HISTORY OF FLIGHTOn June 6, 2020, at 1523 eastern daylight time, a Cessna 172 airplane, N13520, was destroyed when it was involved in an accident near New Washington, Indiana. The student pilot was fatally injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 instructional flight. According to the pilot’s flight instructor, the pilot was to conduct a solo practice flight in preparation for his private pilot check ride. The flight was to include maneuvers in the northeast practice area, which is near New Washington. The flight instructor stated that he tracked the airplane on his phone and the flight track disappeared about 20 minutes into the flight. The pilot was supposed to return by 1700. The recorded automatic dependent surveillance-broadcast (ADS-B) data revealed that the airplane departed Bowman Field Airport (LOU), Louisville, Kentucky, at 1509, proceeded northeast along the Ohio River, and climbed to about 3,000 ft above ground level (agl). About 2 nautical miles south of New Washington, the airplane completed 3 consecutive left steep turn maneuvers (see figure 1) and remained about 3,000 ft agl. At 1523:09 the airplane descended and proceeded southeast; this flight track continued into a steep dive in excess of 10,000 ft per minute and a calculated groundspeed of about 170 kts. The final ADS-B data point was recorded at 1523:34 and 165 ft agl. Figure 1 – Accident flight path with the initial impact point overlaid on a Google Earth map. PERSONNEL INFORMATIONThe flight instructor stated that he and the student pilot had flown together the day before the accident when they completed a “mock check ride” in preparation for the student's private pilot check ride, which was scheduled for 6 days later. The flight instructor added the student was well prepared to pass the check ride, but that the student had asked permission for another solo flight for additional practice. The flight instructor stated that the student was “one of his best” and that he was “always well prepared.” WRECKAGE AND IMPACT INFORMATIONThe airplane wreckage was located in a field and the initial impact point was identified by a few shallow craters and disturbance of dirt (see Figure 2). The wreckage path was oriented on a 130° heading and extended about 300 yards. All major components of the airplane were located at the accident site and there was no post impact fire. The responding Federal Aviation Administration inspectors completed an initial examination of the wreckage debris, which was scattered across the field. The propeller had separated from the engine and was found about 30 yards from the initial impact. The wings both separated from the fuselage at the wing roots and were about 100 yards from the initial impact point. The engine separated from its mount and was about 220 yards from the initial impact point. The farthest piece of wreckage was a portion of the left fuel tank and filler port.

A postaccident examination revealed that the airframe exhibited significant impact damage and separations. The flight cables remained attached to their respective control surfaces, and control continuity was confirmed through several tensile overload separations in the cockpit area. The engine sustained significant impact damage and most accessories were impact separated. The crankshaft was manually rotated through with binding noted during rotation due to the impact damage. Continuity of the crankshaft to the rear gears and to the valve train was confirmed. When the crankshaft was rotated, compression and suction were obtained for each cylinder. One propeller blade exhibited longitudinal twisting toward the blade face and was impact separated about midspan. The outboard portion of the blade was not observed. The other blade was bent aft about 100° and exhibited longitudinal twisting toward the blade face, leading/trailing edge gouges, and “S” bending. There were no anomalies with the engine or airframe that would have precluded normal operation. MEDICAL AND PATHOLOGICAL INFORMATIONAn autopsy of the pilot was performed by the Scott Funeral Home, Jeffersonville, Indiana, and authorized by the Clark County Chief Deputy Coroner, Clark County, Indiana. The cause of death was multiple blunt force injuries and the manner of death was accident. Toxicology testing performed at the FAA Forensic Sciences Laboratory found no drugs of abuse.
