On Sunday, January 16, 1994, at 1215 eastern standard time, a Bellanca 8KCAB, N41826, collided with the ground while on final approach during a power-off forced landing at Middletown, Ohio. The certificated airline transport pilot, the sole occupant was not injured, while the airplane sustained substantial damage. The personal flight was being operated under 14 CFR 91, and originated in Moraine, Ohio. Visual meteorological conditions prevailed at the time and a flight plan was not filed.

According to the pilot, during cruise flight at 2000 feet MSL he noticed both the oil temperature and oil pressure gages were indicating zero. He stated that he looked out of the airplane to see if there was any evidence of oil, but there was none. The pilot stated that he decided to return to the airport and not land sooner as he thought it "appeared to be only an indication problem. Within approximately 2 minutes engine rpm started decreasing slowly then engine started shaking violently. At that time I pulled mixture and picked the only field I thought I could make...The field was short with trees at both ends and plowed north/south. I attempted landing south but due to the shortness of the field I could not stop without hitting trees."

The engine was removed to Moraine Aircraft in Moraine, Ohio, for further examination. The examination included removing the oil sump and accessory case. When the oil sump was removed and the oil was drained out of the oil hoses, there was evidence of water in the oil. The interior of the sump contained pieces of bearing material. The connecting rod on the number one cylinder separated at the large end resulting in the piston being jammed in the cylinder. When the accessory case was removed there was evidence of aluminum melting in the area of the bearing around the oil pump. According to the FAA aviation safety inspector, there was starvation of oil in the engine.
