On May 6, 2023, about 1307 eastern daylight time, a Piper PA-28-140, N678FL, was substantially damaged when it was involved in an accident near Clyde, Ohio. The private pilot was seriously injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot reported that he departed from Fremont Airport (14G), Fremont, Ohio at 1150. He performed a touch-and-go landing at Fostoria Metro Airport (FZI), Fostoria, Ohio, and was planning a touch-and-go landing at Sandusky County Regional Airport (S24) before returning to 14G, his home airport. After an uneventful touch-and-go landing at S24, during the initial climb, the engine lost all power. He performed a forced landing into a cornfield about ½ mile northeast of S24. The pilot was met by first responders and was taken to a nearby hospital for treatment of his injuries. The pilot later reported that he was unsure why the engine stopped, but stated, “…could be a failure to switch tanks.” Inspectors with the Federal Aviation Administration (FAA) responded to the accident site and examined the wreckage. The fuselage came to rest upright, and there was no fire. The right wing separated from the fuselage during the impact sequence and was found inverted and adjacent to the main wreckage, with the right main landing gear still attached. The fuselage was buckled. The engine remained attached to the fuselage, and the propeller remained attached to the engine. The left wing was undamaged.  Although the right wing fuel tank was ruptured from impact, about 7 gallons of fuel were recovered from that tank. The left wing fuel tank was intact and undamaged. The left tank was drained at the accident site by the inspectors and about 1 quart of fuel was recovered. The cockpit fuel tank selector was in the left tank position. The wreckage was recovered to a hangar where an additional examination of the engine and fuel system was performed. The engine contained about 4 quarts of clean oil. There was no visible damage to the engine case. Internal engine continuity was confirmed and valve action was correct. The fuel gascolator was removed and examined. It was dry and contained some small, black particulates. The engine-driven fuel pump was actuated by hand; a few drops of fuel were expelled. The interior of the pump was normal in appearance. The carburetor air box was unobstructed. The carburetor was disassembled. The bowl was free of contaminants and contained about 1 tablespoon of fuel. The brass floats were uncompromised. The electric fuel boost pump was energized with aircraft battery power; it pumped normally. The fuel tank selector valve was disassembled and operated normally. The FAA inspectors reported that the airplane was last fueled with 18.8 gallons on March 30, 2023. According to aircraft and pilot records, the airplane was operated about 3.97 hours since the last refueling.
