprehensive Medical Examination Checklist (CMEC) was completed on April 12, 2019. WRECKAGE AND IMPACT INFORMATIONThe airplane wreckage was located in a corn field about 1-mile northeast of K87. The airplane impacted terrain on its bottom fuselage and came to rest upright on a 171° heading. A post-crash fire consumed a majority of the cabin and the inboard section of the wings. The wreckage was confined to one area, and all major components were accounted for on-site.

Flight control continuity was limited through the center section of the fuselage due to fire damage, however, the connection at each of the respective flight control surfaces was confirmed.

The cockpit/instrument panel was impact and fire damaged. The landing gear handle appeared to be in the down/landing gear extended position. A review of the landing gear actuator position corroborated the landing gear was in the down position. The right flap actuator was partially extended, which corresponded to a flap's 15° extended position.

The left and right engines remained attached to their respective airframe locations, and both engines had impact and fire damage. The right 3-bladed propeller separated from the engine crankshaft flange and was located underneath the airplane. The left 3-bladed propeller remained attached to the engine; neither propeller was in the feathered position

Both engines were rotated by hand, and thumb compression and suction were noted on each cylinder. The valve covers were removed and continuity through the valve train to the accessory section was observed. The left engine's left magneto produced spark at each terminal; the engine's right magneto was fire damaged and would not rotate. The right engine's left magneto produced spark at each terminal. The right magneto was fire damaged and did not produce spark at the terminals; however, spark was observed at the magneto points.

Each engine's fuel system, including the fuel manifold, fuel pump, fuel nozzles, and fuel screen were field examined, and no pre-impact abnormalities were noted. The top set of sparkplugs were removed from both engines, and normal combustion and wear signatures were observed.

Though the examination was limited by thermal and impact damage, no pre-impact abnormalities were observed during the airframe or engines examinations that would have precluded normal operations. MEDICAL AND PATHOLOGICAL INFORMATIONThe Frontier Forensics Midwest Morgue of Kansas City, Kansas, under the authority of the Brown County Coroner's Office, conducted an autopsy on the pilot. The cause of death was due to blunt traumatic injuries and severe burns.

The Federal Aviation Administration's (FAA) Forensic Sciences Laboratory, Oklahoma City, Oklahoma, conducted toxicological testing. The specimens were not tested for cyanide. The tests were negative for ethanol and tested drugs.
